    This cake is so easy and delicious, it has been a lifesaver to me struggling to feel like I can’t have a keto treat so I made two and cream frosted between 😍

  5. This is not a keto recipe. It contains honey. Honey is not used in keto recipes due to its incredibly high sugar content.

    Six thumbs up from my two children and me! This was so easy and fast to make. Best of all was that we had all of the ingredients. Only change i made was adding cinnamon, nutmeg, and cloves to give it a spice cake twist with fall right around the corner. It went beautifully with the cream cheese frosting, also crazy easy to make. Thank you!

    I made this few times. I like how easy and quick I can eat! When I don’t have time to bake. I just adjusted amount of oil bit less( used coconuts oil) and add coconuts milk instead.some with coco powder. I used coconuts coco cream topping instead of cream cheese topping.

    1. This was great! I made a 1/2 serve and used maple syrup, coconut oil and cacao i also substituted 1tbs of the almond Flour with psyllium husk and i served it with coconut cream and blueberries. It was so moist snd yummy! Thank you
