Cake:

4 tbsp all purpose flour
3 tsp granulated white sugar
1/4 tsp baking powder
1/8 tsp cinnamon
1/16 tsp nutmeg
3 tbsp fat free milk
1/2 tbsp vegetable oil

Cinnamon swirl

1 1/2 tbsp brown sugar
1/8 tsp cinnamon
1/2 tbsp butter

Frosting (makes enough for 2)

1/2 tbsp butter
1 tbsp cream cheese
2 - 2 1/2 tbsp powdered sugar

Note: For this recipe, I deliberately kept it small since there's so much sugar and calories in the cinnamon swirl and frosting. But if you wanted to, you could make a giant one by doing 1 1/2 times the recipe and cook it in a really wide mug or ramekin (that holds at least 12 oz), which will make it come out looking like a giant cinnamon roll (like the one in the close-up photos and background).
