Ingredients

Filling

  • 3 tbsp chocolate fudge sauce (thick consistency, see notes)

Cookie Dough

  • 1/2 cup butter (softened, salted or unsalted)
  • 3/4 cup brown sugar
  • 2 tbsp granulated sugar
  • 1 large egg
  • 2 tsp vanilla extract
  • 1 1/4 cup all-purpose flour
  • 1/2 cup dutch processed cocoa powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt

For Serving

  • Powdered sugar (for dusting)

Instructions

  1. Freeze the Filling: Place 6 dollops of chocolate fudge sauce (about 1/2 tablespoon each) onto a parchment-lined baking sheet or plate and freeze until solid. This step ensures the filling stays molten yet contained within the cookie during baking.
  2. Preheat the Oven: Set your oven to 350°F (177°C). Line a baking sheet with parchment paper and set it aside, ready for cookie placement.
  3. Cream Butter and Sugars: In a mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until the mixture is smooth and creamy, which helps incorporate air for a tender cookie texture.
  4. Combine Wet Ingredients: Beat in the large egg and vanilla extract until fully combined, ensuring an even consistency in the dough.
  5. Add Dry Ingredients: Sift together the flour, dutch processed cocoa powder, baking soda, and salt. Gradually add these dry ingredients to the wet mixture, stirring just until combined to avoid overmixing.
  6. Form Cookies with Filling: Divide the dough into 6 equal portions and roll into balls. Flatten each dough ball between your palms, place a frozen chocolate fudge dollop in the center, then fold the dough over to encase the filling fully. Place each cookie dough ball seam side down on the prepared baking sheet and gently pat the tops to about 1 to 1.5 inches thick.
  7. Bake: Bake in the preheated oven for 10-11 minutes. The edges should be set while the centers remain soft, allowing for the molten lava effect.
  8. Cool and Serve: Let the cookies cool on the baking sheet for 20 minutes to set the gooey center, then transfer to a cooling rack. Dust with powdered sugar before serving for a pretty finish and added sweetness. Enjoy warm for the best molten experience!

Notes

  • Use a thick, rich chocolate fudge sauce to ensure the molten center remains gooey and doesn't leak during baking.
  • Freezing the fudge dollops is crucial to prevent the filling from melting too quickly while baking.
  • You can use either salted or unsalted butter; if using salted butter, reduce added salt in the recipe accordingly.
  • Do not overbake to retain the molten lava center—10 to 11 minutes is ideal.
  • Serve cookies slightly warm for the best molten lava texture.
