Ingredients

  • 1 Tbls coconut flour we use this
  • 1 Tbls flaxseed meal we use this
  • 1/4 tsp baking powder
  • 1 large egg
  • 2 Tbls coconut oil or Butter
  • 1 Tbls Allulose You can also use Erythritol
  • 1/2 tsp Ground Cinnamon
  • 10 drops liquid monkfruit You can also use liquid Sucralose or stevia. For liquid Sucralose, you only need a few drops

Instructions

  • Put butter or coconut oil in a microwave safe mug or ramekin and melt for 15-20 seconds
  • Before adding in egg, make sure you allow the melted butter or coconut oil to cool a bit
  • Add coconut flour, flaxseed meal, baking powder, and egg and mix until batter is well combined then let sit for about 1 minute.  Batter should become very thick.
  • In a separate bowl, create cinnamon sugar by combining Allulose and cinnamon
  • Pour cinnamon sugar onto top of mug and swirl it in.  Don't completely mix.
  • Microwave for 90 second to have a gooey center and 2 minutes for a firm muffin.
  • To increase the fat, put 1/2 tablespoon butter on top to serve.

Notes

Tips for using  Coconut Oil instead of Butter,
  • Adjust for Richness: Coconut oil is 100% fat, whereas butter contains about 16% water. You may find the texture slightly more "oily," so consider adding an extra teaspoon of coconut flour if the batter looks too thin.
  • Salt Balance: Since you lose the salt naturally found in salted butter, add a tiny pinch of sea salt to the mix to enhance the flavors of the cinnamon and allulose.
  • Flavor Shift: Expect a subtle tropical note that replaces the traditional dairy richness—this pairs beautifully with the flaxseed for a nuttier finish.
