Ingredients for banana cake recipe with splenda
Five simple ingredients create this ultra-moist banana cake with caramelized top magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 whole | Spotty skin preferred for sweetness |
| Splenda Granulated Sweetener 🍯 | 1 ½ cups | Granulated for even distribution |
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Unsalted Butter 🧈 | ¾ cup | Room temperature for creaming |
| Large Eggs 🥚 | 2 whole | Room temperature for best mixing |
| Ground Cinnamon 🌿 | 1 tbsp | Freshly ground preferred |
| Baking Soda 🧂 | ½ tsp | Pure baking soda, not baking powder |
| Vanilla Extract 🍯 | 1 tsp | Pure vanilla extract preferred |
| Salt 🧂 | ¼ tsp | Fine sea salt preferred |
| Brown Sugar 🍚 | ¼ cup | Packed for moisture retention |
The bananas are everything here—ripe with brown spots means natural sweetness and perfect texture. Grab them from the grocery store's produce section when they're soft to the touch. Whole Foods or Trader Joe's tend to carry the sweetest varieties. Splenda is key for that classic banana cake flavor without the glycemic spike. I always buy the granulated version because it dissolves better than the packets. The flour? King Arthur brand if you want to splurge, but any all-purpose works fine. For the butter, Land O'Lakes unsalted is my go-to—it's consistent and reliable for baking.
No Splenda? White sugar at half the amount works in a pinch, but the cake won't be as moist. The brown sugar can be swapped for white if you're avoiding caramelized flavors, though I recommend keeping it for that extra depth. Fresh cinnamon is ideal, but ground cinnamon from the spice aisle is perfectly fine. If you're watching your sugar intake, you can reduce the Splenda by 2 tablespoons and add 1/4 cup unsweetened applesauce to maintain moisture. The vanilla extract should be pure—Nestlé or McCormick are solid choices, but anything labeled 'pure vanilla' will do.
This cake keeps beautifully—3 days at room temperature wrapped in plastic, or 5 days in the fridge. For longer storage, slice and freeze portions for up to 3 months. The caramelized top is best eaten fresh, but the moist layers stay tender for days. I always bake an extra batch and freeze slices for quick breakfasts. The cake reheats wonderfully in the microwave for 10-15 seconds to revive that fresh-from-oven warmth.
Why You'll Love This Recipe
- No-Fuss Mix-In: I swear by this recipe because it’s the kind of cake where you don’t even need to measure the bananas—just mash them right into the bowl. The Splenda keeps it sweet without the guilt, and the butter makes the crumb so tender, you’ll forget it’s "healthy."
- Moist Magic: That ripe banana flavor? It’s like a hug in cake form—naturally sweet, slightly caramelized, and the eggs bind it all together for a texture that’s almost too perfect. Honestly, I’ve made banana bread before, but this cake stays moist for days.
- Weeknight Workhorse: Double the batter, freeze half—this cake is my go-to for lazy mornings or last-minute gatherings. The flour and butter combo means it bakes up sturdy enough for slicing, and the Splenda keeps it from drying out overnight in the fridge.

I’ve made this on a budget, for birthdays, and even as a quick lunch when I was too tired to think. Reliable doesn’t get better than this.
Step-by-step instructions for banana cake with Splenda
Here's how to create a cake with ultra-moist layers and that perfect caramelized top.
Prepare the Bananas and Cream Butter and Sweeteners
Mash the 3 whole ripe bananas until completely smooth, with no visible lumps. I press them through a fine-mesh sieve to ensure an ultra-smooth texture that prevents dense spots in the cake. In a separate large mixing bowl, beat the 0.75 cup unsalted butter on medium speed until completely smooth and creamy—about 2-3 minutes. This ensures proper incorporation with the sweeteners.
Gradually add the 1.5 cups Splenda granulated sweetener and 0.25 cup packed brown sugar to the butter mixture. Beat on medium-high speed for 3-4 minutes until the mixture is light and fluffy. You'll see it nearly double in volume as air is incorporated—this creates the tender crumb we're after. Scrape down the sides of the bowl with a rubber spatula to ensure even mixing.
Add Eggs and Mix in Dry Ingredients
Add the 2 whole large eggs, one at a time, beating well after each addition. Mix on medium speed for 1-2 minutes until fully combined. The mixture should be thick and smooth. I always use room temperature eggs—they blend more easily and create a lighter texture. Stir in the 1 teaspoon vanilla extract and mix for 10 seconds until incorporated.
In a separate bowl, whisk together the 2 cups all-purpose flour, 1 tablespoon ground cinnamon, 0.5 teaspoon baking soda, and 0.25 teaspoon salt. Sift the dry ingredients directly into the wet mixture while mixing on low speed. Mix just until combined—you should still see small streaks of flour. Overmixing develops gluten and makes the cake dense. Stop mixing immediately when the batter is smooth and just barely combined.
Fold in Banana Puree and Prepare the Cake Pan
Remove the mixing bowl from the stand mixer and gently fold in the mashed bananas using a silicone spatula. Be careful not to overmix—just combine until the batter is smooth and uniform in color. The batter will be thick but should still be pourable. If it's too thick to fold easily, mix on low speed for 10-15 seconds to loosen it.
Preheat your oven to 350°F. Generously grease a 9-inch round cake pan with butter or baking spray, then line the bottom with parchment paper. I like to use a small piece that extends slightly up the sides to prevent sticking. Pour the batter into the prepared pan and smooth the top with a spatula. The batter should fill about 2/3 of the pan height—this ensures proper rising and a thick, moist cake.
Bake Until Golden and Springy
Bake the cake for 45-50 minutes, or until a toothpick inserted in the center comes out clean with just a few moist crumbs clinging to it. The edges should be golden brown, and the top should have a slightly caramelized crust. I like to tent the cake loosely with aluminum foil after 30 minutes to prevent over-browning if my oven runs hot.
For that perfect caramelized top, increase the oven temperature to 375°F during the last 5 minutes of baking. This creates the beautiful crust while keeping the interior moist. Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely before serving. The cooling process allows the cake to set properly and develop its full moisture.
Pro Tips For Making Banana Cake Recipe With Splenda
- Mash Bananas First, Then Sweeten: I learned this the hard way—adding Splenda directly to whole bananas means you’ll end up with a lumpy batter that fights you every step. Mash the bananas until completely smooth, then stir in the Splenda with the wet ingredients. This way, the sweetener dissolves properly and you avoid that dreaded "sugar clump" surprise later.
- Use Room-Temp Butter: Cold butter in banana cake batter is a recipe for dryness. Let that butter sit out for 30-45 minutes before creaming it with the Splenda—just until it’s soft enough to press a finger into but not fully melted. This ensures the cake stays moist without turning greasy, especially since Splenda doesn’t add the same moisture as sugar.
- Bake Until the Center Catches Up: The Splenda makes this cake bake faster than traditional versions, but the middle often feels underdone when the edges are golden. Insert a toothpick at the center—if it comes out with a damp crumb (not wet batter), pull it out. If it’s dry but the cake still jiggles slightly, give it 3-5 more minutes. Overbaking turns banana cake into a sad, dense brick.
- Swap 1 Egg for Mashed Avocado: I was skeptical until I tried it—replacing one egg with ¼ cup mashed avocado (yes, really) keeps the cake ultra-moist without altering the flavor. The avocado’s fat content mimics the richness of butter while cutting down on eggs, which can make Splenda-based cakes gummy if overused. Just don’t tell anyone unless they ask.
Troubleshooting your banana cake recipe with splenda
Dense Batter Fix
If your batter looks too thick to spread, add 1-2 tablespoons of warm water or milk while folding in the bananas. The goal is a thick but pourable consistency—think pancake batter. I've had to adjust this when using very ripe bananas that release extra moisture. If the batter is still too thick after adding liquid, mix on low speed for just 10 seconds to loosen it. 🌟
Cake Sticking to Pan
For a foolproof release, use a mix of butter and flour to grease your pan. Rub ½ tablespoon melted butter on the sides and bottom, then dust with 1 tablespoon flour, tapping out excess. I also recommend placing a small piece of parchment paper on the bottom—this prevents the cake from sticking while allowing easy removal. If it still sticks, run a thin knife around the edges before inverting onto a plate.
Dry or Crumbly Texture
This usually happens when the cake overbakes or lacks sufficient moisture. First, check your baking time—remove the cake when a toothpick comes out with a few moist crumbs, not completely clean. If it's still dry, try adding ¼ cup Greek yogurt or applesauce to the batter next time. For already-baked dry cake, brush warm slices with simple syrup (equal parts sugar and water, heated until dissolved) before serving.
Uneven Baking
Hot spots in your oven can cause uneven browning. Rotate the cake pan midway through baking (after 25 minutes) by swapping the top and bottom racks. If your oven runs hot, tent the cake with aluminum foil after 30 minutes to prevent over-browning on top. For extra insurance, bake on the middle rack where heat is most even. A thermometer confirms your oven's accuracy—most home ovens run 25°F hotter than set.
No Caramelized Top
The secret to that perfect caramelized crust is the final 5 minutes at 375°F. If your top isn't browning enough, try these fixes: brush the top with 1 teaspoon melted butter before the final temperature increase, or sprinkle 1 tablespoon brown sugar on top during the last 10 minutes of baking. For a deeper color, increase the oven to 375°F for the last 7-8 minutes instead of 5.
Splenda Clumping
Splenda tends to clump when mixed with wet ingredients. To prevent this, sift the 1.5 cups Splenda with the dry ingredients before adding to the wet mixture. If clumps form during mixing, press them through a fine-mesh sieve or whisk vigorously to dissolve. For extra insurance, mix the Splenda with the 2 cups flour before adding to the batter. This ensures even distribution throughout the cake. 💡

Frequently asked questions
Can I substitute Splenda with another sweetener?
Yes! For a 1:1 substitution, use white sugar or honey. However, Splenda's moisture-retaining properties create that signature tender texture. If using honey, reduce other liquids by 2 tablespoons to maintain balance. For lower glycemic options, try erythritol or monk fruit sweetener, but expect slightly different texture results.
How do I know when my bananas are ripe enough?
Look for bananas with dark brown spots covering most of the peel—that's peak ripeness! The skin should also yield slightly when pressed. Overripe bananas (black peel) work too, but they may make the cake slightly denser. For best flavor, use bananas that are soft enough to mash easily but not mushy.
Why does my cake sometimes crack on top?
Cracking usually happens when the cake bakes too quickly or the oven runs hot. To prevent this, bake at 350°F for the first 35 minutes, then increase to 375°F for the final 5 minutes to develop the caramelized top. Also ensure your oven is properly calibrated—most home ovens run 25°F hotter than set.
Can I make this cake gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill). For best results, add ½ teaspoon xanthan gum to help bind the cake. You may need to increase the baking time by 5-10 minutes as gluten-free cakes often bake slower.
How should I store leftovers?
Wrap cooled cake tightly in plastic wrap and store at room temperature for up to 3 days. For longer storage, refrigerate for 5 days or freeze slices for 3 months. To revive, microwave for 10-15 seconds—the caramelized top will soften slightly but the moist layers stay perfect!
