Instructions
Preparation Steps
Preheat oven to 350°F (175°C). Line a 9x9 inch baking dish with parchment paper, using binder clips to secure the edges. Lightly spray with nonstick cooking spray.
In a medium mixing bowl, combine the boxed brownie mix, melted butter, half and half, egg yolks, instant coffee, and vanilla extract. Stir just until incorporated; do not overmix. A few lumps are okay.
Fold in 1 cup of the chopped semi sweet chocolate.
Evenly spread the batter into the prepared baking dish. Bake for 35-40 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
Immediately sprinkle the remaining 1/4 cup of chopped chocolate over the hot brownies. Allow the brownies to cool completely. If desired, sprinkle with flaky sea salt.
Use the parchment paper to lift the brownies out of the dish. Cut into 16 squares. Store in an airtight container at room temperature for up to 3 days.
Notes
For an extra rich and fudgy texture, ensure your egg yolks are at room temperature. The instant coffee enhances the chocolate flavor without making the brownies taste like coffee.
