Preheat the oven to 350 degrees F and line a baking sheet with parchment paper.
Combine all the dry ingredients into a large bowl and whisk to combine.
Add the wet ingredients (oil, syrup, pumpkin, egg, vanilla) and beat to combine.
Scoop the mixture onto the parchment paper and smooth them with the back of a metal spoon or flatten with a fork. Bake in the center of a warm oven for 12 - 15 minutes, until the cookies are golden brown.
