In a microwave safe dish pour in blueberries and add stick of butter. Put microwave on defrost and microwave for 6 minutes. After micro beeps stir and microwave at half power 2 minutes at a time until blueberries are defrosted and butter is melted.
In a mixing bowl mix sugar and flour.
Add evaporated milk. Stir until well mixed. Add a little cinnamon just until there is a LIGHT SPECKLE in the mixture.
Add Almond extract.
In a 9x12 dish (I used glass) spray non-stick cooking spray. (It's important that you evenly coat the pan and that you dont miss a spot becuase it will make cleaning the dish easier.).
Pour blueberry and butter mixture into your baking dish.
Sporatically pour sugar mixture over blueberry mixture. You dont want to much "dough" in one spot so be careful.
