Nutrition Information
Room Temperature Matters
Always bring your eggs and dairy-free alternatives to room temperature before mixing. Cold ingredients create lumps and uneven texture in gluten-free batters.
Don't Skip the Resting Step
Gluten-free flours like almond flour absorb moisture slowly. Let your batter rest for 5–10 minutes before baking for a significantly better crumb structure.
