Instructions

Let’s get baking!

1. Preheat Your Oven

Start by preheating your oven to 350°F (175°C). Grease and flour your cake pan or line it with parchment paper to ensure your cake comes out easily after baking.

2. Make the Cake Batter

In a large bowl, cream together the softened butter and sugar until light and fluffy. This will take about 2-3 minutes using a hand mixer or stand mixer. Add the eggs, one at a time, beating well after each addition. Stir in the vanilla extract.

In a separate bowl, whisk together the flour, cacao powder, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, alternating with the milk, until everything is well combined. The batter should be smooth and slightly thick.

3. Prepare the Peanut Butter Swirl

In a microwave-safe bowl, warm the peanut butter for about 20-30 seconds to make it easier to swirl. You want it to be runny but not too hot. If it’s a little thick, you can also stir in a spoonful of milk to loosen it up.

4. Layer the Cake Batter

Spoon half of the cake batter into the prepared pan, spreading it out evenly. Then, spoon a few dollops of peanut butter on top of the batter, and gently swirl it with a knife or skewer to create a beautiful marbled effect. Add the remaining cake batter on top and repeat the swirling process with the rest of the peanut butter.

5. Bake to Perfection

Bake the cake for about 35-40 minutes, or until a toothpick inserted into the center comes out clean. Every oven is a little different, so keep an eye on it towards the end to make sure it doesn’t overbake.

6. Cool and Serve

Let the cake cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely. Once it’s cool, slice and enjoy the beautiful peanut butter and cacao swirls!

How to Serve Cacao and Peanut Swirl Cake

While this cake is delicious on its own, here are a few ways to take it to the next level:

With a Scoop of Ice Cream: A scoop of vanilla or chocolate ice cream makes the perfect creamy pairing to this moist, nutty cake.
Dusted with Powdered Sugar: A light dusting of powdered sugar on top of the cake adds a beautiful, finishing touch.

With Whipped Cream: A dollop of freshly whipped cream balances out the richness of the cake and adds a lovely touch of sweetness.
As a Layer Cake: For an extra special treat, bake this cake in two layers and add a peanut butter frosting in between for a show-stopping layer cake.

Additional Tips

Peanut Butter Tip: Make sure to use creamy peanut butter for the best swirling effect. Crunchy peanut butter can be used, but it will disrupt the swirl and create chunks instead of smooth lines.

Mixing Variations: Feel free to get creative with the mix-ins. You could add chocolate chips, chopped peanuts, or even a drizzle of caramel over the top for a little extra indulgence.
Storage Tips: Store any leftover cake in an airtight container at room temperature for up to 3 days. It also keeps well in the fridge if you want to extend its freshness.
Freezing: This cake freezes beautifully! Wrap individual slices tightly in plastic wrap, and freeze for up to 2 months. When you’re ready to eat, just let it thaw at room temperature.
