Preheat oven to 350° and prepare muffin pan wells with paper liners.
In a large bowl whisk together buckwheat flour, tapioca flour, coconut flour cocoa powder, salt, and cinnamon.
In a mixing bowl combine honey, avocado oil, and eggs. Using either a stand mixer or hand mixer beat until frothy, about 3 minutes.
Add in nondairy milk and vanilla extract; mix to blend.
Add flour mixture to wet ingredients and beat for another 2 minutes.
Allow batter to rest for 5 minutes to let the flour absorb the liquids.
Mix in baking soda, and then fold in frozen strawberries.
Spoon batter into prepared muffin pan.
Bake 30 to 40 minutes, until an inserted toothpick comes out clean.
Allow muffins to cool in pan for 5 minutes then transfer to a wire rack to continue cooling.
Store in an airtight container at room temperature for up to 2 days or frozen for 3 months.
