Light and Fluffy Gluten Free Sponge Cake
This gluten free sponge cake is so light and tender that nobody will guess it’s made without wheat flour. It rises into a golden, delicate crumb that holds up beautifully to fresh fruit and whipped cream.
Whether you’re baking for a birthday or just want a simple afternoon cake, this one comes together quickly and bakes into a reliably fluffy sponge every time.
Why This Gluten Free Sponge Cake Works
Beating the eggs and sugar until thick and pale gives the cake its lift; no separate egg white folding is needed. A small amount of melted butter keeps the crumb moist for days, so it doesn’t dry out the way some gluten free bakes can.
The blend of gluten free flour and cornstarch mimics the lightness of cake flour, and the batter comes together in about 15 minutes. It’s my go-to for shortcake, trifles, or just snacking with a dusting of powdered sugar.
Ingredients
- 4 large eggs, at room temperature: cold eggs won’t whip up as fluffy, so let them sit out for 30 minutes first
- ¾ cup granulated sugar
- 1 tbsp vanilla extract
- 1 cup gluten free all-purpose flour blend (with xanthan gum): I use one that already contains xanthan gum
- ¼ cup cornstarch
- 1½ tsp baking powder
- ¼ tsp salt
- ¼ cup unsalted butter, melted and cooled slightly: for a dairy-free version, see Variations
Variations and Substitutions
- Dairy free: swap the melted butter for an equal amount of melted coconut oil or a neutral vegetable oil. The cake will still be tender, though the buttery flavor will be missing.
- Citrus twist: add 1 tbsp finely grated lemon or orange zest to the eggs and sugar before beating.
- Almond extract: replace the vanilla with ½ tsp almond extract for a slightly nutty, holiday vibe.
- For a chocolate version, try our Gluten Free Chocolate Sponge Cake.
How to Make Gluten Free Sponge Cake
Step 1: Beat the Eggs and Sugar
Preheat your oven to 350°F (180°C). Grease an 8-inch round cake pan and line the bottom with parchment paper. In a large bowl, beat the 4 eggs, ¾ cup sugar, and 1 tbsp vanilla with an electric mixer on high speed until the mixture is very thick, pale, and forms a ribbon when you lift the beaters. This takes about 5 minutes.
You’ll see the volume triple and the color turn almost white. That’s the structure behind the cake’s lift, so don’t rush this step.
Step 2: Fold in the Dry Ingredients
In a separate bowl, whisk together the 1 cup gluten free flour, ¼ cup cornstarch, 1½ tsp baking powder, and ¼ tsp salt. Sift the mixture over the egg foam in three additions, gently folding with a rubber spatula after each one until no white streaks remain.
Drizzle the ¼ cup melted butter down the side of the bowl and fold it in with a few broad strokes. Stop as soon as the batter looks uniform; overmixing will knock out the air and leave you with a dense cake.
Step 3: Pour and Bake
Scrape the batter into the prepared pan and smooth the top. Bake for 25 to 30 minutes, until the cake is golden and the center springs back when lightly pressed.
A toothpick inserted in the middle should come out clean. The cake will pull away slightly from the sides of the pan, which is a good sign it’s done.
Step 4: Cool and Slice
Let the cake cool in the pan for 10 minutes, then run a knife around the edge and turn it out onto a wire rack to cool completely.
Once it’s no longer warm, slice and serve with a dusting of powdered sugar, fresh berries, or a dollop of softly whipped cream. The crumb will be airy and tender right down to the last bite.
Tips for a Light, Airy Sponge
- Room temperature eggs are nonnegotiable. If you forgot to pull them out, place them in a bowl of warm water for 5 minutes.
- Fold the flour in gently and stop the moment it’s incorporated. A few small lumps of flour are better than a batter that has lost its air.
- Do not open the oven door during the first 20 minutes of baking. The rush of cool air can cause the center to sink.
- Use a light-colored metal pan if you have one; dark pans can overbrown the crust before the middle sets.
Bake times by pan size:
| Pan Size | Bake Time |
|---|---|
| 8-inch round | 25–30 minutes |
| 9-inch round | 22–27 minutes |
| 12-cup muffin tin | 18–22 minutes |
Keeping Sponge Cake Fresh
- Refrigerate: store covered at room temperature for up to 2 days, or in the refrigerator for up to 4 days in an airtight container.
- Reheating: a 10-second zap in the microwave revives the soft texture of refrigerated slices.
- Serve cold: the cake tastes great straight from the fridge, especially with a drizzle of honey.
What to Serve with Gluten Free Sponge Cake
Spoon a generous pile of macerated strawberries over each slice, their juices soak into the crumb without making it soggy. A cloud of lightly sweetened whipped cream balances the cake’s delicate sweetness, and a tart lemon curd on the side cuts through the richness for something more lively.
Frequently Asked Questions
Can I use a different gluten free flour blend?
Yes, any 1:1 all-purpose gluten free blend with xanthan gum will work. If yours doesn’t contain xanthan, add ¼ tsp to the dry ingredients.
Why did my cake sink in the middle?
It’s usually one of two things: the cake was underbaked, or the oven door was opened too soon. Let it bake until the center feels springy and a toothpick comes out clean.
Can I double this recipe?
Yes, double all ingredients and divide the batter between two greased 8-inch pans. The bake time will remain about the same; start checking at 23 minutes.
How do I know when the cake is done?
Press the center gently. It should spring back without leaving a dent. A toothpick inserted in the middle should come out with just a few moist crumbs, not wet batter.
