Blueberry Buckle Coffee Cake

I still have blueberries in my freezer so I went searching for a new recipe to try. I adapted the recipe from Tasty Kitchen (submitted by fcopeland). We enjoyed it.

Blueberry Buckle Coffee Cake

For Cake:
2 c flour
3/4 c sugar
2 1/2 tsp baking powder
3/4 tsp salt
1/4 c shortening
3/4 c milk
1 whole egg
2 c blueberries
For crumb topping:
1/2 c sugar
1/3 c flour
1/4 c butter, softened
1/2 tsp cinnamon
For the glaze:
1/2 c powdered sugar
1/4 tsp vanilla
2 tsp hot water
Preheat oven to 350. Mix the first seven ingredients together then gently stir in the blueberries. (I put mine in frozen) Then pour into a greased glass pie plate. (This is just a little to much batter for a pie plate so two options: put it in a bigger baking dish or bake it with a cookie sheet under it to catch the overflow.)

Mix the crumb topping ingredients together. Crumble it over the top of the cake before putting it in the oven. Bake it for 45-50 min.
To make the glaze just simply stir the ingredients together till sugar dissolves and it is smooth.
Once cake is removed from the oven drizzle with the glaze.
