Warm Cinnamon Apple Crisp with Golden Oat Streusel

Why This Recipe Works

  • Apple Variety Blend: Mixing tart Granny Smith with sweet crisp Honeycrisp balances flavor and texture so the filling doesn’t turn to mush.
  • Cornstarch Binding: A touch of cornstarch creates a silky, spiced syrup around the tender baked apples.
  • Cold Butter in Streusel: Cutting cold butter into the oats and flour guarantees distinct, crispy crumb clusters rather than a greasy paste.

Scale Ingredients:

Ingredients (US Customary)

  • 6 medium apples (blend of Granny Smith and Honeycrisp), peeled, cored, and sliced 1/4-inch thick
  • 2 tablespoons pure maple syrup or granulated sugar
  • 1 tablespoon fresh lemon juice
  • 1 tablespoon cornstarch
  • 1.5 teaspoons ground cinnamon
  • 0.25 teaspoon ground nutmeg
  • 1 cup old-fashioned rolled oats
  • 0.5 cup all-purpose flour
  • 0.5 cup packed light brown sugar
  • 6 tablespoons cold unsalted butter, cubed

Step-by-Step Instructions

  • 1
    Prep Oven & Filling

    Preheat oven to 350°F (175°C). Grease an 8×8-inch or 9-inch round baking dish with butter. In a large bowl, toss apple slices with lemon juice, maple syrup, cornstarch, 1 teaspoon of cinnamon, and nutmeg until well coated. Spread evenly into the baking dish.

  • 2
    Make Streusel Topping

    In a separate bowl, stir together the rolled oats, flour, brown sugar, remaining 1/2 teaspoon cinnamon, and a pinch of salt. Add cold cubed butter. Use a pastry cutter or your fingertips to work the butter in until coarse, pea-sized crumbs form.

  • 3
    Bake to Golden Perfection

    Scatter the oat topping evenly over the apples. Bake for 40 to 45 minutes until the streusel is deep golden-brown and the apple juices are bubbling warmly around the edges.

  • 4
    Cool & Serve

    Let cool for 10 minutes so the juices settle slightly. Spoon into dessert bowls and top with generous scoops of vanilla bean ice cream.

Kitchen Notes & Chef Tips

Nut Variation: Add 1/3 cup of chopped pecans or walnuts to the oat topping for extra autumnal crunch.

Reheating: Crisp in a 350°F oven for 8 minutes rather than microwaving to preserve the crunchy streusel texture.
