These light and fluffy gluten-free vanilla cupcakes are the perfect treat for anyone avoiding gluten but craving something sweet and indulgent. The tender crumb and rich vanilla flavor make these cupcakes virtually indistinguishable from traditional versions, while the buttercream frosting adds that perfect crowning touch.
I developed this recipe after my niece was diagnosed with celiac disease, and these cupcakes quickly became her birthday tradition. The first time I served them at a family gathering, no one could tell they were gluten-free until I shared the secret!
Ingredients
- Unsalted butter: Room temperature ensures proper creaming with sugar for the fluffiest texture
- Granulated sugar: Provides sweetness and helps create that tender crumb structure
- Egg whites: Keeps cupcakes light colored and delicate
- Sour cream: Adds moisture and richness without making cupcakes dense
- Milk: Helps thin the batter to the perfect consistency
- Vanilla extract: Use pure extract for the best flavor profile
- Gluten free all purpose flour: King Arthur brand specifically produces superior results with its balanced blend
- Baking powder: Provides the perfect rise without the gluten structure
- Salt: Enhances all flavors and balances sweetness
Step-by-Step Instructions
- Prepare Your Equipment:
- Preheat your oven to 350°F and line a standard muffin tin with paper liners. Having everything ready before mixing ensures your batter won't sit too long before baking.
- Create the Base:
- Beat room temperature butter and sugar together for a full 1-2 minutes until the mixture becomes noticeably lighter in color and fluffy in texture. This crucial step incorporates air that helps create tender cupcakes.
- Add Wet Ingredients:
- Incorporate egg whites, sour cream, milk, and vanilla extract with a light touch of mixing. Overmixing at this stage can develop too much structure in the batter, resulting in tough cupcakes.
- Combine Dry Ingredients:
- Sift together the gluten free flour, baking powder, and salt in a separate bowl. This extra step eliminates lumps and aerates the dry ingredients for maximum fluffiness in the final product.
- Combine Carefully:
- Add the dry ingredients to wet ingredients gradually, mixing until just combined. The batter should look smooth but not overmixed as this can cause dense cupcakes.
- Bake to Perfection:
- Fill each liner half full with batter and bake for 17-19 minutes. The cupcakes are done when a toothpick inserted comes out with just a few moist crumbs attached rather than wet batter.
- Cool Completely:
- Allow cupcakes to cool fully before frosting. Even slightly warm cupcakes will cause frosting to melt and slide off the tops.

The secret weapon in these cupcakes is definitely the sour cream. I discovered this ingredient makes all the difference between a dry, crumbly gluten-free cupcake and one that stays moist for days. My mother, who swore she could always identify gluten-free baked goods, was completely fooled by these!
Working With Gluten Free Flour
Gluten free flour behaves differently than conventional wheat flour. The key is measuring precisely, preferably using a kitchen scale for accuracy. King Arthur Gluten Free All Purpose Flour contains xanthan gum, which helps mimic the structure that gluten would normally provide. If using a different brand, check the ingredients and add 1/4 teaspoon xanthan gum if your blend doesn't include it already.
Storage Tips
These cupcakes maintain their moisture surprisingly well compared to many gluten-free baked goods. Store unfrosted cupcakes at room temperature in an airtight container for up to 2 days. Once frosted, they should be refrigerated if keeping longer than a day. Let refrigerated cupcakes come to room temperature before serving for the best flavor and texture.

Frosting Variations
The recipe includes two classic frosting options, but you can get creative with flavors. Try adding citrus zest to the vanilla frosting for a bright twist. For chocolate lovers, the chocolate frosting can be enhanced with a tablespoon of espresso powder to deepen the flavor. A crowd favorite in my family is adding 1/4 cup of strawberry preserves to the vanilla frosting for a fruity variation that pairs beautifully with these vanilla cupcakes.
Serving Suggestions
These cupcakes make a beautiful presentation when topped with fresh berries or edible flowers. For a festive touch, coordinate sprinkle colors with your occasion. I often serve these alongside coffee for adults and milk for children. Consider creating a cupcake bar where guests can choose between vanilla and chocolate frosting, with various toppings available for customization.
Frequently Asked Questions
- → Can I use a different gluten-free flour blend?
Yes, you can substitute other gluten-free flour blends, but results may vary. King Arthur's Gluten Free All Purpose Flour is recommended because it contains xanthan gum and creates a consistent texture. If using another brand, ensure it contains xanthan gum or add 1/4 teaspoon to your dry ingredients.
- → Why does this recipe use only egg whites?
Using only egg whites helps create a lighter, fluffier texture and a more delicate crumb structure in the cupcakes. It also gives them a cleaner, whiter appearance that pairs beautifully with colored frostings.
- → How can I make the frosting more stable for warmer temperatures?
For a more stable frosting in warm weather, reduce the amount of heavy cream or milk, and consider chilling the frosting for 15-20 minutes before piping. You can also add 1-2 tablespoons of meringue powder to help stabilize the frosting without affecting the taste.
- → Can I make these cupcakes dairy-free?
Yes, you can make these dairy-free by substituting the butter with a plant-based butter alternative, using dairy-free yogurt instead of sour cream, and choosing a plant-based milk like almond or oat milk. For the frosting, use plant-based butter and a splash of dairy-free milk if needed for consistency.
- → How should I store leftover cupcakes?
Store frosted cupcakes in an airtight container at room temperature for 1-2 days, or in the refrigerator for up to 5 days. Let refrigerated cupcakes come to room temperature before serving for the best texture and flavor. Unfrosted cupcakes can be frozen for up to 3 months in a freezer-safe container.
- → Can I make mini cupcakes with this recipe?
Absolutely! For mini cupcakes, use a mini muffin pan with liners and reduce the baking time to approximately 10-12 minutes. This recipe should yield about 30-36 mini cupcakes. Check for doneness when a few moist crumbs remain on a toothpick inserted into the center.
