For the apple filling:

  • 4 granny smith apples peeled & cubbed
  • 3 tablespoons butter
  • 1/4 cup brown sugar
  • 1/2 teaspoons cinnamon
  • Pinch ground nutmeg
  • 1/2 lemon juiced
  • 1 tablespoons cornstarch

For the oat crumble:

  • 1/2 cup all-purpose flour
  • 1/2 cup whole wheat flour
  • 1 cup old fashioned oats
  • 1/2 cup light brown sugar
  • ΒΌ teaspoon kosher salt
  • 1/2 teaspoon cinnamon
  • 1/4 teaspoon ground nutmeg
  • Pinch ground cloves
  • 6 tablespoons butter softened
  • 2 tablespoons honey
  • 1 tablespoon heavy cream


  • In a medium saucepan, combine the butter and sugar together over low heat. Add the apples, cinnamon, nutmeg and lemon and stir. Turn the heat up to medium and let the mixture simmer for about 10-15 minutes or until thickened.
  • Whisk in the cornstarch, smoothing out any lumps, then remove from the heat. Let cool as completely as possible before assembling the bars.
  • Line an 8x8" pan with parchment paper and preheat the oven to 350 degrees F.
  • Combine the flours, oats, sugar, salt + spices in a bowl. Add the butter and honey and use your fingers to combine into a crumbly mixture. Add cream and continue to work the dough with your hands. Pour 3/4 of the mixture into your prepared pan, firmly pushing it down evenly and into the corners.
  • Spread the apple filling on top, then sprinkle the remaining crumble across the fruit mixture. Bake for 35-40 minutes or until lightly golden brown. Remove from the oven and let the bars cool completely in the pan before slicing and serving (otherwise they may be too soft and fall apart). Keep in the fridge until ready to eat.


Storing: Leftover apple crumble bars can be stored in an airtight container in the fridge for 4-5 days.
Freezing: To freeze, wrap any completely cooled apple crumb bars in plastic wrap, then again in aluminum foil. Add them to an airtight container or freezer-safe bag and freeze for 3-4 months. Thaw overnight in the fridge before serving.
