Description
This stunning peach watercolor cake features tender yellow layers infused with concentrated fruit purée and light, airy mousse. By blending pastel buttercream directly on the cake, you can achieve a professional hand-painted look using only basic kitchen tools.
Ingredients
- Yellow cake mix
- Fresh or frozen peaches
- Instant vanilla pudding mix
- Egg whites
- Sour cream
- Vegetable oil
- Vanilla extract
- Heavy cream
- Granulated sugar
- Salt
- Unflavored gelatin
- Fresh lemon juice
- Gel food coloring (pink, yellow, and red)
Instructions
- Reduce peach purée. Blend peaches in a food processor, simmer in a saucepan until thickened, and cool completely.
- Prepare cake batter. Combine cake mix, pudding, egg whites, sour cream, oil, extracts, and purée; whisk until smooth and divide into four greased 6-inch pans.
- Bake cake layers. Bake at 350°F for 23–25 minutes until a toothpick comes out clean; cool in pans for 5 minutes before transferring to a wire rack.
- Whip cream and prep gelatin. Whip heavy cream to stiff peaks; separately heat remaining purée with sugar, salt, and gelatin until bubbling.
- Fold in mousse. Cool gelatin mixture in an ice bath until thickened, then gently fold in the whipped cream.
- Assemble the layers. Layer cake rounds with peach mousse in between each, then chill for 15 minutes to set.
- Apply crumb coat. Frost the entire exterior with a thin layer of vanilla buttercream and chill for 30 minutes.
- Finish with watercolor. Dab patches of tinted buttercream onto the cake and use a scraper to lightly blend them into a watercolor design.
Notes
- Ensure the fruit reduction is completely cool before adding it to the batter to prevent melting the fats.
- Use a chilled bowl and high-speed mixer to achieve the firm, glossy peaks necessary for the mousse stability.
- Keep your scraper motion minimal during the final stage to avoid blending the colors into a single muddy tone.
- Pipe a ring of stiff buttercream around the edge of each layer to create a dam that prevents the mousse from leaking.
- If your frosting appears curdled due to temperature, briefly warm the bowl over steam to restore the emulsion.
