Next time I would make the crust as a crumble top but it was good and took about half an hour and was super easy
I poured frozen blueberries in a bowl and defrosted them in the microwave. Added cinnamon, about a cup of sugar and a ¼ cup of brown sugar, a tablespoon of flour and a teaspoon or so of vanilla and mixed it all in a bowl. For the crust I took a box of old cookies that were kind of stale (we had shortbread Girl Scout cookies) and smashed them up. I added melted butter and pressed the mixture into a cake pan. I poured the blueberry mixture into the crust. I took 2 pats of butter cut into 4ths and placed it around the top of the blueberry mixture. Baked for 20 min at 350 and it was quite tasty. Serve with whipped cream or vanilla ice cream.
as you can see it was well received :)
