Apple Pie Crumble Bars {Guest Post}
This sweet and crunchy apple pie crumble bar recipe will leave you wanting another piece! It’s everything you expect from a slice of pie but in a convenient bar; a buttery crust, flavorful apple pie filling, and a sweet and crunchy crumb topping.

Hi Baked by Rachel readers! I’m Lauren, the owner, baker and recipe developer behind Keep It Sweet Desserts, an online bakery specializing in artisanal mail-order treats. It is perfect timing for a guest post on Rachel’s blog, since later this fall I’ll be buried in butter, sugar and chocolate.
I’m really excited to be a part of An Apple a Day again this year! Last year I posted one of my favorite fall recipes, so I knew it would be hard to top that this time around. You know what, though, I think I at least came close!
While I love apple pie, I like the ease and convenience of a bar-like-treat even more. These Apple Pie Crumble Bars are made with three components: a buttery crust, flavorful apple pie filling, and sweet and crunchy crumb topping. My husband offered to help me in the kitchen the day I made them so I put him to work on the apple filling and the rest was a breeze!
You know what else I loved about these? You could serve them as-is at a casual pot-luck or party with many desserts, or dress them up with some vanilla ice cream and salted caramel sauce. Oh, and they are great for baking ahead of time. You can just wrap them up when cooled and freeze them for up to a few weeks. This definitely amps up the convenience factor!
Apple Pie Crumble Bars
Ingredients
Crust:
- 12 Tbsp unsalted butter softened
- 6 Tbsp granulated sugar
- 1 1/2 C all purpose flour
- 1/4 tsp salt
Filling:
- 3 Tbsp unsalted butter softened
- 1/4 C light brown sugar
- 6 medium-sized apples
- 1/2 Tbsp ground cinnamon
- 1 pinch nutmeg
- 1/2 C water
Topping:
- 2 C rolled oats
- 1 C all purpose flour
- 3/4 C light brown sugar
- 1/2 Tbsp ground cinnamon
- 1/4 tsp baking soda
- 1/4 tsp salt
- 12 Tbsp unsalted butter cold, cubed
Instructions
- Pre-heat oven to 375°F degrees and line a 9x13 pan with parchment paper.
- Prepare crust; in the large bowl of an electric mixer, beat butter and sugar on medium-high speed until light and fluffy. Reduce speed to low and slowly add flour and salt just until combined. Scrape the sides of the bowl with a spatula. Press dough onto bottom of prepared baking pan so that bottom is completely covered. Bake for 20 minutes or until crust is lightly golden. Remove from oven and set aside until filling and topping are ready to use.
- While crust is baking, prepare apple pie filling; Melt butter with brown sugar in skillet(s) over low-medium heat (see note). Add apples and cook over medium-high heat, stirring occasionally, until apples are softened (about 10 minutes). Stir cinnamon and nutmeg into apple mixture and continue to cook until the apples are caramelized and liquid has evaporated, about 10 more minutes; if apples begin to stick to skillet(s) during this time, add a little bit of water to prevent burning.
- Set filling aside to cool and prepare topping.
- To make crumb topping, combine rolled oats, flour, brown sugar, cinnamon, baking soda and salt in a large bowl.
- Use two knives to cut the cold butter into oatmeal mixture; you can then use your hands to combine the mixture until the topping is in clumps about the size of a pea.
- Place apple filling over crust and then press crumb topping down lightly over apple layer so that it is completely covered.
- Bake for about 30 minutes in center of oven or until topping is lightly browned and set.
- Store bars at room temperature up to three days.
Notes
These bars can be made up to one month in advance. When bars are baked and cooled, wrap tightly in foil and store in freezer until day of serving.
