Kentucky Butter Cake Recipe

I have tried and directed a lot of Crumbl Cookie Flavors. Trust me. I make weekly review videos and have tried every single flavor, every single week since I started.

Kentucky Butter Cake was one that I have been dying to try but haven’t had the chance, until this last week. Kentucky Butter Cake is one that everyone RAVES about, I have gotten the request for a copycat recipe over and over and over again.

Well, folks, I finally got my hands on one, tasted it and promptly melted into my seat. The cookie is something so unique and that buttery glaze on top makes the whole cookie.

Now you can make 12 in your own kitchen AND put on as much glaze as you’d like. Boom Shaka-laka.

Ingredients needed to make Kentucky Butter Cake Cookies

Cookie Base

  • Salted Butter– I always use salted butter when baking because I really try to make your life easier and not have to purchase two kinds of butters. You’ll see below though, for the glaze, I suggest using unsalted. I’ll explain why in the glaze section, but for the cookies, use salted butter!
  • Brown Sugar– This recipe uses far more brown sugar than granulated sugar. That was one of the first things I noticed when I tasted this cookie- it had a really strong brown sugar flavor that I loved!
  • Granulated Sugar
  • Eggs
  • Vanilla Extract
  • All Purpose Flour
  • Yellow Cake Mix– Yes. Yellow cake mix. I used the brand Duncan Hines when testing this recipe. This is actually an ingredient labeled in Crumbl’s Nutrition facts, so YES, yellow cake mix definitely went into my copycat version.
  • Corn Starch
  • Baking Soda
  • Salt

Buttery Glaze

  • Unsalted Butter– Okay, hear me out. I have made the glaze with both unsalted and salted butter. Because this is a buttery glaze and it doesn’t have a ton of powdered sugar in it, the glaze made with the salted butter comes out a little salty. I actually really like it with the salty kick, but it doesn’t match Crumbl’s flavor exactly. Crumbl’s glaze is all sweet, with that buttery vanilla flavor. So can you make it with salted? Yes, it will be delish. If you want an exact Crumbl Replica, I’d suggest using unsalted butter.
  • Powdered Sugar
  • Butter Vanilla Emulsion– You’ll want the brand Lorann’s. I purchased mine from Hobby Lobby, you can also purchase it on amazon or directly from Lorann’s website. You can use plain vanilla if you’d like, it will taste a bit different but still delicious.

How to Make Kentucky Butter Cake Cookies at home

Making these cookies at home is not much different than making any other cookie. You’ll first combine the butter and sugars, next goes in the eggs and vanilla. Make sure to scrape the sides of the bowl so everything is mixed together evenly.

Next goes in the dry ingredients- in this cookie that is flour, yellow cake mix, cornstarch, baking soda and salt. Mix all of the ingredients together until well combined. The cookie dough will be very soft.

Scoop a generous 1/3 of a cup of dough out for each cookie. You should end up with exactly 12 cookies. Arrange 6 on each pan. Roll the dough into a ball with your hands and then flatten the cookie dough just slightly. They will spread some, so keep the cookie dough about 2 inches tall.

Bake at 375° for 9-11 minutes. The cookies will spread and the edges will turn golden brown. That’s when you’ll know its time to take them out of the oven.

As soon as you take the cookies out of the oven, make the buttery glaze. To make the glaze, you’ll whisk together the butter and powdered sugar in a small sauce pan on the stove top over medium heat. Whisk, whisk whisk, until the powdered sugar and melted butter combine into a creamy glaze. Whisk in the butter vanilla emulsion and then use a pastry brush to brush the warm glaze onto the warm cookies.

Allow the cookies to cool for 10 minutes, dust with powdered sugar if desired and then serve.

Can I make a smaller batch of cookies?

Yes! Just half the ingredients and make 6 cookies instead of 12!

How to store leftover cookies

Store in an airtight container. They will last for about 3 days at room temperature, for 1 week in the fridge or up to 3 months in the freezer! I like to use either zip top bags or air tight large Tupperware containers.

How to reheat cookies

Place the cookies in a 350° oven for 3-4 minutes and you’ll have fresh out of the oven cookies again, just like when they first came out!

  • Allow the glaze topped cookies to cool for 10 minutes before dusting with powedered sugar.

Notes

* I suggest using unsalted butter in the glaze because otherwise it comes out more salty than Crumbl’s glaze. It is still delicious when using salted butter, it just isn’t exactly like Crumbl’s which is why I suggest the unsalted butter. If you just have salted, it will be okay! I actually like it with that extra salty kick. 
**If you don’t have or don’t want to purchase the butter vanilla emulsion, you can substitute vanilla extract.

    My daughter’s favorite cookie is the Kentucky Butter Cake Cookie from Crumbl. I made these the other night. She said they were “spot on” and coming from her, that was a huge compliment. Her friend said they were better than Crumbl. These cookies are so good!

    I just finished making these and the result was perfect. This is an excellent, concise recipe. The only thing I wish I could change is the calorie count – oh well !
