Gather These Simple Ingredients

For the Bars:

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
3–4 tablespoons milk (as needed)
2 cups powdered sugar

Let’s Make It Together

Preheat Oven & Prepare Pan: Heat your oven to 350°F (175°C). Grease a 10×15-inch jelly roll pan or line it with parchment paper for easy removal.
Mix the Base: In a large bowl, cream together the softened butter, peanut butter, granulated sugar, and brown sugar until smooth and fluffy. Add in the eggs one at a time, mixing well after each addition. Then, stir in the vanilla extract.
Combine Dry Ingredients: In another bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add the dry mixture to the wet ingredients, mixing until just combined. Finally, fold in the quick oats until evenly distributed.
Bake: Spread the batter evenly in the prepared pan. Bake for 20–22 minutes, until the edges are golden brown and a toothpick inserted in the center comes out clean. Be careful not to overbake!
Cool: Once baked, remove the pan from the oven and let the bars cool completely in the pan. This helps to achieve the perfect texture.
Make the Frosting: In a medium bowl, beat together the creamy peanut butter and softened butter until smooth. Mix in the vanilla extract. Gradually add the powdered sugar, alternating with milk, until the frosting is light and spreadable.
Frost & Cut: Spread the frosting evenly over the cooled bars. Once frosted, cut into squares or rectangles for serving.

Delicious Variations to Try

Chocolate Drizzle: Top the frosted bars with a drizzle of melted chocolate for a rich and indulgent twist.
Add Nuts: Mix in some chopped peanuts or walnuts for a crunchy contrast to the creamy texture.
Dried Fruit: Incorporate raisins or dried cranberries for a burst of sweetness and chewy texture.
Cocoa Powder: Add a few tablespoons of cocoa powder to the batter for a chocolatey version of these classic bars.
