Purple Velvet Mousse Cake – The Ultimate Royal Purple Dessert
👩🍳 Step-by-Step Instructions
Step 1: Prepare the Purple Velvet Sponge
Preheat your oven to 350°F (175°C).
Line an 8-inch square or round cake pan with parchment paper.
In a bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.
In a separate bowl, cream butter and sugar until light and fluffy (about 3–4 minutes).
Add eggs one at a time, mixing well after each addition.
Add vanilla extract.
Slowly add dry ingredients alternating with buttermilk.
Add your purple coloring until you reach a rich royal purple shade.
Pour batter into the pan and bake for 20–25 minutes.
Let it cool completely before adding mousse.
Pro Tip: For a moist texture, do not overbake. The center should spring back lightly when touched.
Step 2: Prepare the Purple Mousse Layer
Sprinkle gelatin over warm water and let it bloom for 5 minutes.
Heat gently until dissolved (do not boil).
In a large bowl, whip cold heavy cream until soft peaks form.
Add powdered sugar and vanilla extract.
Gently fold in the purple fruit puree.
Slowly pour in dissolved gelatin while mixing gently.
The mousse should be smooth, airy, and lightly sweet.
