Ingredients
Method
- Preheat oven to 350°F (175°C) and line a 9×13 inch baking pan with parchment paper.
- Whisk melted butter and sugar until combined and slightly lightened.
- Add cocoa powder, salt, and baking powder and mix until thick and smooth.
- Stir in vanilla, then whisk in eggs one at a time until glossy.
- Fold in gluten-free flour just until combined.
- Add chocolate chips if using.
- Spread batter into pan and bake for 25–30 minutes until the top is shiny and a toothpick shows moist crumbs.
- Cool completely for at least 2 hours before slicing.
Notes
For best results, use a gluten-free flour blend containing xanthan gum, avoid overmixing, and allow the full cooling time for perfect fudgy slices.
