In a large bowl combine the softened butter, brown sugar, and granulated sugar. Add the egg and combine.
Add the vanilla extract, baking powder, baking soda, and salt and combine.
Add the Einkorn flour and combine. Stir in the chocolate chips.
Drop 2 tablespoons of dough for each cookie on a baking sheet. Flatten the cookies slightly. Bake at 350°F for 8 minutes. Remove when the cookies are only just slightly starting to turn brown at the edges for gooey cookies.
Notes
Softening Butter: If you have not softened the butter ahead of time, place it in a microwaveable bowl and microwave at 20% power for 30 seconds, flip the butter over and repeat as needed until soft, but not super soft or melty.Chilling the Dough: This recipe does not require you to chill the dough. If you do want to chill the dough, you can. Chilling the dough helps the flour to "hydrate" and absorb more of the wet ingredients. The flavors will meld, like a lasagna that is better the next day. I recommend you shape the dough into balls for cookies before chilling. It will make portioning the cookies later easier.Mixing the Dough: You can make these cookies with a stand mixer, a hand mixer, or even just by hand, which I've done plenty of times. If you're wondering if you can make drop cookies by hand, see my Experiment with Mixing Cookie Dough by Hand.
