Step 1: Prepare the Pan and Preheat

Preheat your oven to 350°F. Grease and flour a 10 x 15-inch cake pan. This size is perfect for even baking and creates the perfect cake-to-frosting ratio.

Step 2: Make the Cake Batter

In a large mixing bowl, add:

• 2 & 1/4 cups all-purpose flour

• 2 cups packed light brown sugar

• 1 cup peanut butter

• 1/2 cup butter (room temperature)

Use an electric mixer on low speed to blend these first four ingredients until the mixture is crumbly. This creaming step is key to a tender crumb.

Then add:

• 1 teaspoon baking powder

• 1/2 teaspoon baking soda

• 1 & 1/4 cups milk

• 2 teaspoons vanilla extract

• 3 eggs

Blend on low just until moistened, then beat on medium speed for 3 minutes to fully develop the structure of the batter.

Step 3: Bake the Cake

Pour the batter into your prepared pan and bake in the center of the oven for 35 to 40 minutes, or until a toothpick inserted in the center comes out clean.

Step 4: Prepare the Frosting

While the cake is baking, prepare your frosting:

• In a small microwave-safe bowl, combine 1/2 cup peanut butter and 2 tablespoons honey. Microwave briefly, just until soft and easy to stir.

• Stir in 1 teaspoon vanilla extract, 2 cups powdered sugar, and 4 to 5 tablespoons of milk, beating until smooth and spreadable.

Step 5: Frost While Hot

As soon as the cake is out of the oven, allow it to cool for 10 minutes—just enough to set slightly but still warm.

Spread the frosting evenly over the warm cake. The heat helps the frosting glide easily and slightly melt into the surface for extra flavor.

Top with 1 cup of mini chocolate chips, allowing them to gently soften over the warm frosting. They add a delightful bite and enhance the peanut butter flavor.
