In a medium-sized mixing bowl, combine the almond flour with the egg, baking powder, baking soda, and a pinch of sea salt. Mix briefly to make a batter.
Brush a non-stick pan with a bit of butter over medium heat, and add dollops of the English muffin batter, making sure to leave enough room to expand.
Cook for about 30 seconds on each side or until the muffin has puffed and a toothpick inserted into the center comes out clean.
Transfer the muffins onto a plate and let them cool for a few minutes.
Slice crosswise and toast in a dry pan. Serve hot with your preferred toppings.
