Preheat the oven to 375 degrees. In a large mixer, mix both sugars with butter and oil. Throughout the mixing process, scrape the sides of the bowl as necessary with a spatula.
Add eggs and beat well. Then add the rest of the ingredients, except the second 1/2 cup of sugar listed, and beat well.
Using a cookie scoop (or a spoon), drop by tablespoonful onto a cookie sheet lined with parchment paper.
Pour 1/2 cup of sugar into a small bowl. Dip the bottom of a glass into some of the remaining cookie dough in the mixing bowl to get the bottom of the glass a little bit sticky and oily - this helps the sugar stick to the glass. Dip the glass into the bowl of sugar and press each cookie flat. You can dip the glass back into the dough mixture to add a bit more oil if and when you need to. Our recipe makes a lot of cookies, so you'll do this step multiple times!
Bake at 375 degrees for 12-14 minutes or until the edges are a light golden brown. Best when completely cooled.
Optional: Mix some colored sprinkles with the sugar in step 4 for a festive look! Our cookies truly are best when completely cooled, so resist the temptation until that point!
