Ingredients
Cookie Base
- 2 sticks unsalted butter (1 cup), room temperature
- 1/2 cup sugar
- 1 cup brown sugar
- 2 large eggs
- 1 tsp vanilla extract
- 2 1/2 cups all-purpose flour
- 1 tsp salt
- 1 tsp baking soda
- 1/2 cup Butterfinger bars, chopped (about 3 big-sized bars)
Peanut Butter Frosting
- 3/4 cup peanut butter
- 1 stick unsalted butter (1/2 cup), room temperature
- 1 tsp vanilla extract
- 1 1/2 cups powdered sugar
- 3 tbsp milk
Topping
- 1 1/2 cups Butterfinger bars, chopped (about 5 big-sized bars)
Instructions
- Preheat the oven: Set your oven to 350°F (175°C) to warm up while you prepare the cookie base.
- Prepare the baking dish: Line a 9×13-inch baking dish with parchment paper, then spray it lightly with cooking spray. This will prevent sticking and make for easy removal of the bars.
- Make the cookie dough: In a large bowl, beat together 1 cup of room temperature butter, sugar, and brown sugar using a hand mixer until the mixture becomes light and creamy, about 3-4 minutes.
- Add eggs and vanilla: Incorporate the eggs one at a time, then add 1 tsp vanilla extract, continuing to beat until fully combined.
- Mix dry ingredients: Add the flour, salt, and baking soda to the wet ingredients. Beat with the hand mixer until just combined and a dough forms.
- Fold in Butterfinger bits: Gently mix in 1/2 cup of chopped Butterfinger candy bars until evenly distributed throughout the dough.
- Bake the cookie base: Spread the dough evenly into the prepared baking dish. Bake for 25 minutes or until the cookie layer is golden brown and a toothpick inserted comes out with few crumbs.
- Cool completely: Remove from oven and allow the cookie base to cool fully in the pan to room temperature.
- Prepare the frosting: In a clean large bowl, beat together 3/4 cup peanut butter and 1 stick (1/2 cup) room temperature butter until smooth and creamy without lumps.
- Add vanilla: Mix in 1 tsp vanilla extract until fully incorporated.
- Add powdered sugar and milk: Gradually beat in 1 1/2 cups powdered sugar and 3 tablespoons milk. Continue mixing until frosting is smooth and spreadable.
- Frost the bars: Evenly spread the peanut butter frosting over the cooled cookie base.
- Add topping and serve: Sprinkle the remaining 1 1/2 cups of chopped Butterfinger bars over the frosting. Slice into bars and serve.
Notes
- Ensure butter is at room temperature for easier creaming and smooth batter.
- Do not overmix the dough after adding flour to avoid tough cookies.
- Let the cookie base cool fully before frosting to prevent melting the frosting.
- You can substitute crunchy peanut butter for added texture in the frosting if desired.
- Store bars in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
