Mix together the chia seeds and 4 tbsp water and let sit for a few minutes to form a chia egg.
Preheat the oven to 350 °F. Line 9 muffin cups with paper muffin liners. Set aside.
Combine the dry ingredients in a large mixing bowl. Add the wet ingredients, the chia egg, and the chocolate chips, and mix for about a minute on low speed.
Divide the batter evenly between the muffin cups. Place the pan in the oven and bake for 15 minutes.
Remove the pan from the oven and allow to cool for a few minutes. Store the muffins in an airtight container in the freezer for later consumption or serve immediately.
