10tablespoonscold Butterset aside 2 tablespoons for topping
1/4cupbrown sugar
1/2cupQuick Cooking Oats
Instructions
Preheat the oven to 375 degrees. Spray a 13x9 or baking dish with cooking spray, or line a jelly roll pan with parchment paper.
Prepare the filling
In a large saucepan, combine the chunks of berries, sugar, lemon juice, corn starch, and water. Stir to combine. Bring to a gentle boil over medium-high heat.
Once it starts to boil, reduce the heat to medium and simmer, stirring occasionally, until the liquid turns into a thick syrup (about 6-8 minutes). Use a potato masher to smash up some of the strawberry chunks. Remove the pan from the heat and set it aside.
For the Crust/Crumble
Using a food processor, hand mixer (or your hands), mix together the flour. sugar, egg, baking powder, salt, and vanilla. Slowly add 1/2 cup cold (8 tablespoons) butter, mixing until combined. You want it to press together like a damp sand. Set aside in a small bowl 1 1/2 cups of the mixture for the topping.
Pour the remaining mixture into the baking dish packing it firmly.
Add the reserved topping mixture back into the food processor, along with the brown sugar, oats, and the additional 2 tablespoons of cold butter. Mix until crumbly
Spread the strawberry filling over the crust and sprinkle the topping over the filling.
Bake for 40 minutes the filling will be bubbly and the crust will be golden.
Allow cooling for 1-2 hours to set up before slicing.

Notes
Make sure your butter is extremely cold. I cut mine into small pieces and place them in a small bowl in the freezer to keep it really chilled.
If your strawberries are a little more tart. You can add some extra sugar to sweeten them up. Just add 1 tablespoon at a time until desired sweetness.
You can use frozen strawberries but omit the water and let them simmer a bit longer to remove any extra water.
If you don't have a food processor You can use a large mixing bowl and a pastry cutter to mix the buttery crust and crumble mixture, but it will take you much longer to do it by hand.
