Step 1

Preheat the oven to 350°F. Spray a 12 inch cast iron skillet with Baker’s Joy or a similar nonstick baking spray.

Step 2

Using an electric mixer, beat the butter and 1 cup of sugar until light and fluffy, about 3 to 4 minutes. Add eggs one at a time, then sour cream and vanilla. Mix until smooth.

Step 3

In a medium bowl, sift together flour, baking powder, baking soda, and salt. Slowly add the dry ingredients to the wet ingredients, mixing until combined.

Step 4

In a separate bowl, mix the remaining ½ cup of sugar and cinnamon.

Step 5

Spread half of the batter into the skillet, top with half of the peaches, and sprinkle with half of the sugar-cinnamon mixture. Repeat with remaining batter, peaches, and sugar-cinnamon mixture.
