Banana Cream Cheese Muffins

We seem to have a lot of bananas that get overly ripe around here. Mainly because A has love hate relationship with them. Some weeks he eats as many as possible and others he won't touch them. That only means one thing, I MUST bake with them! These muffins are from How To:Simplify.

For the muffin batter:
1 1/2 cups AP flour
1 tsp baking soda
1 tsp baking powder
1/2 tsp salt
3 bananas (mashed)
3/4 cup white sugar
1 egg
1/3 cup butter (melted)
1 tbsp vanilla extract

For the filling:
4 ounces cream cheese (softened)
1/4 cup sugar
1 egg

For the topping:
1/3 cup light brown sugar
1/4 cup AP flour
1/2 tsp ground cinnamon
1 tbsp butter (melted)

Heat oven to 375. In a bowl combine flour, baking powder, baking soda and salt. Whisk together. In a separate bowl beat together the mashed bananas, egg, vanilla and melted butter. Combine the flour mixture and the banana mixture until just moist. Spoon half of the batter into muffin cups. In a bowl combine cream cheese, sugar and egg. Spoon into muffin cups over the batter. Top the muffins with the remaining batter. In another bowl mix together the brown sugar, flour, cinnamon and butter. Crumble over each muffin. Bake for 18 to 20 minutes.
