Spray 4 mini loaf pans (5x3") with non stick spray, then line with parchment paper. I prefer Baker's Joy for this recipe.
Preheat oven to 325 degrees.
Cream butter and sugar in a mixing bowl till fluffy. Beat in eggs, vanilla, and sour cream.
Stir together flour, baking powder, salt, and cinnamon in a small bowl. Add to wet ingredients and stir lightly.
Toss the two tablespoons of flour with the cinnamon chips. to coat them. (It helps prevent them from sinking.) Add them to the batter and stir till combined.
Divide batter into 4 mini loaf pans. Combine topping ingredients and sprinkle over the batter in each of the pans.
Bake at 325° for 45-50 minutes or until toothpick inserted in the center comes out clean. Cool for 5-10 minutes before removing from pans onto cooling racks.
Notes
-The cinnamon chips tend to stick to the pan, so use parchment paper for best results.
