Topping (option: cut topping in half*)
1/2 c. sugar
1/2 c. butter, melted
1 tsp. cinnamon
Preheat oven to 350F.
In a medium-large bowl, sift together all dry ingredients. Add wet ingredients and stir until combined, but still a bit lumpy. Don’t overmix. Scoop batter into muffin tins that have sprayed with cooking spray. Using a large ice cream scoop, I got 8 medium-large muffins out of this batter; I think you could get 10-12 muffins by distributing the batter a little less generously. Bake for 20-25 minutes, or until they just start to turn a bit golden at the edges.
For the topping, mix sugar and cinnamon in a small bowl. Place melted butter in another small bowl. Dip the warm muffins in melted butter (you can dip just the top, but it’s even tastier to dip the whole muffin!), then dip/roll the muffin in cinnamon sugar.
