Gluten Free Peanut Butter Cake

Peanut Butter Cake

Enough already Lisa. (Don’t worry I’m just talking to myself for a bit).

Surely people are over the whole sweet potato and peanut butter combination by now?

But it tastes so good (also me but the good one).

Peanut Butter Cake

Remember this ice cream from last summer or this slice that we had to hide before the kids ate it all. Can’t we do just one more

Ok. But this has to be the last one.

Of course (fingers crossed behind back).

So this Gluten Free Peanut Butter Cake is for all the PB lovers out there. There’s lot of peanut butter in this recipe. There’s also a lot of sweet potato. But don’t be scared off, it does taste pretty good.

The Gluten Free Peanut Butter Cake is quite dense yet still has a light texture. I like to blend my wet ingredients together (with the exception of the eggs) before adding them to make sure there is no evidence  of the sweet potato. It also helps to incorporate the peanut butter and make for a smooth cake texture.

Once all the dry ingredients have been added you may find that the mixture is really thick. Like so thick that the whisk can’t stir it. It’s ok, it’s suppose to be thick. Just swap the whisk for a spoon and get stirring until everything is well combined. You may end up with guns of steal like Arnie. Work and cake; win win!!!

I have topped my Gluten Free Peanut Butter Cake with Peanut Butter Frosting, the same one I used in this PB’n’J Layer Cake). Depending the the type of coconut cream and peanut butter used you may need to add coconut oil to the frosting to keep it firm. If your cream is on the runnier side add 2-3 Tabelspoons of coconut oil. With or without the extra coconut oil, the frosting will need a few hours in the fridge to thicken before using.

You could also add a touch of Chocolate to the Peanut Butter Cake by using this Chocolate Frosting, this Ganache or something a bit different this Caramel sauce
