Author Notes

This dessert combines the simplicity and ease of a trifle with the deliciousness of a frozen dessert. The dessert is built in layers, but you don’t have to wait for each layer to freeze before you add the next. Plus, individual trifles freeze fast, which means you’re getting to your chilly treat way quicker. The semifreddo is super flexible. I made two flavors for mine, using blackberry and blueberry, but nearly any fruit can be used here following the same method. The ingredients for the trifle can be swapped out, too, so you can mix up the cake and cookie types and flavors to match your semifreddo and create your own layered wonder! —Erin Jeanne McDowell

What You'll Need
  • 8 ounces (226 g) blackberries
  • 8 ounces (226 g) blueberries
  • 1 medium lemon, halved
  • 1 vanilla bean, halved
  • 1/2 cup (99 g) granulated sugar, divided
  • 2 cups (455 g) heavy cream
  • 1 1/3 cups (151 g) powdered sugar
  • 1 cup (227 g) sour cream, divided
  • 1/2 angel food cake, diced (homemade or store-bought)
  • 8 ounces (226 g) bite size meringue cookies
  1. Place the blackberries in a medium pot, and place the blueberries in a second medium pot. Squeeze half of the lemon into each pot, place half of the vanilla bean into each pot, and sprinkle 1/4 cup sugar into each.
  2. Bring the berries to a simmer over medium heat, stirring occasionally, until the berries have completely broken down and are very soft, 15-18 minutes.
  3. Strain each mixture into separate bowls. You’ll need ½ cup of each fruit puree. If you have more than 1/2 cup, you can return the puree to the pot and bring to a simmer. Simmer for 10-15 minutes to reduce it slightly to concentrate the flavors. The purees don’t need to cool completely before you use them, but letting it cool for at least 15 minutes will make the process easier (and allow the trifles to freeze faster later)!
  4. In the bowl of an electric mixer, beat the cream and powdered sugar to medium peaks, 3-4 minutes.
  5. For each semifreddo recipe, you’ll use 1/2 cup fruit puree, 1/2 cup sour cream, and half of the whipped cream mixture. In a large bowl, whisk the blackberry puree and ½ cup sour cream together to combine, then gently fold in half of the whipped cream. Repeat with the blueberry puree.
  6. Building the trifles is super free form; you can do it in any order you like, alternating the two flavors of semifreddo with the meringues and angel food cake. I like to start with one of the semifreddos, then alternate between the meringues and angel food cake. Spoon the first flavor of semifreddo into a medium glass, then sprinkle a layer of meringues and/or angel food cake (press them into the semifreddo a little bit). Then spoon the other flavor of semifreddo into the glass, continue this until the glass is completely full, and repeat until you’ve used up all your components and filled all your glasses.
  7. Freeze the trifles until the top layer is firm; this can be as little as 30 minutes and as much as 1 1/2 hours, depending on how hot it was when you built it and how cold your freezer runs. Let the trifles sit at room temperature for up to 5 minutes before serving.

I always have three kinds of hot sauce in my purse. I have a soft spot for making people their favorite dessert, especially if it's wrapped in a pastry crust. My newest cookbook, Savory Baking, came out in Fall of 2022 - is full of recipes to translate a love of baking into recipes for breakfast, dinner, and everything in between!
