Ingredients:

  • 2 cups (300g) fresh apples, peeled and finely diced
  • 2 tbsp (25g) unsalted butter
  • 3 tbsp (35g) brown sugar
  • 1 tsp (2g) ground cinnamon
  • 1 tbsp (8g) cornstarch
  • 2 1/4 cups (280g) all-purpose flour
  • 3/4 cup (170g) unsalted butter, softened
  • 3/4 cup (150g) packed brown sugar
  • 1 large egg
  • 1 tsp (5ml) vanilla extract
  • 1 tsp (5g) baking soda
  • 1/2 tsp (3g) salt
  • 1/2 cup (60g) all-purpose flour
  • 1/2 cup (45g) rolled oats
  • 1/4 cup (50g) brown sugar
  • 3 tbsp (42g) unsalted butter, melted
  • 1/4 tsp (1g) salt

Instructions:

  1. Melt 2 tbsp butter in a skillet over medium heat. Add diced apples, brown sugar, and cinnamon. Cook for 3–5 minutes until translucent. Stir in cornstarch and cook for 1 more minute until thick. Remove from heat and let cool.
  2. Cream the softened butter and brown sugar until pale and fluffy. Beat in the egg and vanilla. Fold in the flour, baking soda, and salt until just combined.
  3. In a separate bowl, stir together flour, oats, brown sugar, and salt. Pour in melted butter and stir until coarse, buttery clumps form.
  4. Preheat oven to 350°F (175°C). Scoop 1 tbsp of cookie dough and flatten slightly on a baking sheet.
  5. Place a small spoonful of apple filling in the center, pressing down. Cover with another small piece of dough or leave open-faced, then press a generous pinch of oat crumble on top.
  6. Bake for 10–12 minutes until the edges are golden brown and the crumble is toasted.
