Apple Custard Bars

In-season apples get thinly sliced and baked into a thick, creamy custard for these easy bars. Light yet satisfying, they’re versatile enough to serve for breakfast, dessert, or an afternoon snack.
Prep Time: 20 minutes

Ingredients

  • 1 ¼ cups whole milk
  • 4 large eggs
  • ½ teaspoon kosher salt
  • 1 tablespoon vanilla extract
  • ½ cup sugar
  • ½ cup all-purpose flour
  • 3 medium apples any variety, peeled
  • powdered sugar for dusting optional

Instructions

  1. Preheat the oven to 375°F and line an 8x8-inch square baking dish with parchment paper.
  2. Add the milk to a large bowl or blender along with the eggs, salt, vanilla extract, sugar and flour.
  3. Blend until smooth using either a blender or immersion blender, for about 30 seconds. You can whisk by hand, but make sure the mixture is completely smooth before proceeding.
  4. Using a mandoline slicer or very sharp knife, slice the apples around the core as thinly and evenly as possible. The thinner the apple slices, the more tender they will be once baked. Discard the cores.
  5. Add the apples to the batter and stir with a rubber spatula until combined.
  6. Transfer batter to the parchment lined pan, then use the spatula to smooth out the top and make sure the apples are evenly dispersed.
  7. Bake for about 30 minutes, or until golden brown, puffed, and mostly set in the center (a slight jiggle is perfect). Do not overbake or the custard will turn rubbery.
  8. Let cool at room temperature, then pop them in the refrigerator to chill completely before slicing.
  9. Dust all over with powdered sugar (optional), then cut the bars into 9 large or 16 small squares.
  10. Serve bars chilled (my preference) or at room temperature. They will keep refrigerated for up to 1 week.

Notes

  • Don’t overbake or the eggs will turn rubbery.
  • Slice apples as thinly as possible for the most tender texture.
  • Chill completely before cutting to get clean, even slices.
  • Use parchment paper for easy removal and less mess.
