Ingredients

Crust and Crumble Topping:
1½ cups butter, melted and slightly cooled
1½ cups brown sugar, lightly packed
2 cups all-purpose flour
2 cups old-fashioned oats
1 teaspoon kosher salt
1 teaspoon baking soda
1 teaspoon cinnamon
1½ teaspoons vanilla extract

Apple Filling:
3½ cups apples, peeled and diced (Granny Smith and Gala recommended)
1 teaspoon allspice
1 teaspoon lemon juice
2 tablespoons all-purpose flour

Caramel Sauce:
1 (10.8 oz) package soft caramels (such as Werther’s)
3 tablespoons heavy cream
½ teaspoon vanilla extract

Directions

1. Preheat oven to 350°F. Line a 9×13-inch baking pan with parchment paper and set aside.

2. In a large bowl, combine melted butter, brown sugar, flour, oats, salt, baking soda, cinnamon, and vanilla. Stir until fully mixed.

3. Press half of this oat mixture evenly into the bottom of the prepared pan to form the crust. Set the remaining half aside for the crumble topping.

4. In a separate medium bowl, toss the peeled and diced apples with lemon juice, allspice, and flour until evenly coated. Spread the apple mixture evenly over the crust.

5. In a saucepan over medium-low heat, melt the caramels with the heavy cream, stirring frequently until smooth. Remove from heat and stir in vanilla. Let cool slightly.

6. Drizzle the caramel sauce evenly over the apple layer.

7. Crumble the reserved oat mixture over the top of the caramel-covered apples.

8. Bake for 25–30 minutes, or until the top is lightly browned and the apples are tender.

9. Remove from the oven and allow the bars to cool for about 30 minutes before slicing.

10. Serve warm, chilled, or topped with a scoop of vanilla ice cream.

Freezer: Freeze cut bars in a single layer, then transfer to a freezer-safe container or bag. Freeze for up to 2 months. Thaw in the fridge before serving.

Reheating: Warm individual bars in the microwave for 20–30 seconds, or enjoy chilled straight from the fridge.

FAQs

What kind of apples work best for these bars?

Granny Smith and Gala apples provide the perfect balance of tartness and sweetness. You can also use Honeycrisp or Fuji.

Can I use store-bought caramel sauce?

Yes, you can substitute ¾ cup of thick store-bought caramel sauce if you’re short on time.

Do I have to peel the apples?

Peeling is recommended for the best texture, but you can leave the skin on if preferred.

Can I use quick oats instead of old-fashioned oats?

Old-fashioned oats are best for structure and texture. Quick oats may result in a softer crumble.

How do I know when the bars are done?

The edges should be lightly browned and the apple layer should bubble slightly around the edges.

Can I make these ahead of time?

Yes, they taste even better the next day once the layers have set. Just store them in the fridge.

Can I use apple pie filling instead of fresh apples?

You can, but it will be much sweeter. Reduce the added sugar or omit the caramel for balance.

How do I cut the bars neatly?

Allow them to cool completely before slicing. For the cleanest cuts, refrigerate for at least 1 hour and use a sharp knife.

Are these bars good for potlucks or parties?

Yes, they transport well and are easy to serve as individual portions.

Can I skip the caramel?

You can, but the caramel adds a rich, sweet layer that elevates the whole dessert.
