This keto sugar cookie cake is a deliciously tender giant almond flour cookie with sugar free sprinkles and frosting. It’s the best of both worlds for keto dessert lovers.
Is it a cookie or is it a cake? Does it even matter? The distinction won’t make a difference once you taste this delicious sugar cookie cake.
This is my birthday week. Yes, I said week, because we all deserve to enjoy a full seven days of festivities on our birthdays. Of course, with three kids, a new puppy, and a job, I probably won’t.
I will let my children and husband fete me on the actual day, and then I will get my nose back to the grindstone. Because that is was I do.
But rest assured that I will eat keto birthday cake. And plenty of it!
Cookie cake is the best of both worlds
Have you ever had trouble deciding between cake and cookies for dessert? We’ve all been there – it’s a universal problem.
But with a keto cookie cake, you don’t have to make that tough decision. I admit, it’s really just a big cookie baked in a cake pan, but it scratches that itch for both.
It’s also easier to make than a traditional birthday cake. Don’t get me wrong, I adore a classic treat like Keto Devil’s Food Cake or even something fancier like Keto Italian Cream Cake.
Given that I am the one making my own birthday cake every year, sometimes I like to go simple and effortless. We often make the Keto Skillet Cookie, because my whole family loves it.
But this year, we’re going funfetti style with sugar-free sprinkles! And some of ChocZero’s white chocolate chips. It is my birthday, after all.
How to make Keto Cookie Cake
Have I sold you yet on making a keto sugar cookie cake? Whether or not it’s your birthday, I highly recommend it.
- Butter: Salted or unsalted, it’s up to you.
- Granular sweetener: I recommend an erythritol based sweetener, as allulose or Bocha Sweet may make the cookie very soft and cake-y.
- Eggs: One whole egg plus one egg yolk will help make your cookie cake chewier, with a richer cookie flavor.
- Vanilla extract
- Blanched almond flour: The finer your flour, the better the results! The best substitutions for almond flour are other nut or seed flours, such as sunflower seed flour. Coconut flour does not well in this recipe.
- Baking powder
- Sugar free white chocolate chips: These are optional but tasty! Feel free to use chocolate chips instead, if you prefer.
- Sugar free sprinkles: There are several great choices out there now. But you can always make your sugar-free sprinkles too.
- A mixer: You can use a hand mixer or a large stand mixer for this recipe.
- 9 inch springform pan: Springform pans are the ideal choice for cookie cakes. You can remove the pan sides for easier cutting and presentation.
- If you don’t have one, you can bake this in a pie dish or ovenproof skillet.
- Parchment paper: Lay a circle of parchment on the bottom of your pan for easier release.
Tips for the best keto cookie cake
Room temperature ingredients: I cannot stress how important it is to use properly softened butter and room temperature eggs. Cold butter won’t cream properly and cold eggs will make your butter clump up.
Fold the sprinkles in by hand: They can bleed color if they are mixed in too vigorously. So add them after the rest of the ingredients are well mixed.
Don’t over-bake it: Take the cookie cake out when the sides are golden brown but the top is still puffy and soft. It won’t seem completely baked through but will continue to bake in the pan.
Be mindful that baking times are only rough guidelines. Much depends on your oven and what pan you use. Keep in mind that glass and ceramic pans tend to take longer to bake.
Let it cool completely: As tempting as it might be to dig in right away, the cookie cake will be too soft and fragile when it’s warm. Plus your frosting will melt if you try to add it to a warm cookie!
Storage instructions: Cookie cakes can dry out easily if left uncovered. Be sure to wrap it up tightly in foil or plastic. It will keep on the counter for up to 4 days, or in the fridge for a week.
Decorating a keto cookie cake
Some sugar-free frosting turns this giant keto sugar cookie into a festive treat. Perfect for a birthday celebration.
The frosting in this recipe is a cross between cream cheese frosting and buttercream. I like this combination because I don’t need copious amounts of powdered sweetener to give it structure.
It makes just enough frosting to pipe pretty rosettes around the edge of your cookie cake. If you’d prefer chocolate try a half batch of my Keto Chocolate Frosting.
