Ingredients

Filling:

  • 4 cups sliced bananas* sliced ½-¾ inch thick
  • 2 tablespoons apple juice
  • 3 tablespoons brown sugar
  • 1 tablespoon all purpose flour
  • ¾ teaspoon pure vanilla extract

Topping:

  • 1 cup all purpose flour
  • ½ cup granulated sugar
  • ¼ cup light brown sugar
  • ¼ teaspoon kosher salt
  • ½ cup cold unsalted butter cut into cubes
  • cup chopped macadamia nuts (preferably roasted salted)**
  • vanilla ice cream and salted caramel sauce for serving

Instructions

  • Preheat oven to 375°F with a rack in the center of the oven. Lightly grease an 8x8 square or 9-inch deep dish pie plate. Set aside.
  • For the filling: In a large bowl combine all ingredients. Stir gently until combined. Dump the mixture (and any accumulated juices) into the prepared baking dish and spread into an even layer.
  • For the topping: combine flour, both sugars, and salt. Add cubed butter (it should be cold). With a pastry cutter, or using your fingers, cut/rub the butter into the flour mixture until it is in small pebble-sized pieces and resembles clumpy sand. Using your fingers, crumble the mixture over the bananas, occasionally pressing some of it together to form clumps.
  • Bake for about 20 minutes, until the topping is light golden brown. Cool slightly, serve warm with vanilla ice cream and caramel sauce.

Notes

*Bananas: You will need about 4 medium-large bananas. Bananas should be just barely ripe. When baking with bananas you typically want over-ripe bananas, but not for this recipe. Overripe bananas will get mushy, so ripe-firm bananas are best.
**Macadamia nuts: The macadamia nuts are non-negotiable. If I'm being honest, the macadamia nuts are just as important as the banana. They are the star of this recipe and they take it from good to GREAT. Roasted salted macadamia nuts work best. They are extra crunchy and the added salted balances all the sweetness. My favorite macadamia nuts are from Target (on the nuts/trail mix aisle).
