Ingredients for apple crisp recipe with cake mix and pie filling

Pantry staples meet bakery magic—just 12 ingredients for a crisp that tastes homemade.

The apples are your flavor foundation—Honeycrisp or Fuji work best for that perfect balance of sweetness and tartness. Trader Joe's or Whole Foods always have the freshest selection, but any crisp apple from the grocery store will do. Skip the red ones—they can turn mushy. For extra caramelization, toss the sliced apples with a pinch of cinnamon before assembling. The pie filling? Mott's or Libby's unsweetened apple is my go-to—it's got that perfect spice blend without being too sweet. If you can't find unsweetened, just reduce the sugar in the topping slightly.

No vanilla cake mix? Spice cake mix works too, but skip the extra spices in the topping. Out of oats? Crushed graham crackers or digestive biscuits make a great crunchy substitute. The butter matters here—cold cubed butter gives you those perfect golden-brown pockets. If you're worried about the topping being too sweet, cut the brown sugar to 1/3 cup and add 1/4 cup of flour to the crumble mix. For the walnuts, toast them in a dry pan for 3-4 minutes until fragrant—that aroma is everything. No walnuts? Pecans or almonds work just as well.

This crisp keeps beautifully—3-4 days at room temperature if you can resist eating it all. For leftovers, store in an airtight container in the fridge. The topping stays crispy for about 2 days that way. Freeze portions if you're making this ahead—up to 3 months. Just bake straight from frozen, adding 10-15 minutes to the cooking time. The filling stays gooey when reheated, so it's perfect for quick dessert fixes. Serve warm with that vanilla ice cream, and you'll forget it was ever store-bought.

Step-by-step instructions for apple crisp with cake mix and pie filling

Here's how to build this dreamy dessert with minimal effort but maximum flavor.

In a large bowl, combine the 4 medium fresh apples (already peeled, cored, and sliced thin) with the 1 can store-bought pie filling. Stir gently with a wooden spoon until the apples are evenly coated in the filling mixture. This step ensures every bite has that perfect balance of fresh apple flavor and sweet filling.

For best results, I like to let this mixture sit at room temperature for 10-15 minutes before baking. This allows the apples to soften slightly and release some juices, which helps create a moister final texture. If you're using a particularly tart apple variety, you might want to add 1-2 teaspoons of granulated sugar from the topping mix to balance the flavors.

In a separate large bowl, create the crisp topping by combining the 1 box vanilla cake mix, 1 cup old-fashioned oats, 0.5 cup brown sugar, 1 tablespoon ground cinnamon, 0.5 teaspoon salt, 0.25 cup granulated sugar, and 0.5 cup chopped walnuts. Mix these dry ingredients together with your hands or a fork until evenly distributed—you should see a crumbly texture with visible walnut pieces throughout.

Next, cut the 0.5 cup unsalted butter into small cubes and work them into the dry mixture using your fingers or a pastry cutter. Press the butter pieces into the oat mixture until you achieve a coarse, pebbly texture with butter pieces ranging from pea-sized to dime-sized. This creates that signature crispy, crunchy texture we all love in apple crisp. If the mixture seems too dry, add 1 teaspoon of vanilla extract to help bind it together.

Preheat your oven to 375°F and grease a 9x13-inch baking dish with nonstick spray or butter. Spread the apple filling mixture evenly across the bottom of the prepared dish, pressing down gently to create an even layer. This ensures the filling cooks uniformly and prevents any pockets of raw apple.

Sprinkle the crisp topping mixture evenly over the apple filling, pressing down lightly with your fingers or the back of a spoon. The topping should cover the filling completely, with no gaps showing. Bake in the preheated oven for 35-40 minutes, until the topping is deep golden brown and the filling is bubbling vigorously around the edges. The center should still have some slight jiggle—it will continue cooking as it rests.

Remove the apple crisp from the oven and let it cool for 15-20 minutes before serving. This resting period allows the filling to set slightly and the juices to redistribute, preventing a runny dessert. The crisp should be warm but not hot—just right for scooping up that delicious filling.

For the ultimate presentation, serve each slice warm with a generous scoop of 1.5 cups vanilla ice cream on the side. The contrast between the warm, spiced crisp and the cool, creamy ice cream is what makes this dessert truly special. Store any leftovers in an airtight container in the refrigerator for up to 3 days, though I doubt it'll last that long!

Dietary considerations for this recipe

Gluten-Free Adaptations

Skip the vanilla cake mix and replace it with a 1:1 gluten-free vanilla cake mix like Betty Crocker Gluten Free or King Arthur Measure for Measure. Use certified gluten-free oats (like Bob's Red Mill) instead of regular oats—regular oats often contain cross-contamination.
