This Baileys Irish Cream Cake delivers the rich, boozy depth of your favorite Irish cream in every moist, velvety bite—all made from scratch with a buttery streusel crown that cracks open to reveal layers of indulgence. 💛 The secret lies in blending the liqueur directly into the batter, ensuring the alcohol infuses evenly without overpowering the tender crumb. I've perfected this recipe after years of testing, balancing the cake's density with just enough structure to hold up to the boozy filling.
The magic happens in two key techniques: first, using sour cream and buttermilk to create an impossibly tender crumb, and second, baking the cake in a single layer before assembling with a luscious Baileys buttercream. This approach guarantees moist layers that stay rich and flavorful even after cooling. The streusel topping adds a delightful textural contrast, with its crispy edges and soft centers that melt into the cake.
By the time you slice into this cake, you'll be rewarded with a perfect balance of sweet, creamy, and boozy flavors—each forkful delivering that signature Irish cream taste you love, but with the homemade quality that makes it truly special. The buttercream isn't just sweet; it's infused with Baileys essence, tying every component together in a cohesive, restaurant-worthy dessert.
Whether you're celebrating a birthday, holiday gathering, or just craving a decadent treat, this cake is designed to impress without requiring advanced baking skills. The recipe includes step-by-step guidance for layering, cooling, and decorating, ensuring even first-time bakers achieve professional results. Let's get started on this showstopping dessert!
Ingredients for baileys irish cream cake recipe from scratch
The secret to this decadent cake lies in blending Baileys directly into the batter for even boozy moisture.
| Ingredient | Amount | Notes |
|---|---|---|
| Baileys Irish Cream Liqueur 🍷 | ¾ cup | High-quality, not imitation |
| All-Purpose Flour 🌾 | 3 cups | Sifted for lightness |
| Granulated Sugar 🍚 | 2 ½ cups | Superfine preferred |
| Unsalted Butter 🧈 | 1 ½ cups | Room temperature, full-fat |
| Large Eggs 🥚 | 4 whole | Room temperature |
| Sour Cream 🥛 | 1 cup | Full-fat for richness |
| Buttermilk 🥛 | 1 cup | Fresh, not powdered |
| Vanilla Extract 🌿 | 2 tsp | Pure, not imitation |
| Baking Powder 🧂 | 2 tsp | Aluminum-free |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Old-Fashioned Oats 🌾 | 1 ½ cups | Quick or rolled |
| Light Brown Sugar 🍚 | ¾ cup | Packed, not granulated |
| Chopped Walnuts 🥜 | ½ cup | Toasted for depth |

Baileys is the star here—avoid imitations like the plague. Trader Joe's and Whole Foods carry the real stuff, and it's worth the splurge for this recipe. The buttercream gets an extra infusion of Baileys essence, so don't skimp on the liqueur. For the cake batter, room-temperature eggs and butter are non-negotiable—they create that signature tender crumb. If you're in a pinch, microwave the butter 40 seconds to just melt it, then cool. The oats should be old-fashioned, not quick—they add that perfect chew to the streusel.
No Baileys? Irish whiskey or vanilla vodka can substitute at half the amount, but the flavor won't be identical. For the streusel, pecans or almonds work if walnuts aren't available, though the texture will differ slightly. The buttercream can be made ahead and stored in the fridge for up to 3 days, just re-whip before using. If you're concerned about the cake being too moist, reduce the buttermilk by 2 tbsp—it's the secret to that velvety texture. The powdered sugar should be sifted before mixing to avoid lumps in the buttercream.
This cake keeps beautifully—3 days at room temperature covered with plastic wrap, or up to 1 week refrigerated. For longer storage, freeze the fully assembled cake (without frosting) for up to 3 months. Let it thaw overnight in the fridge before frosting. The streusel topping can be made a day ahead and stored in an airtight container—it actually tastes better after resting. If you're making this for a crowd, bake the cake 2 days ahead; the flavors deepen as it sits.

Step-by-step instructions for Baileys Irish cream cake
Here's how to create a decadently moist cake with a boozy twist and buttery streusel crown.
👨🍳 Step 1: Prepare the Cake Batter with Baileys Infusion
Preheat your oven to 350°F and grease two 9-inch round cake pans. In a large mixing bowl, combine the 1.5 cups unsalted butter and 2.5 cups granulated sugar. Beat with an electric mixer on medium-high speed for 3-4 minutes until light and fluffy, scraping down the sides as needed.
Add the 4 whole large eggs, one at a time, mixing well after each addition. In a separate bowl, whisk together the 3 cups all-purpose flour, 2 tsp baking powder, 0.5 tsp salt, and 1 tsp cinnamon. With the mixer on low speed, add about one-third of the flour mixture to the butter mixture, then alternate with the 1 cup buttermilk, 1 cup sour cream, and 2 tsp vanilla extract, ending with the remaining flour mixture. Mix just until combined.
Pour in the 0.75 cup Baileys Irish Cream Liqueur and mix gently until just incorporated. The batter should be thick but pourable. Divide the batter evenly between the prepared pans and smooth the tops with a spatula. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
🥘 Step 2: Make the Streusel Topping
In a medium bowl, combine the 1.5 cups old-fashioned oats, 0.75 cup light brown sugar, 0.5 cup chopped walnuts, 0.5 tsp salt, and 1 tsp cinnamon. Cut in the 0.5 cups unsalted butter (reserved from the cake batter) using a pastry cutter or your fingers until the mixture resembles coarse crumbs with some pea-sized butter pieces remaining. This texture ensures a perfect balance of crunch and creaminess.
Sprinkle the streusel mixture evenly over the cooled cake layers. For extra richness, you can brush the tops of the cakes with a thin layer of Baileys liqueur before adding the streusel. Return the cakes to the oven and bake for an additional 10-12 minutes until the streusel is golden brown and crispy. Let the cakes cool completely before assembling.
🍳 Step 3: Prepare the Baileys Buttercream
In a large mixing bowl, beat the 1.5 cups heavy whipping cream with an electric mixer on medium-high speed until soft peaks form. Gradually add the 3 cups powdered sugar, mixing on low speed until combined. Increase the speed to medium-high and beat for 2-3 minutes until the buttercream is smooth, thick, and holds stiff peaks.
Add the 0.25 cup Baileys Irish Cream Liqueur (reserved from the original amount) and 1 tsp vanilla extract, mixing on low speed until fully incorporated. The buttercream should be light and airy, with a subtle boozy aroma that complements the cake beautifully. If the buttercream is too thick, add 1-2 tablespoons milk or Baileys liqueur to reach your desired consistency.
🥘 Step 4: Assemble and Decorate the Cake
Place one cake layer on a cake stand or plate. Spread a generous layer of the Baileys buttercream over the top, leaving a ½-inch border around the edges. Repeat with the second cake layer. Crumb coat the entire cake with a thin layer of buttercream, then chill in the refrigerator for 15-20 minutes to firm up.
Once chilled, apply the final layer of buttercream, creating smooth sides and a slightly domed top. Use a spatula to create texture or swirls for a decorative finish. For added flair, press additional streusel topping onto the sides of the cake or create a crown around the top. Chill the cake in the refrigerator for at least 1 hour before slicing to allow the flavors to meld and the buttercream to set.
Pro Tips For Making Baileys Irish Cream Cake Recipe From Scratch
- Whisk Eggs Room-Temp: Cold eggs won’t blend smoothly into the batter, and you’ll end up with lumps that ruin the texture. Pop them in a bowl of warm water for 5 minutes first—trust me, the difference in creaminess is noticeable.
- Measure Baileys Precisely: That bottle’s pour spout lies—don’t eyeball it. Use a small measuring cup or kitchen scale (1 oz = 30ml) to avoid overpowering the cake with boozy bitterness. Too much, and your cake tastes like a drink, not dessert.
- Cream Butter Slowly: Dump cold butter into sugar and beat like crazy? You’ll end up with a grainy mess. Let the butter sit at room temp for 30 minutes first, then beat on medium until just combined—no need to overwork it. The goal is smooth, not tired.
- Bake Until Springy: The cake’s done when it bounces back when pressed, not when the timer dings. Overbaking dries it out; underbaking leaves it gummy. Pull it at 325°F (163°C) internal temp, then tent with foil if it’s browning too fast.
Regional styles of this recipe
Irish Pub Classics
This cake brings the cozy, boozy vibes of an Irish pub straight to your kitchen. In Dublin and Galway, you’ll often find Baileys served in coffee or as a dessert topper, but this recipe elevates it to center stage. The rich, creamy texture mirrors the indulgence of a traditional Irish cream trifle—a dessert staple in pubs across the Emerald Isle. The streusel crown adds a rustic touch, reminiscent of Irish soda bread crumble often served with afternoon tea. 💛
American Boozy Twist
While the Irish version leans into coffee pairings, American adaptations often serve this cake alongside whiskey sodas or Irish stout floats. The key difference? American bakers tend to use more butter in the streusel for extra richness, while Irish recipes might incorporate a pinch of black pepper to balance the sweetness. I’ve kept it classic but added a touch of toasted walnuts for that American-style crunch.
Canadian Maple Fusion
Up north, this cake gets a maple syrup glaze drizzle, blending the creamy Baileys with Canada’s signature sweetness. Simply whisk ½ cup maple syrup with 2 tbsp heavy cream and brush it over the cooled cake layers before adding the buttercream. The maple adds a caramel-like depth that pairs perfectly with the boozy notes—like a Canadian whiskey cake meets Irish cream.
British Tea Party Adaptation
For a British twist, serve this cake with Earl Grey-infused buttercream instead of plain. Steep 1 Earl Grey tea bag in ¼ cup warm milk for 5 minutes, then strain and mix it into the buttercream. The bergamot notes complement the Baileys beautifully, making it a showstopper for afternoon tea gatherings. A sprinkle of edible gold leaf on top adds that quintessential British touch.
Australian Summer Version
Down under, this cake becomes a lightened-up summer dessert by swapping the streusel for a coconut crumble (use 1 cup desiccated coconut instead of oats). The tropical vibe pairs wonderfully with Baileys-infused sorbet on the side. For extra freshness, top with mango slices and a lime zest garnish—perfect for beachside picnics or BBQs.
German Coffeehouse Style
In German cafés, this cake might be served with Kaffee und Kuchen (coffee and cake) by adding a dark chocolate ganache between the layers. Melt 8 oz dark chocolate with ½ cup heavy cream, then cool slightly before spreading between cake layers. The contrast of bitter chocolate and creamy Baileys is a match made in dessert heaven—ideal for cozy winter gatherings. 🌟

Frequently asked questions
Can I substitute Baileys with another liqueur?
Yes, but the flavor will differ. For a similar creamy profile, use 1/2 cup Irish whiskey or vanilla vodka instead of the full 0.75 cup Baileys. The alcohol content will be higher, so reduce other liquids slightly (like buttermilk) to maintain moisture balance. For a coffee twist, try Kahlúa at the same amount—it pairs beautifully with the cake's buttery richness.
Why does my cake turn out dense instead of moist?
Overmixing the batter or skipping the room-temperature ingredients are common culprits. Use a rubber spatula to gently fold the flour mixture, and beat the butter and sugar for exactly 3-4 minutes—no longer! Also, ensure your eggs and butter are truly room temp (they should indent when pressed). For extra moisture, brush the cooled layers with 1 tbsp Baileys before frosting.
How do I make this cake ahead of time?
Bake the cake layers 2 days ahead and store them in an airtight container at room temperature. The streusel can be prepped 1 day ahead and kept in the fridge. Assemble the cake 4-6 hours before serving—this lets the flavors meld beautifully. If storing longer than 3 days, freeze the fully assembled cake (without frosting) for up to 3 months. Thaw overnight in the fridge.
Can I make this cake in a single layer instead of two?
Use a 9x13-inch pan and bake for 35-40 minutes at 350°F. For a dome shape, bake in a 10-inch springform pan for 40-45 minutes. The streusel will need 15 extra minutes to crisp. Just adjust the buttercream quantity to 2 cups instead of 3, and spread it evenly over the top before adding the streusel crown.
What's the best way to serve this cake?
Slice it chilled for cleaner pieces, but serve at room temperature for the best flavor experience. Pair with a steaming cup of coffee or a cold glass of milk to balance the boozy richness. For a dramatic presentation, dust the top with powdered sugar or garnish with fresh berries. The cake also makes a stunning centerpiece when decorated with gold leaf or a drizzle of caramel.
