Step 1

Preheat the oven to 375 degrees. Line an 8x8 pan with parchment paper so that it hangs over two sides.

Step 2

Put the gluten free oats, gluten free flour, vegan buttery spread, brown sugar, and salt in a large bowl.

Step 3

Using a pastry cutter or two forks, mix the ingredients together until it resembles large crumbs.

Step 4

Place half of the crumbs in the bottom of the prepared pan. Use your hands to pat it down firmly.

Step 5

Bake the bottom crust at 375 degrees for 15 minutes. Remove from oven.

Step 6

Put the blackberries on top of the crust, and evenly distribute them. Top with the remaining crumble mixture, patting it down lightly.

Step 7

Bake at 375 degrees for 25-50 minutes, until the berries are bubbling and the crumb topping is golden brown.

Step 8

If you plan to slice this into neat bars, be sure to let it cool completely. Otherwise, you can use a spoon to scoop it out and enjoy it while it is warm.
