Gluten-Free Sheet Pan Pancakes, Crispy Broiled

Large-batch pancakes baked on a sheet pan and finished under the broiler for a golden top. Made with brown rice flour, potato starch, and tapioca starch for structure and tenderness. Warm buttermilk and milk create a tender crumb. Bake until springy, brush with melted butter, then broil briefly until lightly browned. Serves a crowd.

Tips
For even baking, spread batter carefully to corners before baking.
Watch broiler closely; 1-2 minutes goes quickly and top burns easily.
Xanthan gum binds the starch blend; do not omit or batter will be grainy.
Good to Know
Airtight container at room temperature up to 2 days, or refrigerate up to 4 days.
Prepare dry ingredients in bowl the night before. Combine wet and dry just before baking.
Top with maple syrup, fresh fruit, whipped cream, or nut butter.
Common Mistakes
Do not skip the broiler step to avoid a pale, dense top; broiling adds texture and color.
Do not open oven during initial 12-15 minute bake to avoid uneven rise.
Do not skip xanthan gum to avoid grainy, crumbly texture from the starch blend.
