Stand Mixer

Ingredients

Bars

2 cups all-purpose flour
1 1/2 cups quick rolled oats
1 cup sugar
1 cup light brown sugar
2/3 cup peanut butter
1 cup butter
2 eggs
1 tsp vanilla extract
1 tsp baking soda
1/2 tsp salt

Topping

1/2 cup peanut butter
2 cups confectioners' sugar
6 Tbsp whole milk
1 1/2 cups Reese's peanut butter cups chopped

Instructions

Preheat the oven to 350 degrees Fahrenheit (177 degrees Celsius). Lightly butter or spray a full-size cookie sheet (with sides) with Pam (or any cooking spray you prefer).
In a medium-sized mixing bowl, whisk together the oats, flour, baking soda, and salt. Set aside.
In the bowl of a stand mixer, beat together the peanut butter, butter, and sugars for 30 seconds. Turn the speed to low and add one egg at a time. Add the vanilla and mix until combined.
Remove the bowl from the stand mixer. Fold in the dry ingredients. Do not overmix. Pour into the prepared pan and pat down until even.
Place in the oven and bake for 15–20 minutes, or until the top begins to brown.
Meanwhile, prepare the topping by beating the powdered sugar, peanut butter, and milk in a small bowl. Chop the peanut butter cups.
Remove the bars from the oven and place the pan on a wire rack. Immediately spread the topping over the warm bars (it will become melty and shiny). Sprinkle the chopped peanut butter cups over the top of the peanut butter layer. Allow to cool completely before cutting into Reese's bars.

Notes

STORE Chocolate Peanut Butter Bars in an airtight container at room temperature for up to 4 days. If your kitchen runs warm or you want them to last a bit longer, you can refrigerate them for up to 7 days.

To FREEZE, layer the bars between sheets of parchment paper in a freezer-safe container. They’ll keep well frozen for up to 2 months. Thaw in the refrigerator or at room temperature. If you prefer them slightly warm, microwave individual slices for 10–15 seconds.
