Ingredients
Scale
2 cups flour
2 cups sugar
1 ½ cups peanut butter
3 sticks butter
1 tsp baking soda
1 tsp vanilla extract
1 tsp salt
4 cups powdered sugar
2 eggs
½ cup milk
Instructions
Preheat the oven to 400°F (200°C). Grease a cookie sheet and set aside.
Mix dry ingredients: In a large bowl, combine flour, sugar, baking soda, and salt. Set aside.
Mix wet ingredients: In a separate bowl, whisk together eggs, milk, and vanilla extract. Set aside.
Combine peanut butter and butter: Melt the butter and peanut butter in a saucepan over low heat. Once melted, mix this with the dry ingredients and then add the egg mixture. Stir until well combined.
Bake the bars: Spread the batter evenly on the greased cookie sheet. Bake for 20 minutes, or until golden brown. Let cool completely.
Make the frosting: Melt butter and peanut butter, then mix in milk and powdered sugar to form a smooth frosting.
Frost the bars: Spread the peanut butter frosting evenly over the cooled bars.
Let the frosting set for a few minutes before slicing and serving. Enjoy!
Notes
For extra peanut butter flavor, you can sprinkle some chopped peanuts on top of the frosting.
Let the bars cool completely before frosting to ensure the frosting doesn’t melt into the bars.
Store any leftovers in an airtight container at room temperature.
