How to Make GF Brownies (Step by Step)
Step 1: Melt Butter + Chocolate
Melt together over low heat, stirring constantly. Do NOT let it boil or the chocolate will seize. Remove from heat as soon as it is smooth and glossy.
Step 2: Add Sugar and Beat
Stir in the sugar while the mixture is still warm. The residual heat helps dissolve the sugar crystals, which creates the crackly top.
Step 3: Add Eggs Vigorously
This is the step most people skip. Add eggs one at a time and beat hard — 30 seconds of vigorous stirring per egg. This aerates the batter slightly and creates the signature shiny, crackle-top layer.
Step 4: Fold in Dry Ingredients
Sprinkle flour, cocoa, and salt on top. Fold gently — 15-20 strokes maximum. Overmixing = tough, cakey brownies instead of fudgy ones.
Step 5: Bake
350°F for 22-28 minutes. Pull them when the top looks set but a toothpick comes out with moist crumbs (not wet batter). They firm up significantly as they cool.
Step 6: Cool Completely
The hardest step. GF brownies are basically chocolate pudding when hot. They need at least 1 hour of cooling to set into the fudgy texture you want. For even fudgier brownies, refrigerate for 2 hours before cutting.

Expert Tips
The Secret: Cold Brownies Are Better
Seriously. Refrigerate the cooled brownies for 2+ hours before cutting. They become incredibly dense and fudgy — like a GF version of a chocolate truffle bar.
Don't Overbake
Set a timer for 22 minutes and check. GF brownies go from fudgy to dry in a 2-minute window. When in doubt, pull them out earlier.
Use 🛒parchment paperAmazon ↗
Lining the pan with parchment makes removal easy and prevents sticking. Leave overhang on two sides so you can lift the whole slab out.

FAQs
Why are my brownies cakey instead of fudgy?
You either overbaked or overmixed. Use a timer and fold the flour in gently with just 15-20 strokes.
Do I need to add 🛒xanthan gumAmazon ↗?
No! The melted chocolate provides all the structure needed. Adding xanthan gum would make them gummy.
Can I double this recipe?
Yes — use a 9x13 pan and bake for 28-35 minutes.

Ingredients
- 1/2 cup (112g) unsalted butter
- 8 oz semi-sweet chocolate, chopped (or chocolate chips)
- 1 cup (200g) granulated sugar
- 2 large eggs, room temperature
- 1 tsp pure vanilla extract
- 1/2 cup (70g) gluten-free 1-to-1 baking flour
- 1/4 cup (25g) unsweetened cocoa powder
- 1/4 tsp salt
- Optional: 1/2 cup chopped walnuts or extra chocolate chips
Instructions
Preheat oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper, leaving overhang on two sides.
Melt butter and chopped chocolate together in a medium saucepan over low heat, stirring constantly until smooth. Remove from heat.
Stir in the sugar until fully combined. The mixture will be thick and glossy.
Add the eggs one at a time, beating vigorously with a wooden spoon or spatula after each addition. Add vanilla.
Sprinkle the GF flour, cocoa powder, and salt over the chocolate mixture. Fold gently until just combined — do not overmix.
Fold in walnuts or extra chocolate chips if desired.
Pour into the prepared pan and smooth the top.
Bake for 22-28 minutes. The top should be set and crackly, but a toothpick inserted should come out with moist crumbs (not wet batter).
Cool completely in the pan before lifting out using the parchment overhang. Cut into 16 squares.

Celiac Safety Glossary
- Celiac disease
- Celiac disease is a serious autoimmune disorder in which ingesting gluten — a protein found in wheat, barley, and rye — triggers an immune response that damages the small intestine's villi, affecting approximately 1 in 100 people worldwide according to the Celiac Disease Foundation.
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
- Malt (Barley)
- Malt is fermented barley used as a flavoring or sweetener in cereals, chocolates, and beer; it is a major source of hidden gluten that is often overlooked on ingredient lists.
