Whether you're out on a family car camping trip or out backpacking, this backcountry grapefruit pound cake makes a delicious campfire treat. All the ingredients together weigh approximately 17oz so this recipe is more of a luxury for backpacking. However, this grapefruit pound cake contains mostly dry ingredients and the wet ingredients don't need to be refrigerated. These factors make it an awesome treat to bring along on your next car camping trip. Cooking the dough in the grapefruit ensures that the pound cake cooks more evenly and it really enhances the overall sweet, tangy, flavor. We hope you enjoy just as much as we do!
