This white chocolate peppermint cake is a three layered peppermint cake that has a white chocolate buttercream and is decorated with crushed candy canes. This is a perfect cake to serve this holiday season!
Preheat the oven to 350 degrees and line three 6-inch cake pans with parchment paper then nonstick spray. Set aside.
Peppermint Cake
In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
In a large bowl, whisk together the sugar, oil, eggs, egg whites, yogurt, vanilla extract, and peppermint extract until thoroughly combined. Alternately add the flour mixture and Lifeway milk, starting and ending with the flour (flour, milk, flour) and mixing just until combined.
Divide the batter amongst the three prepared cake pans and bake for 20-25 minutes, or until a toothpick inserted into the middle of the cakes come out clean. Let the cake cool in the pan for 25 minutes before removing and placing them on a wire rack to cool completely.
White Chocolate Buttercream
In a microwaveable-safe bowl, melt the white chocolate in 20 second intervals, stirring well after every 20 seconds until melted and smooth. Cool completely on the counter.
In the bowl of an electric stand mixer using the paddle attachment, beat together the butter on med-high speed until light and creamy (2-3 minutes). Add the powdered sugar, melted and cooled white chocolate, heavy whipping cream, and vanilla extract and mix on low speed until combined.
Increase the speed to high and beat the frosting until smooth and creamy (1-2 minutes).
Assemble
If needed, use a serrated knife to level off the tops of each cake layer to create a flat surface. Place one cake layer on a cake stand or plate and spread about ⅔ cup of frosting. Then sprinkle on some crushed candy canes. Repeat with the second layer. Top the cake with the last layer and spread on about ¼ cup of frosting.
Frost and smooth the outside of the cake with a thin crumb coat. Place the entire cake in the refrigerator or freezer for 10 minutes to chill.
Remove the cake from the refrigerator and finish frosting. Cover the sides and top of the cake again until frosted to your desire. Place the cake in the freezer for 10 more minutes. Then decorate with even more crushed candy cane pieces.
Keep any leftover cake slices in an airtight container in the refrigerator for up to 5 days.
Notes
Cake Pans: This recipe calls for three 6-inch cake pans. Line each pan with parchment paper and non-stick spray.
Measuring Flour: To help ensure you don’t add extra flour, follow these three simple steps: 1) Fluff up the flour using a fork. 2) Spoon the flour into your measuring cup. 3) Scrape a knife across the top of the measuring cup to level out the flour.
Room Temperature Ingredients: Any ingredient that needs to be at room temperature should be taken out of the refrigerator at least 1 hour before you want to bake. Do not skip this step! It's super important so that the ingredients can incorporate properly.
Dividing the Batter: To make sure I evenly divide up the batter amongst the cake pans I use a ½ measuring cup to scoop the batter into each pan. I count as I go and then switch to a tablespoon as I get less and less batter.
Crumb Coat: This is where we add a thin layer of frosting on the cake in order to catch the crumbs and keeps them secure. You’ll want to chill the cake in the refrigerator or freezer for 10 minutes after the crumb coat has been put on before the final frosting layer.
