Keto Shortbread Cookies

Updated: May 2

I've made keto shortbread before and have used it in many of my recipes. But I was always limited in recipes I could make because it was a higher carb recipe using mostly coconut flour. I learned through the years of experimenting with making keto recipe that I can use a lot less coconut flour and more whey protein in the recipes. So I got working on a lower carb shortbread that was crispy outside and soft and melt in your mouth inside.

It is a super simple recipe with only a few ingredients. You can make any shape short bread shape out of this dough. The trick is to not refrigerate the dough for too long and to shape it how you would like it before you chill it. I think the easiest way is to slice it once chilled. The dough is soft and crumbly when it is not refrigerated so I think it will be a pain to roll and cut out shapes.

The flour I use is a combination of coconut flour and unflavored whey protein isolate. The whey protein gives a fluffy interior to the cookie. I use Isopure which is 0 carbs per scoop, you can probably use a concentrate but that will add carbs to the cookie. People have found that you can replace the whey protein with egg white protein powder in my cookie recipes but that will probably result in a crispier cookie. I always suggest weighing everything in this recipe it is really hard to get a correct weight with measuring spoons.

The sweetener I used was a powdered which makes making the dough much easier because it dissolves easier. You can use any Erythritol blend or bocha sweet. Allulose makes baked goods brown very fast and stay soft, so I don't recommend allulose for much cookie making.

The best way to cook the shortbread to make sure to chill completely solid then bake for 6-10 minutes depending on your oven. If your oven runs hot, keep an eye on it after 5 minutes. You just want them starting to get golden around the edges but not on top. And no matter what do not eat them until they are completely cooled. They don't crisp up until fully room temperature. You may even think they are cooled but I tried them early before and the are not crispy until FULLY cooled!
