Instructions:

1. Preheat and Prepare Pans:
- Preheat your oven to 350°F (175°C).
- Grease and flour two 8-inch round cake pans, or line with parchment paper.
2. Cream Butter and Sugar:
- In a large mixing bowl, cream together the softened butter and sugar until light and fluffy. This should take about 3-4 minutes with an electric mixer.
3. Add Eggs and Vanilla:
- Beat in the eggs, one at a time, ensuring each is fully incorporated before adding the next.
- Add the vanilla extract and mix until combined.
4. Incorporate Chocolate and Cocoa:
- Melt the dark chocolate in a heatproof bowl over simmering water or in the microwave in short bursts, stirring frequently.
- Add the melted chocolate and dry cocoa powder to the batter and mix until fully combined.
5. Mix in Flour and Buttermilk:
- Alternately add the self-raising flour and buttermilk to the chocolate mixture, starting and ending with the flour. Mix each addition until just combined. Be careful not to overmix at this stage.
6. Bake the Cake:
- Divide the batter evenly between the prepared cake pans.
- Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
- Allow the cakes to cool in the pans for 10 minutes, then remove from the pans and transfer to a wire rack to cool completely.
7. Prepare the Frosting:
- In a medium bowl, beat the peanut butter and powdered sugar together until smooth and creamy.
- Melt the milk chocolate in a heatproof bowl over simmering water or in the microwave in short bursts, stirring frequently.
- In a small saucepan, heat the heavy whipping cream just until it begins to simmer, then pour it over the melted milk chocolate, stirring until smooth and glossy.
- Combine the peanut butter mixture with the chocolate mixture, and beat until fully incorporated and smooth.
8. Assemble the Cake:
- Place one cake layer on a serving plate or cake stand.
- Spread a generous layer of frosting on top.
- Place the second cake layer on top of the first and frost the top and sides with the remaining frosting.
9. Decorate and Serve:
- Optionally, garnish with chocolate shavings, sprinkles, or a drizzle of melted chocolate.
- Slice and serve this rich, decadent peanut butter and chocolate cake.

Peanut butter and chocolate cake FAQ:

What's the baking time for the cake?

Bake the peanut butter and chocolate cake in a preheated oven at 350°F (175°C) for 25-30 minutes. To check for doneness, insert a toothpick into the center; it should come out clean.

How should I store leftover cake?

Store any leftover cake in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate, where it can last up to a week. You can also freeze slices for up to 3 months.

Can I use different types of flour instead of self-raising flour?

Yes, you can substitute self-raising flour with all-purpose flour, but add 1.5 teaspoons of baking powder for every cup used to achieve the same rise.

What can I use as a substitute for buttermilk?

If you don't have buttermilk, you can make a substitute by mixing 1 cup of milk with 1 tablespoon of vinegar or lemon juice. Let it sit for about 5 minutes before using.

What chocolate options can I use for this recipe?

You can replace dark chocolate with semi-sweet chocolate or bittersweet chocolate for a similar flavor profile. For milk chocolate, you can also use white chocolate if you prefer a sweeter frosting.

Tips:

- Make sure all your ingredients are at room temperature before you start. This ensures a smooth batter and even baking.

- For an extra layer of flavor, you can add a teaspoon of instant coffee granules to enhance the chocolate taste.

- When melting the chocolate, do it slowly using a double boiler or in short bursts in the microwave to avoid scorching.

- Allow the cake to cool completely before frosting to prevent the frosting from melting and sliding off.

- For a more intense peanut butter flavor, you can also add peanut butter chips to the batter before baking.

- Store leftovers in an airtight container at room temperature for up to three days or in the refrigerator for up to a week.
