Crispy exteriors and soft + chewy interiors with M&Ms and Chocolate Chips -- these are the ultimate holiday cookie!
IN THE MASON JAR: combine the flour, baking soda and salt in the bottom of a 1-quart mason jar. Tap the jar several times firmly to get the flour mixture in one layer. Press it down as much as possible. Next, add in the brown sugar and pack down as much as possible. Next, add in the white sugar and again pack that down. Add in the M&Ms and chocolate chips. Press down firmly. Seal the mason jar, add a ribbon with a miniature whisk (if desired), and attach the free printable recipe attachment (or the following directions)
