Step 1

Preheat oven to 350°F.

Step 2

If desired, peel peaches. Thinly slice. If using canned peaches, drain well. Toss peaches with brown sugar, granulated sugar, and cornstarch. Set aside.

Step 3

Combine Bisquick mix, milk, cinnamon, and vanilla in a medium mixing bowl. Pour into an ungreased 9x9" baking dish. Melt butter and stir into Bisquick mixture until just combined.

Step 4

Layer peaches on top of Bisquick mixture (it will rise around the peaches as it bakes).

Step 5

Bake for 50-60 minutes or until a toothpick inserted into the center comes out clean. Serve warm with vanilla ice cream.
