2 cups flour
1 Tbsp baking powder
½ tsp baking soda
½ tsp salt
1 tsp cinnamon
2 large eggs
1 cup plain yogurt (I used low-fat plain yogurt)
2/3 cup packed brown sugar
4 to 8 tbsp oil ( I used 4 tbsp oil)
1 tsp vanilla
Topping:
1/2 stick butter, melted
1/4 cup sugar
½ tsp cinnamon
Position oven rack in the middle position and preheat oven to 400 degrees. Line a standard muffin pan with paper cups. Whisk flour, baking powder, baking soda, salt and cinnamon in a large bowl. In a separate bowl, whisk together eggs, yogurt, sugar, oil, and vanilla. Add flour mixture and mix with light strokes until the dry ingredients are just moistened. Don't over mix; batter should not be smooth. Divide batter among the muffin cups and bake until a toothpick inserted in one or two of the muffins come out clean, 12-15 minutes. While the muffins are baking, melt 1/2 stick butter and place in a bowl just large enough to hold a muffin. Combine sugar and cinnamon in a small, shallow bowl. As soon as the muffins are done, dip them one at a time in the melted butter and then roll in the sugar mixture. Set on a rack to cool.
