What You’ll Need

For the bars:

1 cup 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 for frosting)
2 cups powdered sugar

Let’s Make It Together

Preheat your oven to 350°F (175°C). Grease a 10×15-inch jelly roll pan.
In a large bowl, cream together the softened unsalted butter, creamy peanut butter, granulated sugar, and brown sugar until the mixture is smooth and fluffy. This is where the magic begins!
Add the eggs one at a time, mixing well after each addition. Stir in the wonderful pure vanilla extract.
In another bowl, whisk together the flour, baking soda, and salt. Gradually mix the dry ingredients into the wet ingredients. Finally, stir in the quick oats, creating a wholesome and hearty batter.
Spread the batter evenly in the prepared pan and bake for 20-22 minutes or until golden and a toothpick inserted in the center comes out clean. Once baked, let cool completely in the pan.
For the dreamy frosting, beat together the creamy peanut butter and softened butter until you achieve a light and fluffy consistency. Add in the vanilla extract, then gradually mix in the powdered sugar and just enough milk to make the frosting spreadable.
Once your bars have cooled, frost them generously with the peanut butter frosting and cut them into squares. Serve and enjoy every cozy, delicious bite!

Fun Ways to Customize It

Chocolate Chip Delight: Add a cup of semi-sweet chocolate chips to the batter before baking for a rich, creamy chocolate addition.
Zesty Peanut Butter Swirl: Fold in some zesty lemon zest into the batter for a surprising twist that brightens the flavors beautifully.
Crunchy Peanut Topping: Sprinkle chopped peanuts over the frosting for a delightful crunch that complements the creamy texture.
Maple Brown Sugar Frosting: Give the frosting a cozy twist by using maple syrup instead of milk for a subtly sweet flavor.

Chef Emma’s Helpful Tips

Make-Ahead Friendly: These bars can be made ahead and stored for several days in an airtight container. They only get better as the flavors meld together!
Slicing Tip: For perfectly cut bars, use a sharp knife and run it under hot water, then dry it off before slicing through the layers.
Ingredient Swaps: If you don’t have creamy peanut butter, you can use crunchy for added texture, or swap it out for almond butter for a unique flavor.
Storage Suggestions: Store any leftover bars in an airtight container in the fridge. They’ll keep for about a week (if they last that long!).
