Yes you can use flaxmeal, it might not taste as good though. I use flaxmeal in the 1 minute muffin.
1/4 cup flax meal or almond flour or coconut flour
1/2 teaspoon baking powder**
1 packet sweetner (I use Truvia)
1 teaspoon cinnamon
1-2 teaspoons butter
Mix the dry ingredients in a large coffe cup. Add egg and butter; mix well. Microwave for 50-seconds to 1-minute. Muffin pops right out.
Top with berries or eat as is.
**Making Baking Powder
•You need baking soda and cream of tartar to make baking powder.
•Mix 2 parts cream of tartar with 1 part baking soda. For example, mix 2 tsp cream of tartar with 1 tsp baking soda.
•Use the amount of baking powder called for by the recipe.
I've been making flax meal - coconut flour pancakes for the past week in P3. I had some sensitivity issues with nuts when I first entered P3, so have stayed with flax and coconut flour. May not taste as good as almond flour, but the pancakes come out great!
