Ingredients

Scale

Cookies

  • 10 tablespoons (142 grams) unsalted butter, at cool room temperature
  • 3/4 cup (150 grams) granulated sugar
  • 1 large egg, at cool room temperature
  • 1 tablespoon light corn syrup
  • 1 teaspoon vanilla extract
  • 1 1/4 cups (159 grams) all-purpose flour
  • 6 tablespoons (32 grams) unsweetened natural cocoa powder
  • 1 teaspoon cornstarch
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon fine sea salt

Chocolate Drizzle

  • 1/2 cup (85 grams) milk chocolate chips
  • 1 teaspoon vegetable oil

Filling

  • 1 stick (113 grams) unsalted butter, at cool room temperature
  • 2 tablespoons (11 grams) unsweetened natural cocoa powder, sifted
  • 1 1/2 cups (188 grams) powdered sugar, sifted
  • 2 tablespoons warm water (about 100°F)
  • 1/2 teaspoon vanilla extract

Instructions

  1. Make the cookies: Preheat your oven to 350°F and line two baking sheets with parchment paper. In the bowl of a stand mixer fitted with the paddle attachment, beat the butter and sugar on medium-high speed until light and fluffy, about 2 to 3 minutes, scraping down the sides as needed. Add the egg, corn syrup, and vanilla extract, and mix until fully incorporated. In a separate bowl, whisk together the flour, cocoa powder, cornstarch, baking soda, and salt. With the mixer on low speed, gradually add the dry ingredients to the wet mixture and beat until combined. The dough will be soft and slightly sticky.
  2. Bake the cookies: Using a 1 ½-tablespoon spring-loaded scoop, drop balls of dough onto the prepared baking sheets. Bake for 8 to 9 minutes, or until the cookies are just puffed up and the edges are set. Remove the baking sheets to cooling racks and allow the cookies to cool for a few minutes on the sheet before transferring them to continue cooling. Note that the cookies will flatten as they cool.
  3. Prepare the chocolate drizzle: Place the milk chocolate chips and vegetable oil in a microwave-safe bowl. Microwave in 15-second intervals, stirring between each, until the chocolate is smooth and fully melted. Use a spoon or piping bag to drizzle the melted chocolate over the cooled cookies. Refrigerate the cookies until the chocolate is set, at least 30 minutes.
  4. Make the filling: In the clean bowl of the stand mixer with the paddle attachment, beat the butter on medium speed until smooth. Add the sifted cocoa powder and powdered sugar, beating until light and fluffy, about 3 minutes, scraping the bowl as needed. Add the warm water and vanilla extract, then beat on medium-high speed for about 2 minutes until very light and fluffy.
  5. Assemble the fudge rounds: Pipe or spread the filling onto the flat side of half the cookies. Gently press a second cookie on top of each to create sandwich rounds.
  6. Serve and store: Enjoy right away or store the assembled fudge rounds in an airtight container at room temperature for up to 1 day, in the refrigerator for up to 5 days, or freeze for up to 1 month. Note that colder fudge rounds may have a firmer texture and more pronounced chocolate flavor.

Notes

  • Ensure butter and egg are at cool room temperature to achieve the right cookie texture.
  • Parchment paper prevents sticking and promotes even baking.
  • Do not overbake cookies; they should be just set with puffed edges.
  • Chilled fudge rounds will be firmer and can be softened by bringing to room temperature before serving.
  • Light corn syrup adds moisture and chewiness to the cookies.
  • Microwave the chocolate chips in short bursts to avoid burning.
  • Sifting the cocoa powder and powdered sugar in the filling ensures a smooth, lump-free buttercream.
