Almond flour, derived from ground almonds, offers a delightful texture and nutritional boost to these classic treats. It's naturally gluten-free, high in protein and healthy fats, making it an excellent alternative for those looking to reduce their carb intake or follow a gluten-free diet. Plus, it adds a wonderful nutty flavor that complements the sweet and tangy cookie flavors perfectly.

Start by preheating your oven to 350°F (175°C) and lining a baking sheet with parchment paper. In a large bowl, combine the almond flour, sugar, and salt. Whisk until well incorporated.

Next, add the softened butter, egg, and vanilla extract. Mix well until a sticky dough forms. If you'd like to add some chocolate chips, fold them in now for an extra treat. Divide the dough into six equal portions.

Now comes the fun part! Add a dot of food coloring to each portion of dough, mixing well to create vibrant shades of red, orange, yellow, green, blue, and purple. If the dough becomes too sticky, refrigerate it for a few minutes to firm up.

Roll each colored dough portion into a 6-inch log. Once all colors are logged, place them side by side on a sheet of wax paper and roll gently to create one slab of rainbow dough. Wrap the rainbow slab tightly in plastic wrap and refrigerate for about an hour to firm up.

Bake for 10-12 minutes or until the edges are golden brown. Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
