Hemp hearts are the center and most nutrient-dense part of the hemp seed. These muffins pack an extra punch of protein from the hemp seeds sprinkled on top, the greek yogurt inside and the eggs. They are a perfect, filling AND portable breakfast or snack that won't leave you wanting more. You can customize them with "mix-ins" of your choice as well but I prefer mine plain with some Siggi's yogurt or almond butter on top.
