This is a family favorite keto cake recipe that my mom is allowing me to share with you beautiful low-carb people. You’re welcome, and thank you, Mom!

“Are you sure this is keto? Where is the coconut flour taste!? This is too smooth to be keto!”

This was everyone’s reaction when we first tried this delicious cake, no joke!

Making This Keto Blueberry Chocolate Cake Better

There is a secret ingredient in this cake that takes it above and beyond! That ingredient is ricotta cheese. Coconut flour is good, and is definitely a keto must-have, but for this cake, ricotta was the game-changer that we used. Ricotta made this cake so creamy and velvety!

I know, I know… when you think of ricotta cheese, you think of lasagna and stuffed shells and other Italian dishes, but trust me – ricotta belongs in cake, too!

There’s also another ingredient in this cake that makes it so moist and cakey, and that is olive oil! Typically, you’d put vegetable oil in a cake, but we reached for olive oil instead — it is mostly monounsaturated fat and carries a little of its own flavor — and it worked flawlessly!

How To Make Keto Blueberry Chocolate Cake:

The photos run in order — the cake first, then the frosting and the blueberry topping. The recipe card below carries the full Directions for all three.

Eight numbered photos of the cake: ricotta in a lined bowl, melted butter, butter and cream cheese beaten together, the mixture whipped smooth, the dry cocoa mixture, the finished chocolate batter, the batter spread in a lined pan, and the baked cake

The second set covers the frosting and the blueberry topping.

Six numbered photos of the finishing: cream cheese and cocoa in a mixer bowl, cream poured in, the beaten chocolate frosting, blueberries beside sweetener packets, the berries warming in a pan, and the frosted cake piled with them

Blueberry Topping

The yummy blueberry topping is good on its own, but when it sits on top of this decadent cake, it is magnificent! The warm blueberries and the juice that seeps into the cake are just to die for! Of course, you can use whatever fruit you would like! Strawberries would be another delicious option!

Where you see an em dash: one of the ingredients in this recipe does not publish a figure for that row, so we cannot add one up honestly. We would rather show you nothing there than a zero we cannot stand behind.

About these numbers: We are home cooks, not certified nutritionists. Nutrition is shared as a courtesy and calculated with free online nutrition calculators — we compare a few to get as close as we can — so please treat it as a helpful estimate rather than a guarantee. The brands you buy, any swaps you make, and how generously you portion the recipe will all move these numbers.
