Preheat oven to 350 degrees. Grease muffin tins, or place little muffin papers in each.

(Optional but preferred: Put the lemon zest and sugar into a food processor and blend until zest is all blended in with the sugar. This is good to impart a more lemony flavor. )

In a large bowl, cream coconut oil and coconut sugar. Add eggs one at a time, until creamy and combined.

Place the egg whites separately in a medium deep bowl.

If you don’t have buttermilk, then you can easily make this substitute, that works just as well:

You’ll need 1/2 cup of buttermilk, so in a liquid measuring glass, pour in 1/2 tablespoon of vinegar. Then pour in the milk till it is filled up to 1/2 cup. Let sit for a few minutes, until curdled.

In a separate medium bowl, mix the flours, baking powder, baking soda, salt, poppy-seeds, and lemon zest. (if you already blended the lemon zest in with the sugar like I earlier suggested, then obviously, you won’t be putting it into this bowl)

Dump the flour into the sugar/oil mixture. Alternate this with pouring in the buttermilk, and lemon juice, and then vanilla, until everything is combined.

With a high-speed handmixer, whip the egg white until tall peaks form, and it is light and fluffy.

Carefully fold in the egg white into the batter until completely incorporated. Spoon evenly into the 12 muffin tins.

Bake in oven for about 25 minutes, or until golden brown.
