blueberry crumb cakes

i was going to have brunch with a friend of mine this sunday and i was trying to think of something pretty quick and easy, but still fancy enough to be brunch worthy. i was hoping muffins or coffee cake would do the trick, however i wanted to try something new. i ended going through my family cookbook and found this recipe for crumb cakes. i added the blueberries to the recipe and i think it's the perfect addition. but let's be honest, blueberries make just about anything better.

batter:
1 cup flour
2/3 cup sugar
1/4 t. baking powder
1/4 t. baking soda
1/8 t. salt
1/8 t. cinnamon
1/3 cup buttermilk
2 T. butter, melted
1 egg
1 t. vanilla
2/3 c. blueberries

topping:
1/2 c. flour
1/3 c. brown sugar
2 t. cinnamon
4 T. cold butter, cut into pieces
(cut with pastry cutter or two knives until crumbly)

preaheat oven to 375°, grease 12-cup muffin tin. combine dry ingredients till well mixed. whisk wet ingredients till combined. add wet ingredients to dry ingredents and mix with fork until just combined. add blueberries and mix unti l just combined. divide batter between 12 cups (i actually only got 10 cups out of mine, and i used a cookie scoop to divvy up the batter). top with topping and pat down. bake for 12 - 14 minutes. cool 5 minutes and transfer to wire racks.
