Preheat your oven to 350 degrees.
In a medium bowl, whisk your egg until bubbles begin to form, about one minute.
Add in the other ingredients and stir to combine. The batter will be very thick.
Grease an 8 inch cast iron skillet with butter. Pour in the batter and bake for 18 minutes or until the edges begin to pull away from the side of the pan and a toothpick in the center comes out with crumbs and not liquid batter. Be careful not to over bake.
Serve with Breyers Gelato Indulgences.
