Yield
One 6-inch two-layer cake
Gluten-Free Vanilla Rose Cake
½ cup plus 1 tablespoon sweet rice flour
½ cup white rice flour
½ cup plus 1 tablespoon tapioca flour
¼ cup brown rice flour
¾ teaspoon xanthan gum
1 teaspoon baking powder
½ teaspoon baking soda
½ teaspoon kosher salt
1 stick unsalted butter, room temperature, or ½ cup neutral oil
1 cup granulated sugar
4 large eggs
2 teaspoons pure vanilla extract
½ cup buttermilk, room temperature
8 ounces sour cream, room temperature
10 drops rose essence
Vanilla Rose Buttercream Frosting
3 sticks unsalted butter, room temperature
4½ cups powdered sugar, sifted
1 tablespoon pure vanilla extract
3 to 5 tablespoons heavy cream
½ teaspoon kosher salt
20 drops rose essence
Prepare the Cake Pans
Preheat the oven to 350°F.
Lightly grease two 6-inch cake pans with cooking spray or oil. Line the bottoms with parchment paper and lightly grease the parchment to ensure easy release after baking.
Make the Cake Batter
In the bowl of a stand mixer fitted with the paddle attachment, combine the sweet rice flour, white rice flour, tapioca flour, brown rice flour, xanthan gum, baking powder, baking soda, and kosher salt.
Add the butter or oil, granulated sugar, eggs, vanilla extract, buttermilk, sour cream, and rose essence directly to the dry ingredients.
Mix on low speed until the ingredients are combined. Increase the speed to medium and beat for 1 to 2 minutes until the batter becomes smooth and creamy. Scrape down the sides and bottom of the bowl as needed to ensure everything is evenly incorporated.
Fill the Pans
Divide the batter evenly between the prepared cake pans. Use an offset spatula to spread the batter into smooth, even layers.
Gently tap the pans on the counter a few times to release any trapped air bubbles.
Bake the Cake
Bake for 29 to 33 minutes or until the tops spring back when lightly touched and a toothpick inserted into the center comes out clean or with only a few moist crumbs attached.
Avoid opening the oven door during the first 25 minutes of baking, as this can cause the cake layers to sink.
Cool the Cake Layers
Remove the cakes from the oven and allow them to cool in the pans for 10 minutes.
Place a wire cooling rack over each pan and carefully invert to release the cakes. Remove the parchment paper and gently flip the layers right side up.
Allow the cakes to cool completely before frosting. Frosting warm cake layers will cause the buttercream to melt and slide.
Make the Vanilla Rose Buttercream
Place the softened butter in the bowl of a stand mixer fitted with the paddle attachment.
Beat on medium speed for 3 to 4 minutes until the butter becomes pale and fluffy.
Gradually add the powdered sugar in three additions, mixing well after each addition.
Add the vanilla extract, kosher salt, and rose essence.
With the mixer running on low speed, slowly add 3 tablespoons of heavy cream. Continue adding additional cream, 1 tablespoon at a time, until the frosting reaches a smooth, spreadable consistency.
Beat the frosting for another 2 to 3 minutes until light and fluffy.
Assemble the Cake
Place one cake layer on a serving plate or cake stand.
Spread approximately ½ cup of frosting evenly over the top.
Position the second cake layer on top and gently press it into place.
Apply a thin layer of frosting over the entire cake. This crumb coat helps trap loose crumbs and creates a smooth foundation for the final layer of frosting.
Chill the Cake
Place the cake in the refrigerator for 15 minutes to allow the crumb coat to set.
This step helps create a professional-looking finish and makes the final frosting layer easier to apply.
Finish and Decorate
Spread the remaining buttercream over the top and sides of the chilled cake.
Use an offset spatula or cake scraper to smooth the frosting.
Decorate with fresh edible roses, dried rose petals, edible flowers, or elegant buttercream piping if desired.
Refrigerate until ready to serve.
Rose essence can vary significantly in strength between brands. Start with the recommended amount and adjust to taste if needed.
For the most tender gluten-free texture, bring all refrigerated ingredients to room temperature before mixing.
If using oil instead of butter in the cake batter, choose a neutral-flavored oil such as avocado oil, vegetable oil, or canola oil.
Fresh edible flowers make this cake especially beautiful for bridal showers, baby showers, Mother’s Day celebrations, afternoon tea parties, and garden weddings.
Store the finished cake covered in the refrigerator for up to 4 days. Allow it to sit at room temperature for 20 to 30 minutes before serving for the best flavor and texture.
For a more pronounced floral flavor, add an additional 2 to 3 drops of rose essence to the frosting, tasting as you go to avoid overpowering the vanilla.
