Ingredients (Serves 6)

For the filling:

  • 5–6 medium apples (Honeycrisp, Gala, or Granny Smith), peeled and sliced
  • 2 tbsp lemon juice
  • ¼ cup brown sugar
  • 2 tbsp granulated sugar
  • 1 tsp cinnamon
  • ¼ tsp nutmeg
  • 1 tsp vanilla extract
  • 1 tbsp cornstarch
  • For the topping:
  • ¾ cup old-fashioned oats
  • ½ cup all-purpose flour
  • ½ cup brown sugar
  • ½ tsp cinnamon
  • ¼ tsp salt
  • 6 tbsp cold butter, cubed

Instructions

Preheat oven: to 350°F (175°C). Lightly grease a 9×9-inch baking dish.

Make the filling: In a large bowl, toss the sliced apples with lemon juice, both sugars, cinnamon, nutmeg, vanilla, and cornstarch. Spread evenly in the baking dish.

Make the topping: In another bowl, mix oats, flour, brown sugar, cinnamon, and salt. Add cold butter and use your fingers or a pastry cutter to blend until crumbly.

Assemble: Sprinkle the topping evenly over the apples.

Bake: 40–45 minutes, until the topping is golden brown and the filling is bubbling around the edges.

Cool slightly: Let sit for 10 minutes before serving.

Serving Suggestion

Serve warm with a scoop of vanilla ice cream or a drizzle of caramel sauce. It also pairs beautifully with whipped cream and a hot cup of coffee or apple cider.
