For the crust:
all purpose flour
rolled oats
brown sugar
melted butter
salt

For the apple filling:
apples (peeled and diced)
sugar
lemon juice
cinnamon
cornstarch

For the crisp topping:
rolled oats
brown sugar
flour
cold butter cubed

Directions

Preheat the oven to 350°F (175°C) and prepare an 8×8 baking pan by lining it with parchment paper.
Mix the crust ingredients (flour, oats, brown sugar, melted butter, salt) until combined, then press about two‑thirds of the mixture firmly into the bottom of the pan to form the base.
In a bowl, toss the diced apples with sugar, lemon juice, cinnamon, and cornstarch until evenly coated. Spread this apple mixture in an even layer over the crust.
Combine the crisp topping ingredients (oats, brown sugar, flour, cold butter) until crumbly, then sprinkle over the apples.
Bake for about 35–40 minutes or until the topping is golden and the apples are tender and bubbly.
Allow the bars to cool completely before cutting into squares and serving.

Variations

Add chopped nuts (like walnuts or pecans) to the topping for extra crunch.
Mix in spices like nutmeg or allspice with the cinnamon for deeper flavor.

Storage/Reheating

FAQs

What type of apples should I use?

Firm apples like Fuji, Honeycrisp, or Granny Smith work best because they hold their shape and offer a nice balance of sweet and tart flavor.

Can I make this recipe gluten‑free?

Yes, you can substitute gluten‑free flour and gluten‑free oats to make gluten‑free apple crisp bars.

Do I need to peel the apples?

Peeling is recommended to give a smoother texture in the bars, but you can leave the skins on if you prefer more texture and fiber.

Can I use frozen apples?

You can use frozen apples, but make sure to thaw and drain excess liquid before mixing with sugar and spices.

How do I get clean slices?

Letting the bars cool completely before cutting helps ensure cleaner slices without the filling falling apart.

Can I prepare the bars ahead of time?

Yes! You can assemble and refrigerate before baking or bake and then reheat gently in the oven when ready to serve.

Can I double the recipe?

Absolutely. Use a larger pan (like 9×13) and adjust baking time slightly if needed.

What’s the best way to reheat leftovers?

Warm in a preheated 300°F oven for 10–15 minutes until heated through.

Can I add caramel sauce?

Yes, drizzle warm caramel over the bars after baking for a richer dessert.

Will the crumble topping stay crunchy?

The crunchiness can soften over time; storing at room temperature or briefly reheating can help maintain texture.

Conclusion

These Apple Crisp Bars are a comforting and delicious twist on a classic dessert, combining tender spiced apples with a buttery oat topping. Whether for a cozy night in or a treat to share, they’re sure to become a favorite.
