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)

Directions

Step 1

Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking pan or line it with parchment paper.

Step 2

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.

Step 3

Add the eggs one at a time, whisking thoroughly after each addition. Stir in the vanilla extract.

Step 4

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.

Step 5

Pour the batter evenly into the prepared pan and smooth the top with a spatula.

Step 6

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.

Step 7

Let the brownies cool completely in the pan before adding the frosting.

Step 8

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.

Step 9

Spread the frosting evenly over the cooled brownies using an offset spatula or the back of a spoon.

Step 10

Slice into squares and serve. Store leftover brownies in an airtight container at room temperature for up to 3 days.
