Chocolate Madeleines12, crumbled (Recipe here) Your favorite brownie recipe would work, too.
Pastry Cream2 cups (Recipe here. I doubled for 4 servings. Note: If you double the recipe just use 5 tablespoons sugar instead of 6)(I also recommend using vanilla bean paste instead of vanilla extract for richer vanilla flavor)
Fresh blueberriesabout 1 1/2 cups for 4 servings
Caramelhome-made or store-bought. I used 1-2 tablespoons per serving
Prepare all the individual components. Wait for the madeleines (or brownies) and the pastry cream to cool to room temperature before using.
