These apple crisp bars take everything you love about classic apple crisp and make it portable. The same buttery oat mixture is used for both the base and the crumble topping, sandwiching a cinnamon-spiced apple layer.
This is the kind of recipe that defines American home cooking at its best — straightforward, satisfying, and built on flavors that everyone loves.
Ingredients
- 4 medium apples, peeled and diced
- 2 cups old-fashioned oats
- 1 cup all-purpose flour
- 3/4 cup brown sugar, packed
- 3/4 cup butter, cold and cubed
- 1 1/2 tsp cinnamon, 1/4 tsp nutmeg
Instructions
- 1
Toss diced apples with 1/4 cup brown sugar, 1 tsp cinnamon, nutmeg, and 1 tbsp lemon juice. Set aside.
- 2
Combine oats, flour, remaining brown sugar, remaining cinnamon, and a pinch of salt. Cut in cold butter until crumbly.
- 3
Press two-thirds of the oat mixture firmly into the bottom of a parchment-lined 9x13 pan.
- 4
Spread the apple mixture evenly over the crust. Crumble the remaining oat mixture on top.
- 5
Bake at 350°F for 35-40 minutes until the top is golden and the apples are bubbling. Cool completely before cutting into bars.

Tips & Storage
Pro Tips
Use firm apples like Granny Smith or Honeycrisp that hold their shape during baking.
Cool completely in the pan before cutting—warm bars will crumble instead of slicing cleanly.
Measure baking ingredients by weight when possible. Baking is chemistry, and precision matters more than in any other type of cooking.
Bring butter, eggs, and dairy to room temperature before mixing. Cold ingredients do not emulsify properly and can produce tough, uneven results.
Storage
Store in an airtight container at room temperature for 3 days or refrigerate for a week.
Reheating
Warm individual bars in the microwave for 20 seconds or in a 300°F oven for 10 minutes.
