Combine almond flour, whey protein isolate, Swerve/Lakanto, baking powder, and salt together in a large bowl. Add the heavy cream, eggs, and corn extract. Stir until well combine. Fold in the cheddar cheese, scallions, and jalapeno.
Evenly divide the batter into the prepared muffin tin pan. Option to place additional jalapeno slices and green onions on top, just be sure to press to adhere to the top of the muffins. Bake in preheated oven for 24-27 minutes, or until the centers have set. Enjoy!
