Confession, my body does not always handle gluten and dairy very well. I have an autoimmune disease which puts my body in fight or flight mode and creates a lot of inflammation. A few years ago I was doing great, I was completely grain free and watched my intake of dairy and sugar. Unfortunately I fell off the band wagon and have yet to get back on. I have been relearning what gluten free, dairy free, and vegan looks like in sweet and savory dishes in order to pass delicious recipes on to you. But don’t worry, if you keep scrolling I give you options on how to make these vegan or opt out of the gluten free or dairy free.

Ingredients for Apple and Plum Crumble Bars

The oat crumble is both the bottom and top layer of these bars. It is….

  • Old fashioned oats
  • Gluten Free Flour- I use King Arthur Baking’s product, its awesome!
  • Almond flour- a little bit of almond flour adds moisture and texture
  • Brown sugar-
  • Cinnamon
  • Plant butter

The apple and plum filling is simple yet so flavorful. And I was so surprised by how well apple and plum paired together. They did not overpower one another.

  • Apples; peeled and diced
  • Plums; peeled and diced
  • Cornstarch- this will thicken the fruity mixture as it bakes
  • Fresh lemon juice
  • Brown sugar
Ingredients for Crumb Bars and the Filling

Time to Construct and Bake!

Once the two mixtures are combined it is easy as 1,2,3, bake! Well, first you need to preheat your oven to 375° F and prepare your 8×8 baking dish with parchment paper and non-stick cooking spray. Then . . .

  1. Press 2/3 of the oat crumble mixture in the bottom of your baking dish
  2. Pour your apple and plum filling on top of that
  3. Sprinkle the remainder of the oat crumble on top

Bake for 40 to 45 minutes or until golden brown and the filling is bubbling. Allow your crumble bars to cool in the pan until they are room temperature. Cut into 9 equal squares and enjoy!

Recipe Substitutions

Vegan Version- To make this dish vegan you can sub out the brown sugar for cane sugar, coconut sugar, or the sweetener of your choice and have no issues.

Gluten Version- If you do not want this to be gluten free or do not have gluten free flour or almond flour, you can use all purpose flour.

Dairy Version- Again, if you do not want this to be dairy free or do not have plant butter, you can use regular unsalted butter.

Ingredients
  

Oat Crumble

  • 1 cup old fashioned oats
  • ¾ cup Gluten Free Flour; I use King Arthur Baking's
  • ¼ cup almond flour
  • ½ cup brown sugar
  • ½ teaspoon cinnamon
  • ½ cup butter (I used plant butter); melted

Apple & Pear Filling

  • 1 cup apples; peeled and diced
  • 1 cup plums; peeled and diced
  • 1 teaspoon cornstarch
  • 1 tablespoon lemon juice; fresh
  • ¼ cup brown sugar

Instructions
 

  • Preheat your oven to 375° F and center the oven rack.
  • Prepare an 8×8 baking dish with parchment paper and non-stick cooking spray.
  • In a medium sized bowl combine the rolled oats, almond flour, brown sugar, cinnamon, and melted butter. Combine with a fork until the butter has evenly saturated the mixture.
  • Place ⅔ of the oat crumble into the bottom of your prepared baking dish. Evenly distribute and press down with the back of a glass or measuring cup. You want the mixture to be compacted so it doesn't crumble and fall apart. Set aside.
  • In another medium sized bowl combine the peeled and diced apples and plums, corn starch, lemon juice, and brown sugar.
  • Top the oat crumble mixture with your fruit mixture. Make sure it is evenly distributed throughout.
  • Crumble the leftover ⅓ oat crumble mixture on top of the fruit mixture. It doesn't have to be perfect.
  • Bake for 40-45 minutes until golden brown.
  • Allow to cool in the pan until room temperature.
