Vegan Gluten Free Sweet Potato Chocolate Chip Cake (Low Fodmap)

This moist, delicious sweet potato chocolate chip cake is easy to make and is totally vegan, gluten free and suitable for the low fodmap diet.

I’m going to straight up admit that gluten free baking is not really my area of expertise. I don’t really know any coeliacs/gluten intolerant people so it isn’t something I’ve ever needed to do on the regular.

Recently however, Damian has been giving the low Fodmap diet a try (it is SUCH a ballache of a diet but needs must…). The elimination phase requires you to cut out basically everything that contains gluten (and just about everything else as well it feels like!), so I’ve come up with a few gluten free and low fodmap friendly bakes so he can still have a little bit of joy in his diet.

This sweet potato chocolate chip cake is both vegan and gluten free, as well as being suitable for the low fodmap diet. It uses a base of ground oats and almonds instead of flour which makes it soft and moist. It is bound with cooked mashed sweet potato, maple syrup, almond milk and full fat tinned coconut milk.

There is no extra fat added to this cake other than the fat from the coconut milk so don’t swap this out for another kind of milk or it might not work as well.

This is not an overly sweet cake – it is sweetened just with maple syrup; so a healthy dose of chocolate chips provide a bit of extra sweetness. (And the more chocolate chips the better in my opinion!).

This is a great cake for snacking on and because it is a bit more nutritious than regular cake you don’t need to feel guilty about having two slices!

How To Make Vegan And Gluten Free Sweet Potato Chocolate Chip Cake:

(For ingredients and full instructions see the recipe card below)

*For the best results make sure that you follow the recipe closely. As always, I highly recommend using the gram measurements (with a digital scale), rather than the cup conversions. Cup measurements are simply not accurate enough for baking and I cannot guarantee the best results if you use them.*

Start by making your sweet potato mash – Take one medium-large sweet potato and prick it a couple of times with a sharp knife. Microwave for around 10 minutes, turning it over halfway through, until it is soft. You can also bake it if you prefer; but it takes longer.

Allow to cool a little then peel off the skin, place the flesh in a bowl and mash. Measure out 120g/1/2 cup of the mash for the cake and reserve any left over for another use. (I give it to my dog, he loves it.).

(If you are measuring the potato by weight, not cups (which I always recommend!) then there is no need to mash it as you will be blending it in a minute anyway.).

(You only need one sweet potato – two are pictured as I nicked this photo from my vegan sweet potato bread with pecan streusel post).

Tip your oat flour/ground oats (see below for instructions on how to make it) into a large bowl along with ground almonds, baking powder and salt and mix it well with a balloon whisk so no lumps remain.

Place your cooked sweet potato in a blender along with tinned full fat coconut milk (no substitutions!), almond milk (or another thin plant milk, or just water is fine), maple syrup (or you can use agave) and vanilla extract. Blend until smooth.

Pour the wet ingredients into the dry and mix well, the batter should be very thick. Stir in the chocolate chips.

Scrape the batter into a 23cm/9inch square greased and lined cake tin and spread it level. Bake until a skewer inserted into the centre comes out clean or with a couple of moist crumbs but no wet batter.

Leave the cake to cool in the tin before turning it out and slicing into squares. It MUST be completely cold before you cut it otherwise the texture will be too wet.

How Long Will It Keep?:

I find that this cake doesn’t keep particularly well – about 3-4 days max in an airtight container. Left for too long, particularly if the weather is warm, you may find that it goes mouldy.

How To Make Oat Flour:

You can purchase ready ground oat flour; but it is really simple to make your own. You just need to blitz rolled oats in a blender until they are very finely ground; it takes all of about 30 seconds.

I just weigh out the 215g of oats that I need for the recipe, grind them up in the blender, tip them out into a bowl then blitz up the wet ingredients as per the recipe (no need to clean the blender first).
