In a small pot, melt together butter and dark chocolate. Stir consistently to avoid burning. Once they’re completely melted, take the pot off the heat.
Add the granulated sugar, brown sugar, cocoa powder, and whisk together until it’s combined. Add the egg one at a time, mixing after each addition.
Add the vanilla extract and instant coffee granules and mix until combined.
In a small bowl, mix together gluten-free flour blend and fine salt. Add the mixture to the pot and mix the batter until smooth.
Switch to a spatula or wooden spoon and mix in the chocolate chips. Set the pot aside to let the batter rest for 20 minutes.
While the batter rests, preheat the oven to 350°F (180°C). Grease and line an 8x8 inch square pan with parchment paper.
Pour the rested brownie batter into the prepared pan and bake for 30 minutes. Once the brownies come out of the oven, run a knife along the sides (between the brownies and parchment paper) to prevent them from sinking in the center.
Let the brownies cool completely before taking them out of the pan to cut and serve.
Notes
Dairy-Free: Simply swap out the butter for a vegan butter. Miyoko’s and Earth Balance are typically my top choices.Storage: Store the brownies in an airtight container for up to 3 days, or individually wrapped in a freezer bag in the freezer for up to 3 months.
