  • 2 teaspoons gelatin powder

1. Preparing the Cake:

  • Preheat your oven to 350°F (175°C). Grease and flour a round cake pan.
  • In a medium bowl, whisk together the flour, baking powder, and salt.
  • In a separate bowl, cream together the softened butter and granulated sugar until light and fluffy.
  • Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
  • Gradually add the dry ingredients to the wet ingredients, alternating with the milk.
  • Add a few drops of purple food coloring and mix until the desired shade is achieved.
  • Pour the batter into the prepared cake pan and bake for about 25-30 minutes, or until a toothpick inserted into the center comes out clean.
  • Allow the cake to cool completely before removing it from the pan.

2. Making the Purple Mousse:

  • In a mixing bowl, whip the chilled heavy cream until soft peaks form.
  • Gradually add the powdered sugar and vanilla extract, continuing to whip until stiff peaks form.
  • In a separate bowl, sprinkle the gelatin powder over the cold water and let it bloom for a few minutes.
  • Microwave the bloomed gelatin for a few seconds until it dissolves completely.
  • Gradually fold the gelatin mixture into the whipped cream.
  • Add purple food coloring and gently fold until the color is evenly distributed.
  • Set aside a small portion of the mousse for decorating and refrigerate the remaining mousse until ready to use.

3. Assembling the Cake:

  • Place the cooled cake on a serving plate.
  • Spread a layer of the purple mousse evenly over the cake.
  • Repeat with additional layers of cake and mousse until all the cake and mousse are used, ending with a layer of mousse on top.
  • Smooth the top using an offset spatula and refrigerate the cake for at least 4 hours or overnight to set.

4. Preparing the Purple Mirror Glaze:

  • In a small saucepan, combine the granulated sugar and water. Bring to a simmer over medium heat until the sugar dissolves.
  • Stir in the sweetened condensed milk and remove from heat.
  • In a separate bowl, sprinkle the gelatin powder over the cold water

 and let it bloom.

  • Microwave the bloomed gelatin for a few seconds until it dissolves completely.
  • Gradually add the gelatin mixture to the condensed milk mixture, stirring until well combined.
  • Add purple food coloring and mix until the desired color is achieved.
  • Allow the glaze to cool slightly.

5. Glazing the Cake:

  • Remove the chilled cake from the refrigerator and place it on a wire rack set over a baking sheet to catch any drips.
  • Slowly pour the purple mirror glaze over the chilled cake, ensuring that it covers the top and sides evenly.
  • Use an offset spatula to smooth out any excess glaze and create a mirror-like finish.
  • Allow the glaze to set for a few minutes.

6. Decorating and Serving:

  • Take the reserved portion of the purple mousse and transfer it to a piping bag fitted with a decorative tip.
  • Pipe decorative patterns or rosettes around the edges of the cake.
  • Refrigerate the cake for another 1-2 hours to allow the mousse decorations to set.
  • Once fully set, remove the cake from the refrigerator, slice, and serve to dazzle your guests with a purple delight!
