Gluten-Free Chocolate Bourbon Cake
¼ cup oat flour
½ cup cornstarch
½ cup rice flour
1 cup glutinous rice flour
½ cup tapioca flour
2½ teaspoons baking powder
½ teaspoon baking soda
½ teaspoon xanthan gum
½ teaspoon kosher salt
⅔ cup unsweetened Black Dutch-process cocoa powder
1⅓ cups granulated sugar
2 sticks unsalted butter, softened and diced, or 1 cup neutral oil
4 large eggs
½ cup oil
1 cup bourbon
3 tablespoons pure vanilla extract
8 ounces sour cream
3 ounces instant chocolate pudding mix
½ package mini chocolate chips
Browned Buttercream Frosting
2 sticks unsalted butter
1 stick salted butter
4 cups powdered sugar
6 tablespoons heavy cream
1½ teaspoons bourbon
1 teaspoon pure vanilla extract
Prepare the Cake Pans
Preheat your oven to 350°F. Generously coat two 8-inch round cake pans with baking spray and line the bottoms with parchment paper if desired. Properly preparing the pans helps ensure the cake layers release easily after baking.
Mix the Dry Ingredients
In a large mixing bowl, whisk together the oat flour, cornstarch, rice flour, glutinous rice flour, tapioca flour, baking powder, baking soda, xanthan gum, kosher salt, cocoa powder, granulated sugar, and instant chocolate pudding mix. Whisk thoroughly to evenly distribute the ingredients and eliminate any lumps.
Combine the Wet Ingredients
In a separate large bowl, whisk together the softened butter, eggs, oil, bourbon, vanilla extract, and sour cream until smooth and creamy. The sour cream helps create a tender crumb while adding richness and moisture to the cake.
Make the Cake Batter
Gradually add the wet ingredients to the dry ingredients, mixing until everything is combined and no dry streaks remain. Fold in the mini chocolate chips until evenly distributed throughout the batter.
The batter should be thick, smooth, and glossy. Avoid overmixing, which can affect the final texture of the cake.
Bake the Cake Layers
Divide the batter evenly between the prepared cake pans. Smooth the tops with a spatula.
Place the pans in the preheated oven and bake for 22 to 25 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs attached.
Remove the cakes from the oven and allow them to cool in the pans for 10 minutes. Carefully turn the layers out onto wire racks and let them cool completely before frosting. This typically takes 45 minutes to 1 hour.
Brown the Butter
While the cake layers cool, prepare the frosting.
Place the unsalted butter and salted butter in a medium saucepan over medium heat. Allow the butter to melt completely, stirring occasionally.
Continue cooking until the butter develops a deep golden-brown color and releases a rich, nutty aroma. Brown bits will form at the bottom of the pan. These toasted milk solids contain tremendous flavor and should be included in the frosting.
Immediately transfer the browned butter to a heatproof bowl.
Allow it to cool for about 15 minutes, then refrigerate until it becomes cool and nearly solid, stirring every 15 minutes to maintain a smooth consistency. This process takes approximately 1 hour.
Prepare the Browned Buttercream Frosting
Transfer the chilled browned butter to the bowl of a stand mixer fitted with the paddle attachment.
Beat on medium speed for about 3 minutes until fluffy and lightened in color.
Gradually add the powdered sugar while mixing on low speed. Continue mixing until fully incorporated.
In a small bowl, whisk together the heavy cream, bourbon, and vanilla extract.
Slowly add the cream mixture to the frosting while mixing. Increase the speed to medium and beat until the frosting becomes smooth, creamy, and fluffy.
Scrape down the sides of the bowl as necessary to ensure an even texture.
Assemble the Cake
Reserve approximately ⅓ cup of frosting and transfer it to a piping bag fitted with a decorative star tip.
Place one cake layer on a serving plate or cake stand. Spread an even layer of browned buttercream across the top.
Add the second cake layer and frost the top and sides of the cake with the remaining frosting. Smooth the frosting using an offset spatula or create decorative swirls as desired.
Pipe decorative borders or rosettes around the top edge of the cake using the reserved frosting.
Allow the finished cake to rest at room temperature for 20 minutes before slicing and serving.
For an even richer chocolate flavor, use high-quality Dutch-process cocoa powder.
The bourbon enhances the chocolate and browned butter flavors while adding depth and warmth to the cake.
Mini chocolate chips provide delightful pockets of melted chocolate throughout every slice.
Store the cake covered at room temperature for up to 2 days or refrigerate for up to 5 days.
For the best flavor and texture, bring refrigerated cake to room temperature before serving.
This moist gluten-free chocolate bourbon cake is perfect for birthdays, holiday gatherings, dinner parties, and special celebrations. The combination of rich chocolate cake, smooth bourbon notes, and nutty browned buttercream creates an unforgettable dessert that tastes every bit as indulgent as a traditional bakery cake.
