I racked my brain for ideas on what dessert to make on July 4th for the past 3 months and I finally got some sense of what to make. I figured I could make a cake, but not my usual cheesecake. I wanted to make a mousse filled layered cake. Now for July 4th I want it to color coordinate. Red, white, and blue. So a white cake, a layer of strawberry mousse, and a layer of blueberry mousse. The hard part will be to figure out how to make all of this without getting in my dad’s way when he begins preparing the rest of the food for the annual July 4th party. I figured I could use a box cake mix and make the mousse and whipped cream frosting. This recipe is something that needs to be made in advance or at least a day before.
Here are the ingredients needed for this recipe:
- 8.5 oz. strawberries, sliced and divided (if using frozen allow to partially thaw)
- 4 1/2 Tbsp. sugar
- 1 Tbsp. balsamic vinegar or lemon juice
- 1/2 Tbsp. powdered gelatin (I will be using agar agar)
- 2 1/2 Tbsp. water
- 7 oz. cup heavy cream
- 5 oz. blueberries
- 4 1/2 Tbsp. sugar
- 1/2 Tbsp. lemon juice
- 1/2 Tbsp. powdered gelatin
- 2 Tbsp. water
- 7 oz. cup heavy cream
- 2 Tbsp. sugar
- 1/4 cup water
- 1 Tbsp. fruit liqueur (Optional)
Whipped Topping (Make this twice)
- 1 cup heavy cream
- 2 1/2 Tbsp. sugar
- 1/2 tsp. vanilla extract
Step 1: Prepare the cake as stated by the box directions. (I recommend making this a head of time to allow it to cool and firm up before cutting 3 layers.)
Step 1: Prepare syrup; mix water and sugar and microwave until hot, about 1 minute.
Step 2: Stir until completely dissolved, then let cool.
Step 3: Stir in fruit liqueur; set aside. (Optional)
Step 1: Begin preparing the gelatin for the blueberry/strawberry gelatin and mousse in two separate small bowls or cups; put 1 and 2 or 2 and 2 1/2 tablespoons of water in each bowl, respectively, then sprinkle the gelatin into the water and set aside.
Note: Keep heavy cream chilled.
Step 1: Put the blueberries and sugar into a food processor and purée.
Step 2: Pour the heavy cream into a large bowl and whip until thick enough that cream dribbled from the beater briefly leaves a trail, but is not stiff.
Step 3: Microwave the prepared gelatin until it turns to liquid (but don’t boil it), then add to food processor along with the lemon juice and run the food processor again to mix.
Step 4: Pour the blueberry mix into the whipping cream and fold until mixed.
Step 5: Allow to set in the refrigerator for 1 hour before use.
Step 1: Roughly slice 5 oz. of strawberries. Pour balsamic vinegar and sugar over the slices, stir to coat, and leave in a bowl to marinate for about 30 minutes. (If using lemon juice, 1 Tbsp, no need to marinate)
Step 2: Take another 3.5 oz. of strawberries, cut them in half, and slice thinly.
Step 3: Pour the marinated strawberries and any liquid into a food processor and purée.
Step 4: Pour the heavy cream into a large bowl and whip until thick enough that cream dribbled from the beater briefly leaves a trail, but is not stiff.
Step 5: Microwave the prepared 6g of gelatin until it turns to liquid, then add to food processor and mix.
Step 6: Take the sliced strawberries from 2 and the strawberry purée from 5 and add them to the whipped cream, then fold until mixed.
Step 7: Allow to set in the refrigerator for 1 hour before use.
Step 1: Warm enough strawberry jam to coat one surface of the pâte sucrée disk in the microwave to soften it, then coat the top of the tart.
Step 2: Place a cake-forming ring onto the plate the cake will be served on and line it with either acetate sheet or parchment paper. (If the ring you’re using is adjustable, size it slightly large than the tart base). Lay the base in the ring jam-side up.
Step 3: Lay the first layer of the sponge cake on top of the tart base, then dab on one third of the syrup.
Step 4: Pour the mousse strawberry onto the cake and spread smooth with a spatula.
Step 5: Lay the second layer of sponge cake onto the mousse and press down lightly, then dab on one third of the syrup.
Step 6: Pour remaining mousse on top, again spreading smooth.
Step 7: Lay the top layer of cake on top, press down lightly, and dab with remaining syrup.
Step 8: Chill for about 2-4 hours in the refrigerator to set.
Decorating The Cake
Step 1: Remove the cake ring from the cake.
Step 2: Whip one cup of heavy cream with the sugar and vanilla extract until thick enough that cream dribbled from the beater briefly leaves a trail, but is not stiff. (Here’s a video on Whipped Cream Frosting)
Step 4: Spread a thin layer of cream around the outside edge of the cake.
Step 5: Put the cake and cream in the refrigerator to allow the layer to set.
Step 6: Add another coat of cream, chill, and repeat as many times as necessary to get a nice, even layer all the way around.
Step 7: Whip the remaining cream until stiff enough to hold its shape.
Step 8: Use a pastry bag to make a decorative wall of cream around the outside edge of the top.
Step 9: Decorate with leftover fruit.
