Keto Peanut Butter Frosting
Peanut butter frosting is very popular in my keto home bakery.
The peanut butter frosting is light, fluffy and so good. Mixing together smooth peanut butter, butter and Swerve confectioner’s sugar, we have the best keto chocolate cake with a keto peanut butter frosting you could have.
The key to mixing the peanut butter is to warm it up a bit in the microwave (not hot, just warm) and adding to buttercream. This will yield a very fluffy, sugar-free peanut butter frosting.
I like using a smooth peanut butter that does not have added sugar, such as Maranatha, but any sugar free brand will work. If you use a natural brand that has to be stirred, make sure it’s incorporated and warm up a bit to soften.
Use Swerve Confectioner’s Sweetener
You can read here why I love this brand of powdered erythritol for sugar free and keto baking. You can use other sweeteners such as Lakanto, which also contains monk fruit. It’s a matter of choice.
Keto Celebration Cakes
The bakery now offers six inch, triple layer celebration cakes. Chocolate with peanut butter frosting is one of the popular flavors. Keep the cake as a naked cake. No need to frost sides. You will be putting plenty of frosting on three layers. You can also make this as double layer 8 inch cake.
How to make a chocolate cake grain free and gluten free
Keto Chocolate Cake is my speciality. I think I’ve developed just the right mix of everything. When you have a bakery and bake a recipe over and over and over, you tweak and perfect. We tweaked this one a lot, because we had to find the right cocoa powder.
Almond Flour – This is the key component in a keto friendly cake. Use blanched.
Coconut Flour – Adds moisture to the texture, and absorbs liquid more easily.
Eggs – Eggs act as a binder and give body to the cake. I use six large eggs for this purpose.
Avocado oil – This is my preferred fat for the cake. Oil is better for most of my cake recipes. The cake will rise more and not harden in the refrigerator.
Baking Powder – Baking Soda – These leaven cake.
Salt – I use a fine sea salt.
Cacao – We use Better Body Foods Cacao, because not only is it healthy, it has a great depth of flavor.
Coffee – The coffee is important. Don’t substitute with espresso powder. If you must substitute, use a liquid such as almond milk, but you won’t have that rich taste. I use Counter Culture 46 coffee beans and brew an espresso shot. I suggest a good, strong coffee if you don’t do espresso.
Sour Cream – Use full fat sour cream and avocado oil. You can use unsalted butter instead of avocado oil with equal results. Avocado oil does help the cake rise a little more, but both yield a great cake.
Xanthan Gum – Some people write me about the xanthan gum. Can you leave it out? Yes, you can. I include it, as it keeps the cake together. If you’re going to be doing a lot of keto baking, it’s worth the investment.
Piping bags – Hands down, these are my favorite disposable piping bags. They have a texture and are easy to hold. I use these daily in the bakery with my favorite 1M tip, which uses this coupler.

- Add the vanilla paste. If I want a serious vanilla taste, I'll add more vanilla paste.
