Pancake mix (or homemade if you prefer)
Green and blue food coloring
1 large bowl
2 small bowls
You make the pancake mix as you would normally, divide up the mix in the two small bowls, add blue food coloring to one and green to the other, mix well.
Heat your pan to medium heat and spray with Pam.
Here are pictures of how I did it:
If you prefer prefect circles, trim the sides.
Tip: make sure you pour quickly so you don't keep the pancakes on the pan too long or it will brown too much.
