Supplies
10 in. round or spring-form pan, parchment paper, oil or cooking spray
Ingredients
- 3/4 c rolled oats
- 1 c flour
- 1/2 c brown sugar (lightly packed)
- 1/4 tsp ground cinnamon
- 1/2 tsp baking soda
- 1/4 tsp salt
- 1/2 c unsalted butter, melted
Crisp Top Layer
- 1 c rolled oats
- 3/4 c flour
- 1/2 c brown sugar
- 1/4 tsp cinnamon
- 1/4 tsp salt
- 1/2 c unsalted butter, melted
- 6.5 c fresh blackberries
- 1/3 c granulated sugar
- 4.5 T cornstarch
- ⅛-¼ tsp salt
Instructions
Line the base of the spring-form or round pan with a circle of parchment paper and oil the sides with a neutral oil or cooking spray. (Note: the finished dessert will be about 1-1.5 in height)
Pre-heat the oven to 350F/175C
Melt 1/2 c of butter
Mix together the oats, flour, brown sugar, cinnamon, baking soda and salt for the base layer.
Work in the butter until the dry mixture thoroughly incorporates all the butter and the mixture is a uniformly darker color. This can be done in a stand mixer if available.
Pour into the prepared pan and press down into an even layer.
Bake for about 10 minutes, then set aside to cool or at least 5 minutes.
While the base is baking cook the blackberry filling and crisp topping
Put the blackberries, sugar, cornstarch, and salt into a pan and cook on the stove on medium-high heat. Stir constantly until it comes to a boil.
Turn the heat down and stir regularly (so the filling doesn't stick to the bottom of the pan) until the berry filling thickens. The cooking process takes about 7-10 minutes total.
Take pan off the heat and set aside.
Mix up the topping in the same way as the base and set aside
Once the base layer is cooked and has cooled for at least 5 minutes, spread the cooked berries in an even layer on the base, then dot the top crisp mixture on top fairly evenly, but it's fine if there are gaps where the berry mixtures shows through.
Bake for 35-50 minutes until the top crisp starts to brown.
Cool on the counter for 30 minutes then in the refrigerator until set (about 1 1/2-2 hours total of cooling time).
Enjoy!
