Description
Delicious, chewy peanut butter bars topped with creamy frosting, perfect for any occasion.
Ingredients
- 1 cup (2 sticks) unsalted butter, softened
- 1 cup creamy peanut butter
- 1 cup granulated sugar
- 1 cup packed light brown sugar
- 2 large eggs
- 1 teaspoon pure vanilla extract
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon salt
- 2 cups quick oats
- For the frosting:
- ½ cup creamy peanut butter
- 4 tablespoons unsalted butter, softened
- 2 teaspoons vanilla extract
- 2 cups powdered sugar
- 3–4 tablespoons milk (as needed)
Instructions
- Preheat your oven to 350°F (175°C) and grease a 10×15-inch jelly roll pan or line it with parchment paper.
- Cream together the softened butter, peanut butter, granulated sugar, and brown sugar until smooth and fluffy.
- Add the eggs gradually, mixing well after each addition, then stir in the vanilla.
- Whisk together the flour, baking soda, and salt in a separate bowl. Gradually add this mixture to the wet ingredients, stirring until just combined.
- Fold in the quick oats.
- Spread the batter evenly in the prepared pan and bake for 20–22 minutes, until the edges are golden brown and a toothpick inserted in the center comes out clean.
- Remove from the oven and let cool completely in the pan.
- For the frosting, cream together the ½ cup creamy peanut butter and 4 tablespoons softened unsalted butter until smooth, then mix in the 2 teaspoons vanilla extract. Gradually add the powdered sugar and enough milk to achieve your desired consistency.
- Once the bars have cooled, spread the frosting evenly on top, then slice into squares for serving.
Notes
Consider adding chocolate chips or nuts to the batter for extra texture. Store bars in an airtight container to maintain freshness.
