Recipe Information
Ingredients
- 1 cup Butter
- 1 cup Granulated sugar
- 1 cup Brown sugar (packed)
- 1 cup Peanut butter (creamy or chunky)
- 2 large Egg
- 2 teaspoons Vanilla extract
- 1 cup Rolled oats
- 1 cup All-purpose flour
- 0.33 cup Unsweetened cocoa powder
- 1 teaspoon Baking powder
- 0.5 teaspoon Salt
- 1.5 cups Powdered sugar
- 2 tablespoons Heavy cream or milk (for frosting)
- 0.33 cup Peanut butter (for frosting)
Instructions
Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking pan or line it with parchment paper.
In a large saucepan, melt the butter over medium heat. Remove from heat and stir in the granulated sugar, brown sugar, and peanut butter until smooth.
Add the eggs one at a time, whisking thoroughly after each addition. Stir in the vanilla extract.
In a medium bowl, combine the rolled oats, flour, cocoa powder, baking powder, and salt. Stir the dry ingredients into the peanut butter mixture until just combined.
Pour the batter evenly into the prepared pan and smooth the top with a spatula.
Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Avoid overbaking.
Let the brownies cool completely in the pan before adding the frosting.
While the brownies are cooling, prepare the frosting. In a medium bowl, beat the powdered sugar, peanut butter, and heavy cream (or milk) together until creamy and smooth.
Spread the frosting evenly over the cooled brownies using an offset spatula or the back of a spoon.
Slice into squares and serve. Store leftover brownies in an airtight container at room temperature for up to 3 days.
