Peanut Butter Potato Cakes

Low calorie at only 100 calories per cake. These are sweet and full of good nutrients. Made with sweet potatoes, flour and oats with just a little sweetness and flavouring added, these Potato Cakes are super easy to make, you can be stuffing them into your mouth within the hour and because they’re so small and minimal ingredients they’re great for kids.

There is a lemon version of these cakes here and a banana version here as well. It’s a very adaptable recipe.

Tip – If you use Crunchy Peanut Butter instead of smooth you will get some crunchy peanuts throughout the mix which give a wonderful extra crunch to the texture (as you can see in the picture below). Alternatively, you could mash some almonds, pecans or another nut of your choice and put this into the mix. 

You could also add something even sweeter in such as chocolate chips and turn them into a mix of peanut butter and chocolate chop potato cakes OR skip the potatoes and use the mixture as a base for other recipes such as blueberry muffins.

I recently made a second batch of these and included some chia seed and other mixed seeds and they turned out great.

If you enjoy this recipe you should try the Peanut Butter Protein Balls, another wonderful recipe for peanut butter lovers out there. Or, how about something a little bigger, the Chocolate & Gingerbread Silk Cake would be perfect.
