Ingredients for Decadent Peanut Butter Layer Cake Recipe for True Peanut Lovers – BeRecipe

Here’s what you’ll need to make this delicious dish:

All-Purpose Flour: The backbone of any cake, choose unbleached flour for a softer texture that rises beautifully.
Granulated Sugar: This sweet element balances the flavors; opt for fine sugar to ensure even mixing.
Unsweetened Cocoa Powder: For a hint of chocolatey depth; use high-quality cocoa for the best results.
Baking Powder and Baking Soda: These leavening agents help your cake rise to fluffy perfection.
Salt: Just a pinch enhances all the flavors in your cake; don’t skip it!
Eggs: Room temperature eggs emulsify the batter nicely and add moisture.
Whole Milk: Provides creaminess and helps bind everything together; feel free to substitute almond milk for a dairy-free version.
Creamy Peanut Butter: Use natural peanut butter for a richer flavor that isn’t overly sweet.
Vanilla Extract: A splash of vanilla adds warmth and depth to your cake’s flavor profile.

For the Frosting:

Butter: Softened at room temperature, it creates a smooth base for your frosting.
Powdered Sugar: Sifted to avoid lumps, it sweetens the frosting without being grainy.
Creamy Peanut Butter: Yes, more peanut butter! It makes the frosting irresistibly creamy and delicious.

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). Grease two round cake pans with butter or cooking spray and dust them with flour so that our beautiful cakes can slide right out.

Step 2: Mix Dry Ingredients

In a large bowl, whisk together all-purpose flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt. This step gets all those dry ingredients cozy before they meet their creamy partners.

Step 3: Combine Wet Ingredients

In another bowl, blend together eggs, whole milk, creamy peanut butter, and vanilla extract until smooth. You may want to use an electric mixer here unless you’re feeling very strong today!

Step 4: Merge Mixtures

Slowly pour the wet mixture into the dry ingredients while mixing until combined. Don’t overmix; we want fluffy cakes—not tough ones!

Step 5: Bake

Divide the batter evenly between the two prepared pans. Pop them in the oven and bake for about 25-30 minutes or until a toothpick comes out clean from the center.

Step 6: Cool & Frost

Let the cakes cool in their pans for about ten minutes before transferring them onto wire racks. Once cooled completely (patience is key!), whip up that dreamy peanut butter frosting by creaming together softened butter and powdered sugar along with more creamy peanut butter.

Now layer those cakes! Start with one layer on a plate or pedestal, spread frosting generously on top before adding the second layer. Frost around the sides too if you’re feeling fancy!

Transfer to plates and slice into generous pieces because who are we kidding? Nobody ever eats just one slice of this divine creation!
