How to Make Decadent Peanut Butter Layer Cake Recipe for True Peanut Lovers – BeRecipe

Follow these simple steps to prepare this delicious dish:

Step 1: Preheat Your Oven

Preheat your oven to 350°F (175°C). Grab two round cake pans and grease them well with non-stick spray or butter.

Step 2: Prepare Your Dry Ingredients

In a large mixing bowl, whisk together all-purpose flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt until well combined.

Step 3: Mix Wet Ingredients

In another bowl, combine eggs, milk, vegetable oil, and vanilla extract. Whisk until blended smoothly.

Step 4: Combine Everything

Pour the wet ingredients into the dry ingredients and mix until just combined. Do not overmix; we want fluffy layers!

Step 5: Bake

Divide the batter evenly between the prepared pans. Bake in preheated oven for about 30-35 minutes or until a toothpick inserted comes out clean.

Step 6: Cool & Frost

Allow cakes to cool in pans for about ten minutes before transferring them onto wire racks. Once completely cooled, whip up your peanut butter frosting by beating together softened unsalted butter and peanut butter until creamy. Gradually add powdered sugar and heavy cream until you reach desired consistency.

Transfer one layer onto your serving plate and spread a generous layer of frosting on top; repeat with second layer. Frost the top and sides of the cake generously.

Now step back and admire your creation! Slice into it to reveal those beautiful layers; serve immediately because trust me—everyone will want seconds!
