Ingredients
- 2 cups peach purée (reduced from fresh peaches)
- 1 box yellow or vanilla cake mix
- 1 package instant vanilla pudding mix
- 4 egg whites
- 1/2 cup sour cream
- 1/2 cup vegetable oil
- 1 tsp vanilla extract
- 1/2 tsp almond extract
- 1/4 tsp salt
- 1 cup heavy cream (for mousse)
- 1 cup peach purée (for mousse)
- 1 tbsp unflavored gelatin
- 1/4 cup granulated sugar
- 1 tbsp lemon juice
- 1 cup unsalted butter, softened
- 4 cups powdered sugar
- 2 tbsp heavy cream (for frosting)
- Assorted pastel food coloring
- Sprinkles for garnish
Instructions
- Reduce peach purée. Simmer fresh peach purée in a saucepan over medium-low heat for 15 minutes until thickened, then let cool.
- Prepare cake batter. Whisk cake mix, pudding mix, egg whites, one cup of peach purée, sour cream, oil, extracts, and salt until smooth.
- Bake cake layers. Divide batter into four six-inch pans and bake at 350°F for 23-25 minutes; cool completely on wire racks.
- Create mousse base. Whip cold heavy cream to stiff peaks; in a separate saucepan, cook remaining peach purée, gelatin, sugar, and salt until dissolved.
- Fold mousse mixture. Stir lemon juice and vanilla into the hot peach mixture, cool in an ice bath, then gently fold in the whipped cream.
- Whip creamy buttercream. Beat softened butter with salt until fluffy, then gradually add powdered sugar, vanilla, almond extract, and heavy cream until silky.
- Assemble cake layers. Layer cake rounds with the peach mousse filling, pressing down gently before chilling the stack to set.
- Seal with crumb coat. Spread a thin, even layer of buttercream over the entire cake and refrigerate for 30 minutes to lock in crumbs.
- Apply watercolor design. Dab patches of tinted buttercream onto the chilled cake and use a scraper to blend into a seamless watercolor finish.
- Add final decorations. Pipe dollops of buttercream around the top border and garnish with sprinkles before serving at room temperature.
Notes
- Ensure all peach purée is fully cooled before incorporating it into the cake batter or mousse to prevent melting the butter or deflating the cream.
- Keep your cake layers chilled throughout the assembly process to prevent the mousse from sliding and to maintain structural integrity.
- Use a warm, dry metal spatula when creating the watercolor effect to achieve a smooth, professional finish without dragging the frosting.
- If your buttercream appears lumpy or curdled, gently warm the mixing bowl over steam and re-whip until smooth and emulsified.
