Gluten-Free Cake
- 3 cups gluten-free flour (360g, King Arthur’s Measure for Measure)
- 2 cups sugar (400g)
- 2 sticks butter (1 cup, 227g), softened
- 4 large eggs
- 2 large egg whites
- 3/4 cup whole milk
- 1/4 cup buttermilk
- 1/3 cup sour cream
- 1 tbsp + 2 tsp gluten-free baking powder
- 3 tsp vanilla extract
- 3/4 – 1 cup sprinkles
Buttercream Icing
- 1 cup unsalted butter (2 sticks), softened
- 1/3 cup heavy whipping cream
- 4.5 – 5 cups confectioners sugar, sifted
- 2 tsp clear vanilla extract
- Preheat the Oven: Preheat your oven to 350°F (175°C). Prepare two 8-inch or three 6-inch round cake pans by greasing them and lining the bottoms with parchment paper. Set aside.
- Sift the Dry Mix: In a bowl, sift together the gluten-free flour and baking powder. Set aside.
- Cream Butter & Sugar: In a large mixing bowl, cream the softened butter and sugar using a hand or stand mixer for 3-5 minutes until light and fluffy. Add the eggs and egg whites one at a time, beating well after each addition. Stir in the vanilla extract.
- Mix the Milk and Sour Cream: In a separate bowl, combine the whole milk, buttermilk, and sour cream.
- Prepare the Batter: Add the dry ingredients to the butter mixture in three parts, alternating with the wet ingredients, starting and ending with the dry ingredients. Mix until just combined, avoiding overmixing. Gently fold in the sprinkles until evenly distributed.
- Add Batter to Pans: Divide the batter evenly among the prepared pans. Smooth the tops with a spatula to ensure even layers. Fill 8-9 inch pans two-thirds to three-quarters full or 6-inch pans about halfway.
- Bake: Place pans in the oven and bake for 35-40 minutes, or until a toothpick inserted in the center comes out clean.
- Cool: Let cakes cool in pans for 10 minutes, then remove and transfer to wire racks to cool completely.
- Optional Freezing Step: Wrap cooled cakes in plastic wrap and freeze 6-24 hours for easier decorating. Before serving, thaw at room temperature for 2-4 hours. Avoid refrigeration to prevent drying.
- Assemble the Cake: Layer cooled cakes with your favorite frosting between layers. Frost the top and sides if desired.
- Sprinkle by Hand: Place the cake on a baking sheet or plate. Gently press sprinkles onto the sides, rotating the cake for even coverage.
- Make Buttercream Icing: Beat butter in a stand mixer with paddle attachment or hand mixer on medium until creamy. Add vanilla extract and mix well.
- Add Sugar and Cream: Gradually add sifted confectioners’ sugar, one cup at a time, mixing on low at first. Scrape bowl sides as needed.
- Adjust Consistency: Slowly add heavy cream. If too thick, add more cream one tablespoon at a time; if too thin, add more confectioners’ sugar until desired consistency is reached. For bright white icing, add a touch of purple food coloring.
Notes
- Use King Arthur’s Measure for Measure gluten-free flour for best results.
- Creaming butter and sugar until light and fluffy is key for texture.
- Be careful not to overmix batter to keep cake tender.
- Filling cake pans properly ensures even baking without overflow.
- Freezing cake layers before decorating helps make frosting easier and improves flavor.
- Do not refrigerate frosted cake to avoid drying it out; thaw frozen cake at room temperature before serving.
- Double the buttercream recipe if you want extra frosting for decoration.
- Adding a small amount of purple food coloring to buttercream neutralizes yellow tones for a bright white finish.
