Ingredients for Chocolate Peanut Caramel Cake

Chocolate Cake

• 120 g all-purpose flour
• 45 g unsweetened cocoa powder
• 150 g granulated sugar
• 50 g brown sugar
• 1/2 tsp baking powder
• 1/2 tsp baking soda
• 1/2 tsp salt
• 1 large egg
• 80 ml buttermilk
• 60 ml vegetable oil
• 1 tsp vanilla extract
• 100 ml hot coffee

Chocolate Filling

• 200 g semi-sweet chocolate
• 150 ml heavy cream
• 30 g unsalted butter
• 1 tbsp smooth peanut butter
• 1 tsp vanilla extract
• Pinch of salt

Peanut Caramel Filling

• 150 g roasted peanuts, roughly chopped
• 120 g sweetened condensed milk
• 80 g brown sugar
• 50 g unsalted butter
• 60 ml heavy cream
• 2 tbsp smooth peanut butter
• 1/2 tsp vanilla extract
• 1/4 tsp salt

Caramelized Peanut Topping

• 200 g roasted peanuts, roughly chopped

Ingredient tips: If you do not have buttermilk, mix 80 ml milk with 1 teaspoon lemon juice or white vinegar and let it sit for 5 minutes. For a dairy-free version, use coconut cream and vegan butter. A 1:1 gluten-free flour blend works well in the chocolate cake.

How to Make Chocolate Peanut Caramel Cake

Make the Chocolate Cake

1. Preheat the oven to 175°C / 350°F. Grease and line an 8-inch round cake pan.
2. In a large bowl, whisk together the flour, cocoa powder, granulated sugar, brown sugar, baking powder, baking soda, and salt.
3. Add the egg, buttermilk, vegetable oil, and vanilla extract. Mix until smooth.
4. Pour in the hot coffee gradually while stirring. The batter will be thin, which is normal.
5. Pour the batter into the prepared pan. Bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean.
6. Cool in the pan for 10 minutes, then transfer to a wire rack. Cool completely before slicing into two layers.

Tip: Hot coffee deepens the chocolate flavor without making the cake taste like coffee.

Make the Chocolate Filling

1. Heat the heavy cream until just hot, not boiling.
2. Place the semi-sweet chocolate in a heatproof bowl. Pour the hot cream over the chocolate and let it sit for 2 minutes.
3. Stir gently until smooth.
4. Add the butter, peanut butter, vanilla extract, and salt. Stir until glossy.
5. Let the filling cool at room temperature until thick and spreadable.

Make the Peanut Caramel Filling

1. Melt the butter and brown sugar together in a saucepan over medium heat.
2. Add the condensed milk and heavy cream. Cook over low-medium heat, stirring constantly, until thick and glossy.
3. Remove from heat. Stir in the peanut butter, vanilla extract, and salt.
4. Fold in the roughly chopped roasted peanuts. Let the mixture cool slightly before assembling.

Assemble the Cake

1. Place one chocolate cake layer on a serving plate or cake board.
2. Spread a generous layer of chocolate filling over the top.
3. Add the peanut caramel mixture evenly, pressing gently.
4. Place the second cake layer on top.
5. Cover the top with another layer of chocolate filling.

Make the Caramelized Peanut Topping

1. In a clean saucepan, caramelize the granulated sugar over medium heat until golden. Swirl the pan instead of stirring too much.
2. Carefully add the butter and heavy cream. The mixture will bubble.
3. Add a pinch of salt and stir until smooth.
4. Stir in the chopped peanuts immediately.
5. Spread the warm topping over the cake quickly before it sets.

Refrigerate the assembled cake for at least 4 hours, preferably overnight.

Preparation Time

• Prep time: 40 minutes
• Cook time: 30 minutes
• Chilling time: 4 hours minimum
• Total time: 5 hours 10 minutes including chilling

Active work is under 1.5 hours, similar to many layer cakes, but the chilling time does the heavy lifting.

Healthier Alternatives

• Replace all-purpose flour with a 1:1 gluten-free flour blend.
• Use coconut cream instead of heavy cream for a dairy-free version.
• Swap butter for vegan butter or coconut oil.
• Choose dark chocolate with at least 70 percent cocoa to reduce sweetness.
• Use unsalted natural peanut butter to control sodium.
• Reduce the sugar in the caramel by up to 20 percent for a less sweet finish.

For a vegan version, replace the egg with a flax egg, use plant milk mixed with vinegar instead of buttermilk, and use coconut condensed milk.

Serving Suggestions

• Serve chilled slices with a sprinkle of flaky sea salt.
• Add a scoop of vanilla bean ice cream or whipped cream.
• Pair with espresso, black coffee, or a glass of cold milk.
• For a dessert board, cut into small squares and serve with fresh raspberries.
• Warm slices slightly for a softer caramel texture.

Common Mistakes to Avoid

• Overbaking the chocolate cake makes it dry. Check at 25 minutes.
• Slicing warm cake layers can cause crumbling. Cool completely first.
• Boiling the cream for the chocolate filling can split the ganache. Heat until just hot.
• Rushing the caramel can burn the sugar. Use medium heat and watch closely.
• Spreading the caramelized peanut topping too slowly allows it to harden. Work quickly.
• Skipping the chilling time makes slicing messy. Refrigerate at least 4 hours.

Storage Tips

• Refrigerate covered for up to 5 days.
• Freeze the whole cake or individual slices wrapped tightly for up to 2 months.
• Thaw frozen cake in the refrigerator overnight.
• To serve warm, microwave individual slices for 10 to 15 seconds.
• Do not leave the cake at room temperature for more than 2 hours because of the cream filling.
