My GF yellow sheet cake recipe has a fluffy texture without using butter-the oil and a good whisk do the trick! It's my secret to a soft, tender crumb that stays moist even after chilling.
Like all good yellow cake recipes, it has plenty of vanilla and extra egg yolks that make this cake tender and add to its signature yellow color.
The dairy free frosting is a chocolate Swiss buttercream. While it may seem intimidating, I think Swiss buttercream is actually more forgiving than traditional American buttercream, especially when working with dairy free butter. It is less sweet so the chocolate flavor shines through.
Ingredient Notes
- Gluten-Free Flour: For best results, use a 1:1 gluten-free flour blend that includes xanthan gum. Bob's Red Mill 1:1 and King Arthur Measure for Measure are both great options. If your blend doesn't include xanthan gum, add 1½ teaspoons per cup of flour.
- Eggs: You'll need 6 large eggs for the batter: 4 whole and 2 yolks plus egg whites for the frosting. Use room temp eggs for best results.
- Vegetable Oil: You can use any neutral oil, like avocado oil.
- Dairy-Free Butter: Use any quality plant-based butter. Don't use margarine or buttery spreads that are too soft.
- Dairy-Free Chocolate Chips: Use semi-sweet or bittersweet. Swap with chopped dark chocolate or baking chocolate.
- Cornstarch: You can substitute with arrowroot starch or tapioca starch but cornstarch is what I always use in gluten-free baking to mimic traditional cake flour.
- Non-Dairy Milk: You can use any unsweetened non-dairy milk, like almond or coconut milk.

Sift the Dry Ingredients
Combine the dry ingredients before mixing to prevent clumps, then whisk everything together until evenly distributed.

Mix the Cake Batter
Starting at a slow speed gives the eggs time to blend smoothly and prevents the dry ingredients from flying out of the bowl.

Increase the Speed
Once the ingredients are combined, increase the speed to medium to incorporate air into the batter, creating a lighter, fluffier cake with better structure.

Transfer the Batter
Tap the cake pan on the counter to level the batter and remove any air pockets. Rest for 10 to 15 minutes to allow the flour to rehydrate.

Bake
The cake is done when it looks golden on top and a toothpick inserted in the center comes out clean or with a few moist crumbs.

Frost
Once the cake has cooled, top with the dairy-free buttercream frosting and decorate as desired.
Recipe Tips
- Rotate the pan halfway through baking if your oven has hot spots.
- Let the cake cool completely in the pan before frosting. A warm cake will melt your frosting and create a mess.
- If the frosting looks too soft, chill it briefly, then beat again.
- Top the cake with sprinkles, fresh fruits, chopped nuts, chocolate chips, toasted coconut flakes, and so much more!

I fixed the recipe card. I rated this recipe as intermediate because of the additional steps to make the frosting. My taste testers agreed that it was worth the extra step.
