Desserts
This angel food cake made with Splenda delivers the signature light-as-air texture without the sugar overload—perfect for special occasions or guilt-free indulgence. The key lies in properly folded egg whites and a precise baking technique that creates those signature air pockets. Unlike traditional recipes, Splenda requires careful measurement to maintain moisture and sweetness balance.
What sets this recipe apart is the foolproof method for achieving that iconic fluffy crumb without butter or oil. The cake rises dramatically in the oven, then collapses slightly as it cools, creating the signature tender yet airy texture. Splenda's granular form mimics sugar's behavior, though we adjust the amount slightly to prevent dryness.
The result is a delicate, melt-in-your-mouth dessert with a clean sweetness that pairs beautifully with fresh berries or whipped cream. This version maintains all the charm of classic angel food cake while accommodating dietary preferences. The recipe yields a 9-inch cake that serves 8-10, perfect for celebrations or satisfying cravings.
For best results, use room-temperature eggs and avoid overmixing the batter. The cake's texture comes from proper folding technique and precise baking temperature. Let's create this lighter-than-air masterpiece with confidence.
Ingredients for angel food cake made with splenda
Twelve egg whites, precise measurements, and patience create this ethereal Splenda angel food cake.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Egg Whites 🥚 | 12 whole | Room temperature, pasteurized preferred |
| Splenda Granulated Sweetener 🍬 | 1 ½ cups | Packed, not scooped |
| Unsalted Butter 🧈 | ¼ cup | Cold, cubed for folding |
| Pure Vanilla Extract 🌿 | 2 tsp | High-quality, pure vanilla |
| Cream of Tartar 🧂 | ½ tsp | Essential for stability |
| Fine Sea Salt 🧂 | ¼ tsp | Diamond Crystal preferred |
| Unbleached All-Purpose Flour 🌾 | 1 ½ cups | Sifted, light texture |
| Cake Flour 🌾 | ½ cup | For delicate crumb |
| Baking Powder 🧂 | 1 tsp | Aluminum-free |
| Cream of Tartar 🧂 | ¼ tsp | For dry ingredients |
| Vegetable Oil 🫒 | 2 tbsp | Light, neutral flavor |
| Cream of Tartar 🧂 | ¼ tsp | For dry mix stability |
The egg whites are non-negotiable—room temperature and pasteurized for optimal volume. Splenda requires careful measurement: pack the cups to avoid air pockets, unlike granulated sugar. For the dry ingredients, sift everything through a fine-mesh sieve to eliminate clumps. King Arthur or Bob's Red Mill flours work best for their consistent protein content. The cream of tartar is critical: it stabilizes the egg whites and balances the sweetener's unique properties. If you're unsure about the Splenda-to-sugar conversion, start with 1.25 cups and adjust to taste after baking.
No cream of tartar? Substitute lemon juice at half the amount, but the texture may be slightly less stable. For the oil, avocado oil or light olive oil work, but avoid strong-flavored varieties. If you prefer a slightly richer cake, replace 2 tbsp of Splenda with honey or maple syrup (reduce other liquids by 1 tbsp). The vanilla extract should be pure, not imitation—Nike or McCormick brands are reliable. For a gluten-free version, substitute the all-purpose flour with a 1:1 gluten-free blend, but expect a denser texture. Always use unsalted butter to control the final salt level precisely.
Store the cake in an airtight container at room temperature for up to 3 days or refrigerate for up to 5 days. For longer storage, freeze slices wrapped in plastic for up to 3 months. To serve, dust with powdered sugar or top with fresh berries for a light contrast. The cake reheats beautifully: wrap a slice in foil and warm at 300°F for 5-7 minutes. Avoid overmixing the dry ingredients—fold just until combined to preserve the airiness. The cake will rise dramatically in the oven, so do not overfill the tube pan.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this trick—whipping the egg whites with cream of tartar until stiff peaks form gives that signature angel food lightness. No stand mixer? A hand mixer works just fine, and honestly, the extra elbow grease makes me feel like I’m baking from scratch (even when I’m not).
- Vanilla Kisses: That pure vanilla extract isn’t just flavoring—it’s the star. The butter swirled into the batter adds a buttery richness without overpowering, while the Splenda keeps it sweet without the heaviness. It’s the kind of cake that makes you close your eyes and take a second bite.
- Birthday Table Hero: This cake is my go-to for celebrations—no one guesses it’s sugar-free. The fluffy texture holds up for slicing, and the neutral flavor means it pairs perfectly with fruit compotes, whipped cream, or even a drizzle of chocolate. (Yes, even my picky aunt approves.)
- Leftovers? No Problem: Unlike some cakes that turn dense after a day, this one stays light and moist for days. I’ve had slices for breakfast the next morning, and they’re just as good—if not better—than fresh. Plus, the recipe’s budget-friendly: egg whites are cheap, and Splenda stretches farther than sugar. Win-win.
Step-by-step instructions for angel food cake made with Splenda
This method guarantees a perfectly fluffy, guilt-free cake that's light enough to float.
Prepare the Egg Whites for Maximum Stability
Separate the 12 whole large egg whites carefully, ensuring no yolk traces remain—they'll prevent proper whipping. Place the whites in a spotless, grease-free bowl. I use a glass bowl because it's non-reactive and makes it easier to spot any impurities. Add the 0.5 teaspoon cream of tartar and 0.25 teaspoon fine sea salt to the egg whites and whisk gently to distribute evenly.
Here's the thing—cream of tartar is non-negotiable. It stabilizes the egg whites, helping them hold their volume and structure. Without it, your cake will collapse like a deflated balloon. Use a stand mixer fitted with the whisk attachment and beat the egg whites on low speed for 2 minutes to break up any large bubbles that form during separation.
Whip to Stiff Peaks with Precision
Increase the mixer speed to high and whip the egg whites for 5-7 minutes until they form stiff peaks. You'll know they're ready when the peaks hold their shape when the whisk is lifted and the mixture looks glossy, almost like mercury. Be patient—rushing this step is the fastest way to end up with a dense cake.
I like to stop the mixer occasionally to scrape down the sides with a silicone spatula. This ensures even whipping and prevents any unwhipped egg whites from settling at the bottom. If you're unsure about the doneness, test by lifting the whisk—if the peak stands straight up and doesn't flop over immediately, you're good to go.
Gradually Incorporate Sweetener and Flour
With the mixer still running on low speed, gradually add the 1.5 cups Splenda granulated sweetener in three additions, allowing each to fully dissolve before adding the next. This gradual approach prevents the sweetener from deflating your carefully whipped egg whites. Once the sweetener is fully incorporated, remove the bowl from the mixer.
In a separate bowl, whisk together the 1.5 cups unbleached all-purpose flour, 0.5 cup cake flour, 1 teaspoon baking powder, and the remaining 0.25 teaspoon cream of tartar. Sift the dry ingredients together once to aerate them—this helps create a lighter crumb. Using a spatula, gently fold one-third of the flour mixture into the egg white mixture in the large bowl, being careful not to deflate the batter.
Fold in Remaining Ingredients with Care
Add the remaining flour mixture in two more additions, folding gently just until combined after each addition. The batter should be thick but still pourable. Next, fold in the 0.25 cup cold cubed unsalted butter and 2 teaspoons pure vanilla extract using the same gentle folding motion. The butter should be incorporated completely, but don't overmix—you're aiming for a smooth, ribbon-like consistency.
Finally, fold in the 2 tablespoons vegetable oil. This step might seem counterintuitive—why add oil to an angel food cake?—but it helps create a tender crumb and prevents the cake from drying out. The batter should be smooth and glossy, with no visible streaks of flour. If you see any dry spots, fold them in gently to ensure even distribution.
Bake to Golden Perfection
Preheat your oven to 350°F and prepare an ungreased 10-inch tube pan by lining the bottom with parchment paper that extends up the sides. This prevents the cake from sticking and allows for easy removal. Pour the batter into the prepared pan, smoothing the top with a spatula. Tap the pan gently on the counter a few times to release any air bubbles.
Bake for 35-40 minutes until the top is golden brown and a toothpick inserted into the center comes out clean. The cake should pull away slightly from the sides of the pan and spring back when gently pressed. Here's a pro tip: I like to rotate the pan halfway through baking for even heat distribution—this prevents any potential hot spots that could cause uneven browning.
Cool and Invert for Maximum Fluffiness
Remove the cake from the oven and let it cool in the pan for 5 minutes. Then, run a thin knife around the edge to loosen it from the pan. Invert the cake onto a wire rack and let it cool completely, about 1 hour. This cooling process is crucial—it allows the cake to set properly and develop its signature light, airy texture. The longer you wait, the better the final result.
Once fully cooled, you can serve the cake as is or frost it with your favorite light whipped cream or fresh berries. The cake's natural sweetness from the Splenda pairs beautifully with tart fruits like raspberries or strawberries. And remember, this cake keeps well in an airtight container for up to 3 days at room temperature—though I doubt it'll last that long!
Pro Tips For Making Angel Food Cake Made With Splenda
- WHISK EGGS AT ROOM TEMP: I learned this the hard way—cold egg whites from the fridge won’t whip properly, no matter how much you beat them. Pop those whites in a bowl and let them sit for 30 minutes before starting. Your meringue will be stiffer and more stable from the get-go, especially when you’re using Splenda, which can make batters slightly denser.
- SIFT SPLENDA FIRST: Dumping Splenda straight into the egg whites creates clumps that won’t dissolve, even when whipped. Sift it through a fine-mesh sieve directly into the bowl before adding the whites—this ensures an even distribution and a smoother batter. (Yes, even if you’re in a hurry, take the 10 seconds to do this.)
- STOP BEATING AT SOFT PEAKS: Over-whipped egg whites turn into a dry, grainy mess. Test for soft peaks by lifting the whisk: the meringue should hold its shape but still have a slight drizzle at the tip. For Splenda-sweetened cakes, this is especially crucial—too much air collapses during baking, leaving a dense center.
- GREASE PAN WITH BUTTER, THEN FLOUR: This isn’t the prettiest method, but it’s the tastiest. Lightly coat your tube pan with melted butter, then dust with flour, tapping out excess. The butter prevents sticking, while the flour creates a nonstick barrier that keeps the cake from clinging to the sides. Skip the flour, and you’ll spend 10 minutes scraping cake off the pan.
Perfect pairings for angel food cake made with splenda
Fruit Toppings
Fresh berries are the perfect topping for this angel food cake—their natural tartness balances the sweetness of the Splenda. I love using strawberries or raspberries, sliced into ¼-inch pieces and arranged in a circular pattern on top. For a tropical twist, try mango slices or kiwi, both of which add vibrant color and a refreshing contrast. 🍓
If you prefer a more elegant presentation, create a berry compote by simmering 1 cup mixed berries with 2 tablespoons Splenda and 1 teaspoon lemon juice for 5 minutes. Strain and drizzle over the cake before serving. The compote adds moisture and a glossy finish that makes the cake look restaurant-worthy.
Whipped Cream Variations
Lightly sweetened whipped cream is a classic pairing, but don’t stop there! For a citrus twist, fold 1 teaspoon lemon zest into the whipped cream before topping. For a coffee lover’s version, add 1 tablespoon instant espresso powder to the cream while whipping. Both options enhance the cake’s flavor without overpowering it. ✨
For a richer texture, replace some of the heavy cream with whipped mascarpone cheese—mix ½ cup mascarpone with 1 cup heavy cream and 2 tablespoons powdered sugar. This creates a decadent, yet still light, topping that feels indulgent. Store-bought whipped cream works in a pinch, but homemade always tastes fresher.
Drizzles and Sauces
A chocolate ganache adds a sophisticated touch. Melt 4 ounces dark chocolate (70% cocoa) with ¼ cup heavy cream, then drizzle over the cake in zigzag lines. Let it set for 10 minutes before serving. For a caramel option, heat ½ cup granulated sugar until melted, then add 2 tablespoons heavy cream and drizzle immediately. 🍫
If you prefer something lighter, try a honey-lemon drizzle. Warm 2 tablespoons honey with 1 tablespoon lemon juice and brush it over the cake’s surface. The acidity cuts through the sweetness, creating a bright, refreshing finish. This works especially well with berry toppings.
Unexpected Pairings
For a savory contrast, sprinkle the cake with toasted coconut flakes or crushed pistachios. The nutty crunch adds texture and a subtle earthiness that complements the cake’s sweetness. I also love adding a pinch of flaky sea salt on top—it enhances the flavors and balances the sweetness beautifully. 🌴
If you’re feeling adventurous, try a spiced cream cheese frosting. Mix 4 ounces cream cheese with 2 tablespoons powdered sugar, ½ teaspoon vanilla, and a pinch of cinnamon or cardamom**. Spread a thin layer over the cake and top with fresh fruit for a unique twist on a classic dessert.

Frequently asked questions
Why does this Splenda angel food cake need more cream of tartar than regular recipes?
Splenda's unique molecular structure requires extra cream of tartar to stabilize the egg whites properly. The acidity helps compensate for the sweetener's different density, preventing collapse during baking. Use the full 0.75 teaspoon total (0.5 tsp with egg whites + 0.25 tsp with dry ingredients) for best results.
Can I substitute Splenda for regular sugar in any angel food cake recipe?
Not directly—this recipe is specifically formulated for Splenda. Regular sugar has different moisture properties that affect texture. If you must substitute, reduce to 1.25 cups and add 1 tablespoon water to compensate for Splenda's lower moisture content. The cake may be slightly denser.
What's the secret to getting that signature "float" texture?
The key is proper cooling! Let the cake cool 1 full hour upside down before removing from the pan. This allows the cake to set properly while maintaining maximum air pockets. Never rush this step—patience creates that signature light-as-air texture that makes angel food cake so special.
My cake turned out dense—what went wrong?
Most likely you overmixed the batter or didn't whip the egg whites to stiff peaks. Also check these common issues: using cold egg whites, not sifting dry ingredients properly, or opening the oven door too early. For next time, whip egg whites to glossy, stiff peaks and fold dry ingredients just until combined.
How can I make this cake gluten-free?
Replace the 1.5 cups all-purpose flour and 0.5 cup cake flour with 2 cups gluten-free 1:1 baking flour. Add 1 teaspoon xanthan gum to the dry ingredients.
