Ingredients You Need for Oatmeal Cookie Apple Crisp

For the Apple Filling:

• 6 medium apples (I prefer mixing Granny Smith and Honeycrisp for the perfect texture balance)
• 1/3 cup brown sugar (adds that lovely caramel sweetness)
• 1 tablespoon all-purpose flour (helps thicken the juices beautifully)
• 1 teaspoon ground cinnamon (the classic apple spice)
• 1/4 teaspoon ground nutmeg (adds warmth and depth)
• 1/4 teaspoon vanilla extract (my secret ingredient for extra flavor)
• Pinch of salt (brings out all the flavors)

For the Oatmeal Cookie Topping:

• 1 cup old-fashioned oats (rolled oats work best here)
• 3/4 cup all-purpose flour
• 2/3 cup brown sugar (packed for sweetness)
• 1/2 cup cold unsalted butter (cubed – this is key for the perfect crumble)
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon salt
• 1/3 cup chopped pecans (optional, but I highly recommend them!)

Substitution Tips: You can swap the pecans for walnuts or almonds, and if you don’t have nutmeg, just use extra cinnamon.

For a gluten-free version, substitute the flour with your favorite gluten-free blend.

How to Make Oatmeal Cookie Apple Crisp

Step 1: Preheat your oven to 350°F (175°C) and lightly grease a 9×9 inch baking dish. I always use butter for greasing because it adds extra flavor.

Step 2: Peel, core, and slice your apples into thin wedges – about 1/4 inch thick works perfectly. I like to keep them uniform so they cook evenly.

Step 3: In a large mixing bowl, toss the sliced apples with brown sugar, flour, cinnamon, nutmeg, vanilla, and salt until every piece is well coated. The flour will help create a lovely sauce as it bakes.

Step 4: Transfer your seasoned apples to the prepared baking dish, spreading them out evenly. This creates the perfect base for your oatmeal cookie topping.

Step 5: For the topping, combine oats, flour, brown sugar, cinnamon, and salt in another bowl. Add the cold, cubed butter and use your fingers or a pastry cutter to work it in until the mixture resembles coarse crumbs with some larger butter pieces. Stir in the pecans if using.

Step 6: Sprinkle the oatmeal crumble evenly over the apples – don’t pack it down! You want it to stay light and crispy.

Step 7: Bake for 40-45 minutes until the topping is golden brown and the apples are tender when pierced with a fork. The edges should be bubbling beautifully.

Step 8: Cool for at least 10 minutes before serving – this helps the filling set up perfectly.

My Favorite Tips for Getting That Perfect Golden Crumble

My biggest tip is to use cold butter for the topping – it creates those perfect crumbly pieces that make each bite so satisfying!

I always keep some apple varieties that hold their shape well, like Granny Smith, mixed with softer ones for the best texture.

Don’t skip the resting time after baking; it really makes a difference in how the flavors meld together.

What apples work best for this recipe?

I love using a mix of Granny Smith apples for their tartness and firm texture, combined with Honeycrisp or Gala for sweetness.

This combination gives you the perfect balance of flavors and textures in every bite.

Can I make this Oatmeal Cookie Apple Crisp ahead of time?

You can assemble the entire crisp up to a day ahead and refrigerate it.

Just add 5-10 minutes to the baking time if you’re starting from cold. I often prep mine in the morning for evening dessert.

Can I freeze leftover apple crisp?

Yes! Wrap individual portions tightly and freeze for up to 3 months.

Reheat in a 350°F oven for about 15 minutes until warmed through. The texture stays surprisingly good.

How do I prevent a soggy bottom?

Make sure to toss your apples with flour – this helps absorb excess juices. Also, don’t skip the resting time after baking, as this allows the filling to thicken properly.
