Let’s Bake This Beauty!
Step 1: Prepare the Cake
Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans. Line the bottoms with parchment paper for easy removal. Trust me, future-you will be thankful.
Step 2: Mix the Dry Ingredients
In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt. The smell of cocoa already? Yes, please.
Step 3: Add the Wet Ingredients
Add in the milk, oil, eggs, and vanilla. Beat until the mixture is smooth and creamy. Now, slowly stir in that cup of boiling water—this is the secret to a super moist, tender cake. Don’t worry if the batter seems thin; that’s exactly how it should be.
Step 4: Bake to Perfection
Divide the batter evenly between the pans and bake for 30–35 minutes, or until a toothpick comes out clean. Let the cakes cool in the pans for 10 minutes before transferring to a wire rack. Completely cooled layers make for easier assembly.
Step 5: Peanut Butter Heaven
While the cakes cool, make your filling. Beat peanut butter and softened butter until creamy and smooth. Gradually add powdered sugar and a splash of heavy cream. Whip it until it’s light, fluffy, and dangerously delicious.
Step 6: The Ganache Glow-Up
Heat the cream until it’s just about to simmer, then pour it over the chocolate chips. Let it sit for 5 minutes, then stir until you get a glossy, velvety ganache. It’s pure chocolate magic.
Step 7: Assemble Like a Pro
Place one cake layer on a plate or cake stand. Spread a thick layer of peanut butter filling on top. Add the second cake layer and gently press down. Now for the showstopper: pour that luscious ganache over the top, letting it drip naturally down the sides.
Step 8: Time to Devour!
Let the ganache set slightly, then slice into your masterpiece. Whether you’re serving this at a party, sharing with friends, or just treating yourself (no judgment!), one bite will convince you—this is not just a cake, it’s an experience.
Pro Tip: Store any leftovers (if there are any) in the fridge. It gets even better the next day.
