Pre-heat oven to 375 degrees and line two baking sheets with parchment paper.

In a large bowl, combine oil, sugars, egg and vanilla extract. Mix well to combine.

In a separate bowl, sift together flour, xanthan gum (if using), baking soda and salt. Stir to combine and add to the wet ingredients.

Stir the dough until all the dry ingredients are mixed into the wet ingredients. Divide dough in half and transfer each half to a baking sheet. Use your hands to form each piece of dough into a 15"x3" rectangle. Sprinkle 1/4 C of the chocolate chips on each of the dough rectangles and lightly press into the dough. Refrigerate for 20 min.

Bake for 10 min. at 375 degrees. Cool on pans until room temp. and then use a serrated knife or pizza cutter to slice cookies into sticks that are about 1.5 inches wide. Transfer to wire racks to cool completely. Store in an airtight container.
