You’re Going To Love This Keto Yellow Cake:

And here’s why:

  • As easy to make as a boxed cake mix
  • Comes out perfect every time
  • Double or triple the recipe for a layered cake or a big sheet cake
  • Tastes like the golden butter cake you’re already familiar with
  • Perfect for birthday cakes
  • Thick chocolate fudge frosting tops it off
  • Gluten free
  • Only 1.4 net carbs per piece



Making Your Own Keto Golden Butter Cake

I know people hate the word, but, this keto yellow cake is so moist! All of that butter guarantees this cake isn’t eggy or dry, promise. Best of all, there aren’t any special products in this keto butter cake recipe. You only need 6 basic low carb ingredients and one bowl to whip up this one up. Use a hand mixer or stand mixer to prepare the batter, bake in a prepared cake pan (see next section for cake pan sizing), and cool until you’re ready to frost. 


What Size Cake Pan Should Be Used In This Keto Yellow Cake Recipe

I’ve made this keto yellow cake into a sheet cake with a 9×13 pan, cupcakes, and as a layer cake using an 8″ or 9″ round pan. You could even make it in a bundt pan and use it for pound cake. 

Here are suggested bake times for various cake pan sizes:

  • 8″ round– 25 to 30 minutes
  • 9″ round– 20 to 25 minutes
  • 12 cup muffin/cupcake- 12 to 15 minutes
  • 8×8 square– 25 to 30 minutes
  • 9×13 sheet– 15 to 20 minutes
  • bundt– 25 to 30 minutes

Because this cake doesn’t rise very much since it is gluten free, the height of your cake will be dependent on the size of the pan you use. Also keep in mind that every oven bakes slightly differently so check for doneness (golden top, toothpick poke comes clean) at the shorter minute mark.



Can This Low Carb Cake Be Doubled For a Layer Cake

Absolutely, in fact, I recommend it! If you’re using this recipe as a birthday cake, double or triple the recipe and evenly divide the batter between two or three 9″ round cake pans for an ultra special sugar free birthday cake!


What Does The Sugar Free Chocolate Fudge Frosting Taste Like

Oh, the frosting…we haven’t even talked about the frosting yet! Remember the canned fudge frosting? Yeah, this sugar free chocolate fudge frosting tastes just like that. It’s thick, rich, and extremely chocolatey! And just like the cake, the ingredients are few and basic. I suggest mixing up the frosting while the cake is baking so that it is ready to spread on the cooled cake.

Ingredients and Substitutions For Your Keto Yellow Cake:

Want to know if you can substitute flours? Not sure which sweetener to use? Here’s a list of substitutions that should help answer those questions:

  • Almond Flour– do not substitute coconut flour with almond flour. Unfortunately, coconut flour is not a congruent baking substitute for almond flour. Coconut flour has different properties and is not measured cup for cup like almond flour. If your almond flour baked goods have a nutty taste, I suggest trying a different brand like Anthony’s or Bob’s Red Mill (or Costco brand if you’re a member). Also, make sure your almond flour is super fine for the best crumb.
  • Sweeteners– powdered and granular sweetener can be used in the cake portion of the recipe. Personally, I think powdered sweetener yields the best results but when using (most) powdered sweetener, you must remember to check the ratios on the bag and adjust accordingly. For example, 1 cup of granular sweetener is typically 1/2 cup powdered. Also, some brands vary in measurements (like Pyure) so be sure to check the ratio on your product’s bag. And always use powdered sweetener  in frostings so you don’t have a gritty frosting.

the cake and frosting tasted great but i think a 9x13 is too big. my cake was rather flat. and despite putting butt all over the pan and sides, it stuck horribly. the whole thing crumbled to pieces trying to get it out. I'll try again with 8x8 or muffins.

Hi- I'm sorry you had trouble with the cake being overcooked and sticking. That should not happen in any pan that is well greased, including a 9x13. Keep in mind that gluten free cakes do not rise much so a single batch of batter will not reach the top of the cake pan, that is normal. I would suggest seeing if your oven is properly calibrated because if not, they will not disburse heat evenly and cause overcooking (I just had this issue in a new house/oven and burning baked goods).

In this keto yellow cake chocolate frosting recipe, is the amount for baking powder 15-FIFTEEN teaspoons or is it 1 1/2 -one and a half teaspoons? Thanks!

Hi, it is 1 and 1/2 teaspoons. :)

What size pan did you use (in the picture)? 8" round? And if so, does this recipe make one or two?

This recipe makes 1 layer cake. You can use any size pan you’d like but it is not enough to split into two layers. You’d need to double it for a layer cake.

question : do we need two different types of sweetner for this recipe (it looks like they're both powdered) or can i just use the same for the frosting and cake? thank you!

you can use the same for both! :)

I found your recipe when looking for a low carb yellow cake to make pineapple upside down cake. Would your cake recipe work?

Well, theoretically yes, but pineapple is not keto friendly and there isn't really a substitute to achieve that flavor.
