Combine the dry ingredients in a stainless steel bowl. Combine the liquid ingredients in a separate bowl using a whisk. Pour the liquid ingredients into the dry ingredients and whisk together. Allow to rest for 30 minutes before cooking.
When ready to cook stir in the jalapeno and cheddar cheese. Cook on a lightly oiled griddle or low sided pan. When the first side has cooked to a golden brown, flip and cook second side. Serve immediately.
