In a small sauce pan, heat half and half and chocolate chips over medium heat until chocolate melts.
Pour melted chocolate mixture into a blender and add remaining ingredients. Blend until smooth
Spray a small cast iron or non stick skillet (5-6 inches) with cooking spray or wipe with oil on a paper towel.
To test if the pan is at the right temperature, place a tablespoon of batter in the middle, if it cooks completely in 20 seconds the pan is ready. Adjust the heat up or down if it cooks faster or slower.
Respray pan if needed. Pour ¼ cup of batter into pan and swirl until completely coated. Cook for 20-30 seconds until crepe looks cooked and edges just begin to brown, flip, cook for another 20 seconds to brown the other side.
Remove from pan place on a plate and cover with a clean towel to keep warm until finished cooking the remaining batter.
