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.
Storage Instructions for Gluten-Free Apple Crisp
Store covered at room temperature for 1 day, then refrigerate for up to 4 days. Reheat at 350°F for 10 minutes to re-crisp the topping.
Gluten-Free Apple Crisp Troubleshooting
Why is my crisp topping sandy and loose?
The butter was cut too fine or was too warm, so it didn't create the clumps that bake into crunchy clusters.
Cut the butter into pea-sized pieces and rub them in only until some pieces remain visible. Chill the topping for 10 minutes before baking if your kitchen is warm.
Why is the filling watery?
The apples released more juice than the cornstarch could bind, or the cornstarch didn't reach a boil.
Increase cornstarch to 3 tablespoons and make sure the filling is visibly bubbling for at least 5 minutes before removing from the oven.
