Buckeye Brownie Cookies Recipe

Author: Mandy
These Buckeye Brownie Cookies bring together the best parts of a brownie, a cookie, and a buckeye candy in one rich, chocolatey treat. The cookie is made with a boxed brownie mix and topped with creamy peanut butter frosting and a smooth ganache topping. They’re easy to make but taste bakery-worthy, and they’re always a hit with chocolate peanut butter fans.

Ingredients
  

Cookies

  • 1 (18-ounce) box fudge brownie mix
  • 2 tablespoons all-purpose flour
  • 1/4 cup canola or vegetable oil
  • 2 large eggs

Frosting

  • 1 cup creamy no-stir peanut butter like Jif or Skippy
  • 1/2 cup unsalted butter room temperature
  • 2 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • 2-4 tablespoons milk

Ganache

  • 1 cup semi-sweet chocolate chips
  • 1/3 cup heavy cream

Instructions
 

  • Preheat the oven to 350 degrees F and line two baking sheets with parchment paper.
  • Mix the brownie mix, flour, oil, and eggs in a large bowl until a thick dough forms.
  • Scoop 2 tablespoon-sized balls of dough and place them on the baking sheets, spacing them 2 inches apart.
  • Bake for 10–12 minutes until the edges are set. Let cool completely.
  • In a large bowl, beat together peanut butter and butter until smooth. Add powdered sugar, vanilla, and salt; beat until fluffy. Add milk as needed until spreadable.
  • Spread a generous layer of frosting on each cookie. Refrigerate while preparing ganache.
  • Place chocolate chips in a microwave-safe bowl. Pour heavy cream over the chips and microwave for 40 seconds. Let sit 1 minute, then whisk until smooth.
  • Spoon or drizzle ganache over the frosted cookies. Let set at room temperature or refrigerate until firm.

Notes

  • Store the cookies in an airtight container at room temperature for 2-3 days or in the refrigerator for up to 5 days.
  • Freeze the cookies in a single layer on a baking sheet until firm, then transfer them to an airtight container or freezer bag. They’ll keep for up to 3 months. Thaw in the fridge or at room temperature before eating.
