Brownie in a Cup ~ Wipe the outside of the cup with rubbing alcohol. Use an oil based Sharpie paint marker, then write the instructions onto the cup. Let the Sharpie dry completely for 24 hours. Place your cup in a cold oven, then bake at 450 degrees for 30 minutes. Crack your oven door and let the cup cool down with the oven to prevent cracking. This would be great as a gift, add the dry ingredients and wrap.
Love Sharpie Mug Done May 22nd 2015- Finally tried the sharpie mug! 16 mugs done with black and white stylized trees so that guests can tell which cup is theirs. Used Oil based Sharpie and dried and then baked. The kind of sharpie is really important.
