To make the jars: Whichever cookie jar recipe you’re making, combine the first 3 ingredients (flour, baking soda, salt). Now it’s time to layer the ingredients in 32-ounce mason jars. I suggest layering the dry ingredients into the jars in a thoughtful way so each layer stands out. Dark (cocoa powder), light (granulated sugar), dark (brown sugar), light (flour + baking soda + salt), dark (chocolate chips), then the peppermint bark or M&Ms. Use a spoon to layer or, if you’re particular like I am, use a funnel so the layers are extra neat. Seal the lids, decorate with ribbon, and gift with the free printable tags.

To bake the cookies: In a large bowl using a handheld mixer or stand mixer fitted with a paddle attachment, beat the butter, egg, and vanilla extract together on high speed until combined. Don’t worry if the egg isn’t fully combining with the butter; it’ll all come together with the dry ingredients. Add all of the jar ingredients and mix on low speed until combined. Cookie dough does NOT require chilling. Drop by rounded Tablespoonfuls onto parchment paper or silicone baking mat lined baking sheets, about 3 inches apart. Bake in a 350°F (177°C) oven for about 10 minutes until the edges are set. Each recipe yields about 2 dozen cookies. Cookies stay fresh in an airtight container at room temperature for up to 1 week or in the freezer for up to 3 months. Cookie dough balls freeze well for up to 3 months. Here’s how to freeze cookie dough.
