I recently tried making my version of Apple Crisp With Streusel Topping and it quickly became a standout treat. I blended diced apples with a touch of cinnamon and lemon juice and set them on a buttery shortbread crust. Topped with an oat streusel and drizzled with caramel, it is an irresistible fall treat.

I recently stumbled upon a twist on a classic treat that I just had to share – Apple Crisp Bars with a lush streusel topping and a tender shortbread crust. I mixed 2 cups all purpose flour, 1/2 cup granulated sugar, and 1/2 cup cold unsalted butter for my base, which really sets the stage for something special.
In the filling, I tossed around 5 cups of peeled, diced apples with a sprinkle of 1/2 cup granulated sugar, 1/2 teaspoon ground cinnamon, a dash of 1/4 teaspoon nutmeg and 2 teaspoons lemon juice to brighten things up. The streusel topping was a fun mix of 3/4 cup flour, 3/4 cup old fashioned oats, and 1/2 cup packed brown sugar all brought together with melted butter and a pinch of cinnamon.
Drizzling 1/2 cup caramel sauce on top drives home those apple crisp vibes while making it a perfect after school bite.
Why I Like this Recipe
I love how the shortbread crust gives the bars a satisfying crunch and that buttery flavor which contrasts perfectly with the soft, spiced apple layer. I really like the mix of spices too – the cinnamon and nutmeg make me think of cozy autumn days and it just warms me up inside. The streusel topping is a game changer; its oats and brown sugar add this extra texture that makes every bite super interesting. And the caramel drizzle on top? It’s like a little burst of sweetness that ties everything together and makes me feel like I’m treating myself every time I have a bite.

FAQ
Apple Crisp Bars Recipe Substitutions and Variations
- All purpose flour (for the crust): You can try using whole wheat flour instead, just do a 1 to 1 swap though it might make the crust a bit denser.
- Unsalted butter (for the crust): If you are out or want a different flavor, you could use coconut oil or shortening but keep in mind the taste and texture could change slightly.
- Granulated sugar (for the apple filling): Honey or maple syrup can be used instead, but reduce a little liquid elsewhere in the recipe to keep the consistency right.
- Old fashioned oats (for the streusel topping): Quick oats work well as a substitute, however they might give a slightly different crunch to the topping.
Pro Tips
1. Make sure you use really cold butter when you make your shortbread crust so it stays crumbly and doesn’t get too soft when you mix it in.
2. Don’t overmix the streusel topping since if you work the butter too much, it might become gloopy and won’t create that nice crunchy texture on top.
3. Let the baked bars cool completely before cutting them up, cause if they’re too warm they might fall apart or become a sticky mess.
4. For extra even baking, try rotating your pan halfway through the cooking time so all parts get the same golden-brown goodness.
