  • Total Time: 9 hours 40 minutes
  • Yield: 12 1x

Ingredients

Scale
  • 1 cup powdered sugar plus more for garnish
  • 16 ounces softened cream cheese divided
  • 2 teaspoons grated lemon zest plus 1½ tablespoons fresh lemon juice, divided
  • 1 tablespoon plus 1 teaspoon vanilla extract divided
  • 2 cups mixed berries divided
  • â…” cup granulated sugar
  • 2 cups half-and-half
  • 4 large eggs lightly beaten
  • ½ teaspoon kosher salt
  • 14 mini croissants*
  • toasted sliced almonds for topping
  • maple syrup for serving

Instructions

  1. In a large mixing bowl, combine the powdered sugar with 8 ounces of the cream cheese. Add the lemon zest, ½ tablespoon lemon juice, and 1 teaspoon vanilla. Mix until smooth and creamy. Gently fold in half the berries, pressing some to release their juices. Set aside.
  2. In another bowl, blend the remaining cream cheese with granulated sugar until smooth. Slowly whisk in half-and-half, then add eggs, salt, remaining lemon juice, and vanilla. Mix until silky.
  3. Slice croissants in half horizontally and arrange the bottom halves in a greased 9Ă—13-inch baking dish. Spoon the berry cream cheese mixture over each half, then place the top halves back on to create sandwiches.
  4. Pour the custard mixture evenly over the croissants, ensuring everything is soaked. Tear remaining croissants into pieces and tuck them into open spaces. Scatter remaining berries on top.
  5. Cover the dish and refrigerate for at least eight hours or overnight to absorb flavors.
  6. When ready to bake, let the dish sit while preheating the oven to 325°F. Cover with foil and bake for about 30 minutes, then remove foil and bake for another 25 to 30 minutes until golden and set.
  7. Finish with a sprinkle of toasted almonds and powdered sugar. Serve warm with maple syrup.
