Ingredients

Apple Filling

  • 6 cups peeled and chopped Granny Smith apples (720g, about 4 to 5 medium sized apples)
  • 2 tbsp all purpose flour (16g)
  • 1/2 cup light brown sugar, tightly packed (120g)
  • 1 tbsp lemon juice
  • 1/2 tsp salt
  • 1 tsp cinnamon

Peanut Butter Oat Crumble Topping

  • 1 cup flour (130g)
  • 1 cup old-fashioned rolled oats (120g)
  • 3/4 cup light brown sugar, tightly packed (150g)
  • 1/2 teaspoon cinnamon
  • 1/2 tsp salt
  • 10 tbsp unsalted butter, melted (140g)
  • 1/4 cup peanut butter (60g) – preferably creamy

Assembly

  • 1/4 cup peanut butter, melted (60g)

Instructions

  1. Prepare the Apple Filling: Preheat your oven to 375°F (190°C, conventional/non-fan). Grease a 7×11-inch baking dish with butter. Chop the Granny Smith apples into small cubes roughly the size of blueberries. In a large bowl (or directly in the baking dish), combine the apples with flour, brown sugar, lemon juice, salt, and cinnamon. Toss everything together until the mixture is evenly combined.
  2. Make the Peanut Butter Oat Crumble Topping: In a separate bowl, mix together the flour, rolled oats, light brown sugar, cinnamon, and salt. Melt the butter in the microwave in 20-second increments until fully liquefied. Stir in the peanut butter to the melted butter until smooth; if the peanut butter is too firm, microwave for an additional 10-15 seconds. Pour this wet mixture over the dry ingredients and combine using a spoon with a stir and press motion until the mixture holds together into a thick, crumbly texture slightly softer than pie dough. Be careful not to overmix or make it smooth.
  3. Assemble and Bake: Transfer the apple filling to your prepared baking dish if not already combined there. Drizzle the 1/4 cup of melted peanut butter evenly over the apples. Using your fingers, sprinkle the peanut butter oat crumble topping in uneven chunks over the apple layer, allowing some apples to peek through for a crispier texture. Bake for 40-45 minutes until the crumble is golden brown and crispy and the apples are soft and jammy (test by piercing with a fork).
  4. Serve: Let the apple crisp cool slightly before serving warm. It pairs wonderfully with vanilla ice cream or plain whipped cream for added texture contrast without extra sweetness.

Notes

  • Apple Type: Granny Smith apples provide a perfect balance of tartness and sweetness and hold up well when baked. Honeycrisp apples are a suitable alternative.
  • Oat Choice: Use old-fashioned rolled oats for the best texture. Instant oats can be substituted but may result in a different crumble consistency.
  • Baking Dish: A 7×11-inch ceramic or glass baking dish is ideal for thickness and even cooking. You may use 8×8, 9×9, or similar sized dishes, but a larger 9×13-inch dish will yield a thinner crisp that bakes faster (around 35-40 minutes).
  • Storage: Bake within a few hours of assembly to prevent apple browning. Store baked apple crisp at room temperature for up to 1 day or refrigerate for up to 5 days. Reheat in the microwave before serving.
