Apple Crumb Cookie Bars

You are not ready for these Apple Crumb Cookie Bars! With a slightly cakey sugar cookie base, a warm brown sugar apple filling, and a jaw dropping crumble topping, I am floored by these.

  • 1 cup (222g) salted butter, softened
  • 2/3 cup (162g) brown sugar
  • 1/3 cup (76g) granulated sugar
  • 2 eggs
  • 2 tsp vanilla extract
  • 2 tsp molasses
  • 3 1/4 cups (494g) all-purpose flour
  • 2 tsp baking powder
  • 1/2 tsp salt

Apple Filling

  • 4 cups diced apples (About 5 medium apples)

  • 1 1/2 tsp cinnamon

Crumble Topping

  • 1 cup reserved cookie dough
  • 1/2 cup (50g) rolled oats
  • 2 Tbsp brown sugar

Instructions

  • Start by making the apple filling. In a sauté pan over medium heat, melt the butter.
    4 Tbsp salted butter
  • Once melted, add the diced apples (¼-inch pieces), brown sugar, cornstarch, and cinnamon. Cook, stirring frequently, for 8–10 minutes, until the apples are fork-tender. Set aside.

  • Preheat the oven to 350°F (180°C) and line a 9×13 pan with parchment paper, leaving overhang for easy removal.
  • To make the cookie dough, cream the butter and sugars in a stand mixer until light and fluffy. This will take about 2 minutes.
    1 cup (222g) salted butter, softened, 2/3 cup (162g) brown sugar, 1/3 cup (76g) granulated sugar
  • Scrape down the bowl, and add the eggs, vanilla, and molasses; mix until combined.
    2 eggs, 2 tsp vanilla extract, 2 tsp molasses
  • Once combined, add the flour, baking powder, and salt and mix just until a dough forms.
    3 1/4 cups (494g) all-purpose flour, 2 tsp baking powder, 1/2 tsp salt
  • Remove 1 cup of dough and set aside for the crumble topping. Press the remaining dough evenly into the prepared pan.
  • Spread the apple filling evenly over the dough.
  • Make the crumble by adding the oats, brown sugar, and cinnamon to the reserved cookie dough. Mix until combined.

  • Crumble the topping over the apples, leaving some filling visible.
  • Bake for 22–26 minutes, or until the topping is lightly browned.
  • Cool completely before removing from the pan and slicing.
  • Store in an airtight container at room temperature for 3–5 days. This is best enjoyed the first day for the crunchiest topping.
