30 Mug Cakes in 30 Days - Chocolate Chip Muffin - Day 2

I've shared this one with the facebook group already, but it's a favorite of mine so I had to make it again!

Chocolate Chip Muffin

1/4 cup flaxseed meal
1/2 tsp. baking powder
1 Tbs. sweetener (I use xylitol)
dash of vanilla
1 egg
1 tsp. butter, melted
2 Tbs. sugar-free chocolate chips (I use Hershey)

Mix the dry ingredients together until well combined.  Add egg and butter and blend well.  Fill muffin cups (2-3) and bake at 350 degrees for 20 minutes.  Toothpick should come out clean when done.  I like to slice them and top with butter.  So yummy!
