Preheat your oven to 400°F. Line a 12-cup muffin pan and set aside. For the topping: Mix the ingredients together until crumbly. Set aside. For the filling: Mix all ingredients together and set aside. For the batter: Whisk the melted butter, milk, and eggs together in a large bowl. In a separate bowl, whisk together the dry ingredients, including the cinnamon chips. Add the dry mixture to the wet mixture, stirring just until combined. Divide half the batter evenly among the muffin cups. Place ~2 teaspoons of the filling onto each muffin, then top with the remaining batter. Sprinkle with topping and press it in lightly. Bake for 20 to 25 minutes, or until golden brown. Remove them from the oven, and wait 5 minutes before transferring them from the pan to a rack to cool.
