Preheat the oven to 325° F.
In a small bowl or ramekin, whisk together the flax meal and warm water. Let sit for about 5 to 10 minutes.
In a medium to large-sized mixing bowl add the almond flour, cornmeal (if using), salt, baking powder, and nutritional yeast. Whisk or stir well to combine ingredients.
In a separate mixing bowl, whisk together the agave, coconut oil, milk, and flax mixture (if the flax mixture needs to set longer you can use this time to first line your muffin tray).
Combine the wet with the dry ingredients by stirring with a large spoon. Next, stir in the diced jalepeño.
In a lined muffin tray, distribute a 1/4 cup of muffin batter into 8 to 9 muffin cups. I use a 2 oz portion scoop. If desired, top each muffin with a jalepeño slice.
Place the cornbread muffins into your preheated oven and bake for 40 minutes, rotating the muffin tray after the first 20 minutes to ensure even baking. Once baked, allow to cool for approximately 10 minutes before enjoying.
