Chantilly Cake Filling and Frosting
Berries can be expensive, so instead of using fresh berries, I made this Chantilly Cake with two bags of frozen mixed berries cooked down into a quick fruit compote. For the cake itself, I used the original version of King Arthur Baking Company Elegant White Cake, but you can pair this filling and frosting with almost any white cake recipe you like.

Ingredients
Mixed Berry Compote
- 5 cups frozen mixed berries (24 oz)
- ½ cup sugar
- 2-3 teaspoons cornstarch
- 1 tablespoon cold water
- 1 ½ tablespoons lemon juice
Chantilly Frosting
- 8 oz cream cheese, softened
- 2 cups plus 2 tablespoons powdered sugar
- 8 oz mascarpone cheese
- 2 cups cold heavy cream
- 2-3 teaspoons vanilla extract
Instructions
- Prepare the compote ahead of time so it has plenty of time to cool and thicken.
- Put the frozen berries in a large saucepan. If the strawberries are very large, slice them while still partially frozen.
- Add the sugar and cook over medium heat, stirring often, until the berries thaw and the sugar dissolves.
- Mix the cornstarch with the cold water and stir it into the berry mixture. Cook, stirring constantly, until the juices thicken slightly. Remove from heat and stir in the lemon juice.
- Transfer the compote to a bowl and let cool completely, then refrigerate until cold. The mixture will thicken slightly as it chills.
Chantilly Frosting
- With the paddle attachment, beat the cream cheese until soft and creamy. Add the powdered sugar and stir (still with the paddle) on a low speed until mixed. Increase speed to medium and beat just until it is lump free.
- Add the mascarpone and stir on low speed until smooth, then pour in the cream. Stir on lowest speed until smooth, increasing if needed, but do not beat. The goal is just a big bowl of creamy cheese and cream.
- Remove bowl from the stand, cover and chill until ready to assemble.
- When ready to assemble, add the vanilla.
- Use the whisk attachment to beat the cream mixture just until stiff peaks start to form.
