1 large peach or 2 medium, pitted, peeled (if desired) and thinly sliced
1/4 cup coarse or organic sugar
1/2 teaspoon ground cinnamon
Preheat oven to 350°F. Line 2 regular sized muffin tins with 14 paper muffin liners.
In a large bowl, combine the cake mix, milk, oil and vanilla. Beat the batter until smooth. Stir in the peach slices. Scoop the batter into the prepared muffin tins.
In a small bowl, mix together the cinnamon and sugar. Sprinkle the sugar mixture on top of the batter in each muffin cup. Bake the muffins in the preheated oven for 25 to 35 minutes, or until a tester comes out clean. Let cool completely and enjoy!
