⅓ cup granulated sugar

½ cup smooth peanut butter

1 teaspoon vanilla extract

1 large egg, room temperature

1¼ cups all-purpose flour

46 tablespoons thick caramel sauce

Instructions

  1. Preheat oven to 350°F (175°C) and line two baking sheets with parchment paper.

  2. Cream butter, brown sugar, and granulated sugar until smooth and fluffy.

  3. Add peanut butter and vanilla extract; beat until combined.

  4. Mix in the egg until incorporated.

  5. In another bowl, whisk together flour, baking soda, and salt. Gradually add to wet ingredients.

  7. Scoop 3-tablespoon portions onto prepared baking sheets.

  8. Bake for 10–12 minutes until edges are golden and centers slightly underbaked.

  9. Cool on the baking sheet for 10 minutes, then transfer to a wire rack.

For the Caramel Buttercream:
10. Beat butter until creamy.
11. Gradually add powdered sugar, beating after each addition.
12. Add caramel sauce and vanilla extract; beat until smooth, adjusting consistency as needed.
13. Once cookies are cool, frost with caramel buttercream and sprinkle with remaining Snickers pieces.
14. Chill to set frosting before serving.

Notes

For extra crunch, add crushed peanuts to the dough.

Freeze Snickers bars slightly before chopping for easier handling.

Make smaller cookies by using a smaller scoop and adjusting bake time.

Cookies taste best when brought to room temperature after chilling.

Store frosting separately if baking ahead and frost before serving.
