Peach Upside-Down Cake on the Grill
Baked on a charcoal grill for a little smoky flavor, our peach upside-down cake is made with fresh peaches caramelized to perfection.
In large bowl, stir together granulated sugar, milk, oil, vanilla and egg until sugar is completely dissolved. Beat in flour, baking powder and salt until well blended.
Pour batter over peaches in pan, covering peaches completely and smoothing batter with spatula or back of spoon.
Fill 8-inch square foil pan halfway with water. Place in bottom of grill; arrange hot coals around pan. Place grill rack on grill. Place cake pan on rack directly over pan of water. This will allow cake to cook evenly over indirect heat.
Cover grill, leaving vents open. Bake cake 40 minutes or until toothpick inserted in center comes out clean. Cool completely on cooling rack, about 45 minutes.
Run thin knife around edges of pan to loosen cake. Place serving plate upside down over pan; turn plate and pan over. Remove pan.
