Description

These classic, rich bars combine a moist, peanut buttery base with a creamy peanut butter frosting—perfect for peanut butter lovers craving a nostalgic, sweet treat that’s easy to make and share.

Ingredients

Scale

  • 2 cups all-purpose flour

  • 2 cups granulated sugar

  • 1 teaspoon baking soda

  • 1 teaspoon salt

  • ½ cup whole milk

  • 1 teaspoon vanilla extract

  • 2 large eggs, beaten

  • 1 cup (2 sticks) unsalted butter

  • 1 cup creamy peanut butter

  • ½ cup (1 stick) unsalted butter

  • ½ cup creamy peanut butter

  • 2 tablespoons milk

  • 4 cups powdered sugar

Instructions

Step 1: Prepare Oven and Pan

Preheat your oven to 400°F (205°C). Grease a large sheet pan (approximately 13×18 inches) or line it with parchment paper for easy removal.

Step 2: Mix Dry Ingredients

In a large bowl, whisk together flour, granulated sugar, baking soda, and salt. Set aside.

Step 3: Mix Wet Ingredients

In a separate bowl, combine the milk, vanilla extract, and beaten eggs. Whisk lightly to blend.

Step 4: Melt Butter and Peanut Butter

In a medium saucepan over medium heat, melt the unsalted butter and creamy peanut butter together. Once the mixture reaches a gentle boil, immediately remove from heat.

Step 5: Combine Ingredients

Slowly stir the dry ingredients into the melted peanut butter mixture until combined. Then add the milk and egg mixture and stir until smooth and well incorporated.

Step 6: Bake the Bars

Pour and spread the batter evenly into your prepared pan. Bake for 20 minutes or until a toothpick inserted in the center comes out clean. Remove from the oven and allow the bars to cool completely in the pan.

Step 7: Make the Frosting

In a small saucepan, melt butter and peanut butter together over medium heat. Bring just to a boil, then remove from heat. Stir in milk, then gradually add powdered sugar, stirring continuously until the frosting is smooth and spreadable.

Step 8: Frost the Bars

Pour the warm frosting evenly over the cooled bars. Use a spatula to spread it smoothly. Let the frosting set at room temperature before slicing into squares.
