* To cook this on a gas grill, you want the burner under the skillet to be off. With a three burner gas grill, preheat grill to 350°F by adjusting the left and right burners and leaving the middle burner off. Once grill reaches a consistent temperature, place skillet on grill to cook. Avoid opening the grill cover as you lose a lot of heat.
* If you don't have an oven-safe skillet, you can use a baking pan instead.
* If you want to make this truly gluten-free use gluten-free flour (such as
Cup4Cup Multipurpose Flour) in place of the all-purpose flour and gluten-free almond flour (such as recommend
Bob's Red Mill Super-Fine Natural Almond Flour).
* Cake can be frozen. Cool to room temperature and wrap before freezing.
