Instructions

1. 1
   Preparation: Preheat your oven to 350°F (177°C). Grease three 9-inch cake pans, line the bottoms with parchment paper rounds, and grease the parchment paper itself to ensure the cakes release seamlessly.
2. 2
   Mix Dry Ingredients: Combine and whisk the flour, cocoa powder, sugar, baking soda, baking powder, salt, and optional espresso powder together in a large mixing bowl. Set aside.
3. 3
   Mix Wet Ingredients: In a separate bowl or using a mixer fitted with a whisk attachment, beat the oil, room-temperature eggs, and sour cream together on medium-high speed until blended. Add the buttermilk and vanilla extract, beating until combined.
4. 4
   Combine & Fold: Pour the wet ingredients into the dry mixture, add the hot water or black coffee, and blend on low speed until the cake batter is completely uniform. Gently fold in the flour-coated mini chocolate chips. The batter will be thin with a few surface air bubbles.
5. 5
   Bake the Cakes: Divide the batter evenly among your 3 prepared cake pans (about 6–6.5 cups total). Bake for 24–26 minutes, or until a toothpick inserted into the center comes out clean. Cool the cakes inside their pans on a wire rack for 1 hour. Run a knife around the edges to loosen, invert to remove from pans, peel off the parchment, and leave on the rack to cool completely.
6. 6
   Make the Peanut Butter Frosting: Whip the softened butter on medium-high speed for roughly 2 minutes until light and smooth. Incorporate the creamy peanut butter, beating until fully combined. Lower the mixer speed and add the confectioners’ sugar, vanilla, salt, and heavy cream. Once added, increase to medium-high and beat for 1–2 minutes until smooth and creamy. (Add up to 1/4 cup extra confectioners' sugar if it feels too thin).
7. 7
   Assemble and Crumb Coat: Set your first cake layer onto a serving plate or stand. Spread about 1 cup of peanut butter frosting evenly over the top. Add the second layer, frost, and top with the third layer. Apply a very thin layer of frosting over the top and outer sides of the entire cake to form a crumb coat. Smooth with a bench scraper and refrigerate uncovered for 30 minutes to 3 hours to lock in the crumbs.
8. 8
   Make the Chocolate Ganache: Place your finely chopped semi-sweet chocolate into a medium heat-proof bowl. In a small saucepan, bring the heavy cream to a gentle simmer over medium heat (do not boil). Pour the hot cream over the chocolate and let it sit for 2–3 minutes to soften. Slowly stir with a spoon or spatula until completely melted and glossy. Place the ganache in the fridge for 30 to 60 minutes to thicken slightly.
9. 9
   Decorate & Chill: Pour or spoon the thickened ganache over the chilled cake. Smooth the surfaces with an icing spatula or bench scraper. If desired, use a piping bag with a Wilton 1M tip to pipe the remaining peanut butter frosting around the top edge and decorate with mini peanut butter cups. Serve immediately or chill uncovered for up to 4–6 hours before presentation.
10. 10
    Storage: Wrap any leftover cake tightly or store in a cake carrier in the refrigerator for up to 5 days. Allow to come to room temperature before serving if desired.

Frequently Asked Questions

Can I make this Dark Chocolate Peanut Butter Cake ahead of time? Absolutely! You can bake the chocolate cake layers a day in advance. Once they are completely cool, wrap them tightly in plastic wrap and store them at room temperature. You can also make the frosting ahead of time and store it in the fridge; just let it come to room temperature and give it a quick whip before assembling.

Why do you coat the mini chocolate chips in flour before adding them to the batter? Tossing the mini chocolate chips in a tablespoon of flour prevents them from sinking straight to the bottom of your cake pans while baking. This clever trick ensures you get delicious chocolate pockets throughout every single bite of the cake.

What type of peanut butter works best for the frosting? Standard, commercial creamy peanut butter (like Jif or Skippy) works best for this recipe. Natural style peanut butters that require stirring contain too much oil separation and can cause your peanut butter frosting to split or become too runny.

Can I substitute the espresso powder in the cake layers? Yes! The espresso powder is entirely optional and does not make the cake taste like coffee; it simply intensifies the rich notes of the dark cocoa powder. If you prefer to omit it, you can just leave it out or use plain hot water instead of hot black coffee.
