Whisk egg, sugar and brown sugar in a medium bowl until smooth. (if using maple syrup add it here.)
1 Large Egg, 1/3 Cup Sugar , 1/3 Cup Light Brown Sugar
Whisk in apple butter, cider, sour cream and oil.
1/2 Cup Apple Butter, 1/3 Cup Sour Cream, 1/4 Cup Canola Oil
Make a well in the dry ingredients; add the wet ingredients and stir with a rubber spatula until just combined.
Scoop the batter into the prepared muffin cups (they’ll be quite full).
Bake the muffins until the tops are golden brown and spring back when touched lightly, 18 to 22 minutes. Sometimes an oven may need up to 25 minutes. Just tap the tops and when they don't sink a little upon touching they are all done.
Let cool in the pan for 5 minutes.
Loosen edges and dip the tops into the melted butter and then the sugar mixture (I like to roll mine all over in butter and sugar but it is more messy)
For the Topping
Melt the butter and set aside. Whisk together the sugars and cinnamon in a large bowl. Set aside
1/4 Cup Butter, 1/4 Cup Sugar, 1/4 Cup Brown Sugar, 1 Tablespoon Ground Cinnamon
