1/2 cup sugar
1 cup brown sugar
2 eggs
1 tsp vanilla extract
2 1/2 cups flour
1 tsp salt
1 tsp baking soda
1/2 cup Butterfinger bars, chopped (3 big sized bars)
Peanut Butter Frosting
3/4 cup peanut butter
1 stick unsalted butter, room temperature
1 tsp vanilla extract
1 1/2 cups powdered sugar
3 tbsp milk
Topping
1 1/2 cups Butterfinger bars, chopped (5 big sized bars)
Instructions
Preheat Oven: Preheat your oven to 350°F (175°C) to get it ready for baking the cookie bars.
Prepare Pan: Line a 9x13 inch baking dish with parchment paper and spray it lightly with cooking spray to prevent sticking. Set aside.
Mix Cookie Base: In a large bowl, beat 1 cup of room temperature butter, 1/2 cup sugar, and 1 cup brown sugar using a hand mixer until the mixture is light and creamy. Add 2 eggs and 1 tsp vanilla extract, then beat until fully combined.
Add Dry Ingredients: Add 2 1/2 cups flour, 1 tsp salt, and 1 tsp baking soda to the wet ingredients. Beat using the hand mixer until just combined. Gently fold in 1/2 cup chopped Butterfinger bars.
Bake Cookie Layer: Scoop the cookie dough into the prepared baking dish and spread it evenly. Bake in the preheated oven for 25 minutes or until the top is golden brown.
Cool Cookie Layer: Remove the baking dish from the oven and allow the cookie base to cool completely before adding frosting.
Make Frosting: In another large bowl, beat 3/4 cup peanut butter and 1 stick of room temperature butter until smooth and creamy. Add 1 tsp vanilla extract and mix well. Gradually beat in 1 1/2 cups powdered sugar and 3 tbsp milk until the frosting is smooth and spreadable.
Frost Cookie Bars: Spread the peanut butter frosting evenly over the cooled cookie base.
Add Topping: Sprinkle 1 1/2 cups chopped Butterfinger bars evenly over the frosting layer.
Serve: Slice into bars and serve. Enjoy your Butterfinger Cookie Bars!
Notes
Make sure the cookie base is completely cooled before frosting to prevent melting.
Use room temperature butter for easier mixing and better texture.
For a thicker frosting, reduce the milk slightly or add more powdered sugar.
Sprinkle extra chopped Butterfinger bars on top for added crunch and flavor.
Store bars in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
