mini sweet potato flour “flat” cake recipes (made with just 6 ingredients)

by purelytwins

Mini sweet potato flour cake recipes made from 6 ingredients.

Looks like sweet potato flour sounds good to many of you and are curious about trying it out yourself! Yay! Let us know if you experiment with it.

Like we said, we have been enjoying baking with this new flour alternative.

Sweet potato flour really creates such an unique taste and texture to recipes.

Gluten-free cakes made from sweet potato flour.

We think you will love the recipe we have for you today. We have both a vegan version and a non-vegan version of this cake recipe. But keep in mind these are not your average cakes. These flat cakes as we are calling them, are very dense and wet/moist like (we know not the most flattering way to describe something but it is true).

Again the sweet potato flour is the key ingredient.

Before we start getting questions and emails about substitutions for the sweet potato flour – we will say there is really none. BUT, of course you could use any gluten free flour blend or any flour of your liking but it will result in different outcome. Not saying that is bad. This goes for all recipes (not just ours).

This cake is supposed to be a sweet potato flour cake.

A little background about this recipe. When we started to create this recipe we wanted a cake that was easy to make, few ingredients, and attempt it with no baking soda or baking powder to see what happens. Plus bake them in mini tart pans because we think they are cute. Outcome: a sweet socca like cake.

We kept going back and forth actually on what to call this recipe. As they are very thin almost like a pancake flatbread texture.

We thought about calling it thin sweet potato flour cakes but were unsure if using ‘thin’ would sound appetizing. So we are calling it a flat cake –  sweet potato mini  flat cake since we did not think flatbread was good either to call it (oh the dilemma in finding a name for this recipe).

sweet potato mini cake

You could look at this recipe as a sweet flatbread recipe if you wanted to. Almost like socca. Either way it is different and tasty.

We first made the recipe using eggs (which does come out the best over the vegan version), but then decided to make the same recipe using a flax gel for the egg substitute. It worked. Well for the most part it did, more on that down below.

We found both cakes:

  • to taste amazing
  • have a dense moist texture
  • almost ‘socca’ pancake like (for those that are new to our love of socca, it is our go-to flatbread made from garbanzo beans, a simple rich dense flatbread)
  • few ingredients
  • easy to make
  • great with a plain or with a frosting

Like we mentioned yesterday in our few trials, our final result kept getting a green hue to it. So we omitted the leavening agent (baking soda and baking powder) and just relied on apple cider vinegar to lift these mini cakes some (again it worked best in the egg version).

our vegan flaxmeal cake

First we made our sweet potato flour cake with an egg. Loved it. But knew people would want an egg free version. So, we already went ahead and tried it with a flax gel instead of the egg. It worked…well for the most part.

Since we did not use any leavening agent besides the apple cider vinegar to keep the recipe simple, the vegan version did not rise that much. But to us it still taste good, just a little more dense and moist. **update: we tried the vegan version with 1/4 tsp baking powder, did not really rise much still, so we will keep trying but wanted to go again and share that we made if you would like to experiment.

our egg version of cake

Note these are not a light and fluffy cake. More along the lines of rich and dense-wet cakes. Still addicting in our opinion. What can we say we are weird and like unique textures.

Plus they are made with just 6 ingredients! Not bad for a sweet cake.


mini sweet potato flour “flat” cake recipes (made with just 6 ingredients)

Mini sweet potato flour flat cakes. Two recipes. Gluten-free. Egg-free option.

  • Prep Time: 5 minutes
  • Cook Time: 18 minutes
  • Total Time: 23 minutes
  • Yield: makes 2 mini cakes or 4 cupcake size 1x


  • 3 tablespoons sweet potato flour
  • 1 egg or 1 flax gel
  • 1015 drops liquid stevia or 1-2 teaspoons of sugar of choice (not necessary to add if you do not want a real sweet cake)
  • 1/2 tablespoon coconut oil
  • 45 tablespoons coconut milk
  • 1 teaspoon apple cider vinegar
  • **for vegan version you could add in some baking powder, plus we found it worked a little better with 4 tablespoons sweet potato flour.
  • ***another note: you could make buttermilk if desired instead of doing the ACV and coconut milk separate


  1. Pre-heat oven to 350 degrees.
  2. In a large bowl place your sweet potato flour, stevia, coconut oil and egg or flax gel (let sit for 10 minutes). Stir together.
  3. Next add in your apple cider vinegar and coconut milk. Stir till combined.
  4. Batter will be a little thick.
  5. Grab your mini tart pans.
  6. *could use a regular cupcake pan instead
  7. Place in oven and let bake for about 18-20 minutes. ** Vegan version took a little bit longer to bake more like 25 minutes.

Top your mini cakes with some coconut butter frosting!

PurelyTwins Quick Frosting:

  • 2 tablespoons coconut butter
  • 1 tablespoon coconut milk
  • 1 tablespoon coconut nectar (or any liquid sweetener of choice)

*note: if you do not like the flavor of coconut you could add in some vanilla or another flavoring to frosting

We also went ahead and baked the egg version in a cupcake baking pan since we know that not everyone has a mini tart pan. And it worked as flat mini cupcakes, made about 4 mini cupcakes.

This time we used coconut milk mixed with chia seeds to make another quick topping. Did about 1 tbsp chia seeds to 3 tbsp milk. Add in sweetener if desired.

As you can tell we used no cupcake liners. Just lightly oiled the cupcake pan before baking the cakes in it. **note: if you make them as vegan version they still come out really dense and wet/gooey.

We went a step further and tried it with a chia gel as egg replacement.

Unfortunately using chia gel as the egg did not work out as nicely as the flaxmeal did. Not sure why but these were even more ‘not’ cooked gooey moist texture –> sorry not sure how else to describe it.

But we are going to keep trying to make a recipe using chia seeds with the sweet potato flour and keep it vegan. We will report back when we have it.

Ellen @ Wannabe Health Nut September 14, 2012 - 1:30 pm

You had me sold at “sweet potato + 6 ingredients”! Always looking for new ways to cook with it…haven’t tried the flour yet, though!

EatenLittle September 14, 2012 - 3:12 pm

To save money, I’ve had great luck substituting steamed, smashed baked potatoes for any recipe that calls for sweet potato flour plus any liquid. Since the sweet potato absorbs liquid while steaming/boiling, you can use this in place of any sweet potato flour recipe that calls for flour *and* a liquid. If cooking and mashing your own sweet potatoes from the farmer’s market when in season, this becomes a great farm–>table strategy, too! 🙂

great tip!

Amber @ExSoyCise September 17, 2012 - 10:25 am

You girls are just too cute! Those sweet potato cakes sound devine! I’m new to the sweet potato flour, going to have to try asap!

Danielle December 19, 2012 - 6:25 am

Hi girls, I am sensitive to coconut! I know aweful right lol! Is there a substitute I can use for coconut oil, coconut butter, or coconut milk in your recipies. How about Ghee o earth balance for butter substitutes? And for the milk will any other non dairy milk work?

purelytwins December 19, 2012 - 11:24 am

Danielle in terms of our baked recipes yes you can use ghee and any non-dairy milk would work. For our raw desserts it is hard to replace coconut oil in those, you could use melted cacao butter. Hope this helps.

I would love to make these, but I can’t have vinegar! Can you recommend a replacement?

purelytwins October 1, 2013 - 7:26 pm

Anna you can just omit the vinegar part.

Lila July 6, 2014 - 11:43 pm

I played with sweet potato flour and made ginger spice scones with cranberries and a chocolate muffin turned out great!

Lissa April 24, 2016 - 10:37 am

I purchased a different brand of sweet potato flour. My flour was the consistency of cornstarch. I followed this recipe and my batter was very thin. I added a pinch of salt and pure vanilla extract and made crepes instead. They were good!

This note is mostly to warn people that the batter might not thicken at all.
