  2. Whisk the egg whites until they form soft peaks.
  3. In another bowl, combine the milk, melted butter, and cake mix, stirring until fully incorporated.
  4. Gently fold in the beaten egg whites to create a light and airy batter.
  5. Pour the batter into the prepared pan and bake for 12-15 minutes until golden.
  6. Let the cake cool slightly before dusting with powdered sugar and flipping it onto a new sheet of parchment.
Making the Mousse Filling
  1. Melt the white chocolate over a double boiler until smooth and cool slightly.
  2. Whip 1 cup of heavy cream until soft peaks form, then fold in the cooled chocolate.
Filling and Rolling the Cake

  2. Roll the cake from one end to the other and refrigerate for a minimum of 30 minutes.
Serving
  1. Sprinkle crushed M&M’s on top and slice into generous portions.
  2. Serve with additional whipped cream if desired.
