Gluten-Free M&M's Soft Sugar Cookies
These soft sugar cookies are lightly flavored with lemon. If you don't like lemon with chocolate, omit the lemon extract.
At the time of this writing, some bags of M&M's carry a "may contain wheat" warning, especially flavored varieties. If you aren't comfortable using M&M's, other chocolate candies work well.
