Combining the dry ingredients. Whisk together the flour and flaxseed meal to incorporate them together and aerate. Add the baking powder, salt, cardamom, and cinnamon. Whisk them all together. Make a well in the center of the dry ingredients.
Combining the wet ingredients. Whisk together the buttermilk, almond extract, and eggs. Pour the liquid into the dry ingredients. Stir with a rubber spatula until the batter is combined. Add the melted butter and stir until the pancake batter is entirely combined.
Making the pancakes. Preheat the oven to 250°. Put an oven-safe plate in there.
Set a cast-iron skillet over medium-high heat. Grease the pan liberally with oil or butter. Pour the pancake batter into the buttered pan, about ¼ cup at a time. When bubbles have started to form and pop on the top of pancake, flip it. Cook for about 1 minute more, then put the crisp pancake in the oven to keep it warm.
Continue this until you have cooked all the pancakes.
