In a medium-sized bowl, stir together lupini flour, baking soda, xanthan gum, and salt. Set aside.
In a large mixing bowl, combine together oil, Lakanto golden monk fruit sweetener, eggs, vanilla extract, peanut butter extract (optional), and no sugar added peanut butter. With your mixer, mix for 2-3 minutes to allow for the sugar substitute to dissolve. Note: skipping this step will result in a grainy cookie.
Blend in the lupin flour mixture until a dough forms and ingredients are completely mixed together. Cover your bowl and allow the dough to rest for 10 minutes. You can also place the dough in the refrigerator and bake up to 36 hours later.
In the meantime, with the oven rack in the middle position, heat your oven to 325 degrees.
Line two baking sheets with parchment paper and portion dough onto the cookie sheet so they are spaced 2-3 inches apart. You should be using about 1 ½ tablespoons of dough at a time. The cookies will flatten in the oven as they bake.
Bake cookies one sheet at a time for 8-10 minutes or until edges are golden brown but the centers are still soft. The cookies will appear to be not yet baked. Remove the cookie sheet from the oven and let the cookies cool on the sheet for 30 minutes. Tip: bang the cookie sheet on the counter a few times if you want a more cracked look on top.
Once cookies are completely cooled, store in a tightly sealed container on the countertop for up to four days or in the freezer for up to three months.
