Ingredients

Chocolate Cake

• 3 cups all-purpose flour
• 3 cups granulated sugar
• 1½ cups special dark cocoa powder
• ½ cup unsweetened cocoa powder
• 1 tbsp baking powder
• 1½ tsp baking soda
• 1½ tsp kosher salt
• 4 large eggs
• ½ cup sour cream
• 1 cup buttermilk
• 1 cup warm water
• ½ cup non-alcoholic Kahlua substitute (coffee-flavored syrup or halal coffee liqueur alternative)
• ½ tsp espresso powder
• ½ cup canola oil
• 1 tbsp pure vanilla extract

Strawberry Buttercream Frosting

• 2 cups unsalted butter (softened)
• 6 cups powdered sugar
• 4 tsp vanilla extract
• ½ cup finely diced strawberries (very dry)
• 5-7 tbsp heavy whipping cream

Chocolate Ganache

• 1 cup semi-sweet chocolate chips
• ½ cup heavy whipping cream

For Decorating

• Fresh strawberries
• Large piping bag with star tip
• Ice cream scoop

Instructions

1. Prep the pans & liquids: Preheat your oven to 350°F (175°C). Spray three 9-inch cake pans with non-stick spray or grease and lightly flour them. In a small bowl, whisk together warm water, the non-alcoholic Kahlua substitute, and espresso powder until completely dissolved.
2. Mix the dry ingredients: In the bowl of a stand mixer, whisk together the all-purpose flour, granulated sugar, both cocoa powders, baking powder, baking soda, and kosher salt until everything is well combined and uniform.
3. Build the batter: Gradually add in the eggs, sour cream, buttermilk, espresso mixture (water-Kahlua-espresso), canola oil, and vanilla extract. Mix on medium speed until the batter is smooth, creamy, and free of lumps. Take your time to ensure everything is fully incorporated.
4. Divide and bake the cakes: Evenly pour the batter into the prepared cake pans, smoothing the tops with a spatula. Bake for 25-35 minutes, or until a toothpick inserted into the center comes out clean. Remove from oven and let cool in the pans for 20 minutes before turning out onto wire racks to cool completely.
5. Prepare the strawberry buttercream: Pat the diced strawberries very dry using paper towels to avoid excess moisture. In a large mixing bowl, beat softened butter on medium speed until creamy. Add vanilla extract, powdered sugar, strawberries, and 5 tablespoons of heavy whipping cream. Beat until thick and fluffy, about 3-5 minutes. If needed, add 1-2 more tablespoons of cream to reach your desired consistency. Beat an extra 2-3 minutes for a light, whipped texture. Scoop 1 cup of this frosting into your piping bag and set aside.
6. Assemble the cake: Place one cake layer on a serving board or plate. Add 4-6 scoops of frosting on top and smooth evenly. Repeat the process with the second layer. Place the final cake layer on top and use the remaining buttercream to frost the entire cake smoothly.
7. Make the chocolate ganache: Heat heavy cream in a small saucepan over medium heat just until steaming (do not boil). Pour the hot cream over the semi-sweet chocolate chips in a heatproof bowl. Let it rest for one minute, then whisk until the ganache is smooth and shiny. Transfer the ganache to a squeeze bottle or piping bag.
8. Decorate & finish: Carefully pipe decorative ganache drips around the edges of the cake. Use the reserved piping bag to add pretty frosting dollops on top. Garnish by nestling fresh strawberries into the buttercream dollops for a fresh and striking presentation. Chill the cake slightly before serving for best results.

Pro Tips for Perfect Results

• Use room temperature ingredients: For even mixing and smooth batter, bring eggs, butter, sour cream, and buttermilk to room temperature before starting.
• Don't skip drying strawberries: Excess moisture from berries can thin out your frosting. Patting them dry ensures a stable, creamy buttercream.
• Check your oven temperature: An accurate oven ensures the cake bakes evenly without drying out.
• Level your cake layers: Trim any domed tops to create flat layers. This helps keep your cake stable and professional looking when stacking.
• Chill your cake before ganache: Cooling the frosted cake slightly allows the ganache to set nicely without sliding off.

Variations and Substitutions

• Kahlua substitute: Replace the non-alcoholic Kahlua alternative with strong brewed coffee or coffee extract for a similar flavor.
• Dairy-free version: Use vegan butter and a plant-based cream substitute for the buttercream and ganache.
• Healthier swaps: Substitute half the all-purpose flour with whole wheat flour for added fiber or use coconut sugar instead of granulated sugar for a lower glycemic index.
• Fruit swaps: Replace strawberries in the buttercream with raspberries or blueberries for a different fruity flair.

Storage and Reheating Tips

Store this cake covered in an airtight container or cake dome at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days. If refrigerated, let the cake sit at room temperature for about 30 minutes before serving to soften the buttercream and ganache.

To reheat individual slices, use a microwave on low power for 10-15 seconds to gently warm without melting the frosting. Avoid reheating the whole cake as it may cause frosting to melt or separate.

Frequently Asked Questions

Can I make this cake ahead of time?

Absolutely! You can bake the cake layers 1-2 days in advance and wrap them tightly in plastic wrap. Store the assembled, frosted cake in the refrigerator and bring to room temperature before serving.

What if I don’t have espresso powder?

Espresso powder enhances the chocolate flavor but you can omit it or substitute with 1 teaspoon of instant coffee granules diluted in warm water.

How do I keep the cake moist?

Using buttermilk, sour cream, and the coffee-flavored liquid helps retain moisture. Avoid overbaking and ensure to cool cakes properly before frosting.

Can I freeze this cake?

Yes, freeze individual unfrosted cake layers wrapped tightly in plastic and aluminum foil for up to 3 months. Thaw layers fully before frosting and assembling.

Is this recipe kid-friendly?

Yes! Since we use a non-alcoholic Kahlua substitute, this cake is suitable for all ages and tastes great with or without the coffee flavor.
