What is a Dessert Mousse?

A dessert mousse is a sweet and creamy dessert that is light and airy in texture. It is typically made with whipped cream or heavy cream, eggs and flavored with chocolate, fruit, or other ingredients. The key to making a good mousse is to carefully fold in the ingredients to create a smooth and velvety texture. Some mousse recipes also call for gelatin or other stabilizers to ensure that the dessert holds its shape. Mousse can be served in a variety of ways, such as in individual portions or as a cake filling.   It is a popular dessert option for special occasions, as it can be made in advance and refrigerated until ready to serve. Overall, a dessert mousse is an easy and light dessert option that is sure to impress any guest. Chocolate Mousse is the most common.




Why make a cake with Mousse filling?

Making a cake with mousse filling is the ultimate choice for those who want to indulge in a luxurious dessert experience. The light and airy texture of the mousse is a perfect complement to the cake’s denser structure, adding a layer of both flavor and texture to the final product. Mousse cake is made in a myriad of flavors, such as chocolate, vanilla, raspberry, or caramel, which can be further customized by incorporating fruits, nuts, or liqueurs. This versatile filling not only makes cakes taste decadent but also looks stunning. Layering a cake with a colorful and silky filling not only adds visual appeal but also enhances the flavor profile of the cake. It feels like a perfect treat for celebrations or special occasions. Thus, a cake with mousse filling will not only impress your guests but will also leave an unforgettable experience on their taste buds.

Chocolate and Peanut Butter Mousse Cake

Aphrodesi’hacks’ for our Peanut Butter and Chocolate Mousse Cake

  • For this Mousse cake recipe:   We recommend regular chocolate cake mix, rather than one of the ‘Super Moist’ varieties.  The Peanut Butter mixture already gives the cake plenty of moisture.
  • Reese’s Pieces can be spread evenly on top of the cake for additional color.
  • Peanut Butter Chocolate is a combination that can become too soft, and the cake may lose its fresh and beautiful look.  Chill before serving
  • Short on Reese’s cups?  Mix up the look by only putting candy on top.
  • Make the chocolate cake the night before, for easy assembly the day of the party.




Mix it Up with our Chocolate and Peanut Butter Mousse Cake

  • This Peanut Butter Mousse is amazing. Fast and easy to make…Put it in dessert cups and serve with a few mini Reese’s cups on top.  Voila!
  • Sprinkle Reese’s Pieces on top of the cake for additional color
