Equipment
- Wooden Spoon
- Frying Pan
- Whisk
- Baking Sheet
- Oven
Ingredients
- 2 1/4 cups cups All-purpose flour
- 1 1/2 cups cups Old fashioned oats
- 3/4 teaspoon teaspoon Baking powder
- 1/4 teaspoon teaspoon Baking soda
- 1/2 teaspoon teaspoon Fine sea salt
- 3/4 cup cups Unsalted butter
- 2 cups cups Packed light brown sugar
- 3/4 cup cups Creamy peanut butter
- 2 large Eggs
- 2 teaspoons teaspoons Vanilla extract
- 1 cup cups Semisweet chocolate chips
- 1 cup cups Peanut butter chips
- 2/3 cup cups Mini peanut butter cups
- 1/2 teaspoon teaspoon Flake sea salt
Instructions
- Preheat oven to 350 degrees F. Line a 13-by-9-inch baking pan with parchment paper.
- In a bowl, whisk together flour, oats, baking powder, baking soda, and salt; set aside.
- In a large bowl, combine melted butter, brown sugar, and peanut butter and stir until smooth. Whisk in eggs and vanilla. Fold in dry ingredients until just incorporated, then stir in chocolate and peanut butter chips and peanut butter cups, reserving a few tablespoons of each for the top (optional, but makes for extra pretty bars).
- Press dough into prepared pan. Scatter remaining chips and peanut butter cups on top, then sprinkle with sea salt.
- Bake for 25 to 28 minutes or until edges are lightly browned and center is just set. Do not overbake. Remove from oven and let cool to room temperature before lifting out of the pan and slicing into squares, rectangles, or triangles. Bars will keep, stored in an airtight container, for up to 5 days.
Notes
If you have leftovers, store them in an airtight container for up to five days. They also freeze wonderfully for longer storage!
