Measure out and prepare all of the ingredients. Preheat oven to 350F.

In a saucepan, add the unsweetened almond milk and butter.

Heat it over medium heat until the butter has just melted.

In a blender, add in the melted butter and almond milk. Then add in the eggs and vanilla extract. Add in all of the dry ingredients: erythritol, almond flour, coconut flour, pea protein, baking powder, and sea salt.

Pulse on a low setting then turn to a medium setting until the batter is smooth.

Line a muffin pan with muffin liners. Brush some melted butter on the inside of the liners.

Fill the muffin liners with the batter equally. Bake in the oven for 20 - 25 minutes or until a toothpick inserted into the muffins comes out clean.

Let cool, serve, and enjoy!
