Notes
In the recipe I added 1/2 a cup of chocolate chips. I also tried it with more and found the problem to be that all of the chocolate chips sank to the bottom of the muffins. If you want more chocolate chips then I would recommend sprinkling them on top of the batter after it is scooped. But if you like the bottom of your muffin to be full of chocolate chips I found out it’s pretty delicious when warmed up.The calories shown are based on the recipe making 12 muffins, with 1 serving being 1 muffin.
