Grain-free egg-free blueberry streusel cake.

by purelytwins

Blueberry muffins are probably one of our favorites. We won’t turn down a pumpkin muffin but for some reason we adore blueberry muffins.  Speaking of muffins Michelle can remember back when we were in high school we had this volleyball tournament out of town. The hotel offered blueberry muffins at breakfast. And still to this day Michelle can picture those blueberry muffins.

Now you might be thinking why are we talking about muffins when the recipe is a cake. Well, overtime we have come to realize that we prefer cakes over muffins. Therefore, we took our favorite muffin and made it into cute little individual cakes using a bundt pan.

And since blueberries are coming into season we thought this would be the perfect spring/summer treat.

How to make a healthy grain-free, egg-free blueberry streusel cake the right way.

Or should we say purely twins way!

Something we always debate over here is a bundt cake considered to be enjoyed for breakfast/brunch or as dessert?

You know because it’s a cake but they don’t always have a rich creamy frosting like a cupcake. But it’s still sweet like a cupcake, but you can enjoy them at breakfast. Where it is frowned upon eating cupcakes for breakfast. Not saying that we have done that or anything 😉

This blueberry streusel cake is made from just a few ingredients.

Most of them you might have in your kitchen since we know you are like us and always have plantains on hand 😉  We are thinking of investing in a plantain farm since we eat them every day. Wish we could grow them ourselves!! Guess we need to move.

9 FAQ about plantains

We find this recipe to be easy on the gut and digestion as the ingredients are all natural. This cake is full of healthy fats from coconut oil and tahini and made from a safe starch that most people can handle. This recipe is also great for keeping your skin glowing as blueberries are full of antioxidants and low in sugar.

This is a very moist dense bundt cake filled with blueberries topped with a delicious nutty cinnamon streusel. How could you go wrong? Oh wait… there’s no frosting. That’s okay as this cake doesn’t need it! Promise.

For some substitution ideas:

You can replace the almonds for the streusel with any nut or seed (or even oat flour).

You can replace the coconut with any oil or butter of choice. And replace the coconut buttermilk with almond or hemp milk (and use for your buttermilk).

For the tahini we suggest using cashew or almond butter.

For the plantains this is a tough one, you could try using not too ripe bananas.  Bananas that are more little green/yellow like.

Here is how to make this amazing grain-free, egg-free blueberry streusel cake.

This looks absolutely delicious. You ladies never run calorie counts, correct? I understand why; with a recipe like this though, I would love to share it with friends and I have several that refuse to eat my creations unless they’ve got an idea of what’s in it.

purelytwins April 16, 2014 - 1:03 pm

no we don’t really every calculate calories, since the ingredients are usually from real foods, but we know that some people like that.

Sarah April 16, 2014 - 2:41 pm

Hey ladies! Recipe looks delish, but I was actually wondering something totally unrelated…LOL. Where do you all get your cute tanks with all the little sayings on them? For example, I love the red one that says “Be Strong & Do the Work” under Lori’s pic!

Thanks for your website and for these amazing recipes! Because of the two of you, I now eat 1 plantain a day for good carbs!

purelytwins April 16, 2014 - 2:54 pm

Sarah April 16, 2014 - 4:02 pm

OMG, thank you both so much!!! Yay! I will pass this site along to all my girls at Crossfit too…we are tired of all the meathead tanks! LOL

lindsay April 16, 2014 - 4:00 pm

purelytwins April 16, 2014 - 5:10 pm

we make our own – using canned coconut milk and adding in apple cider vinegar! maybe one day there will be an option to purchase at store!

I can’t wait to try these out when the blueberries are in season! Also, love the idea of using the mini bundt pan for pretty little mini cakes… that bundt pan doesn’t get used as much as my muffin tin. Thank you!

Angela May 11, 2014 - 12:28 pm

I finally got a hold of some plantains and I knew exactly what site to go to for a recipe! I would really like to make this for my Mom because it’s grain and egg free but is there a way to sub the nuts and seeds (almond and tahini)? Thanks for your time. I love this site!

purelytwins May 11, 2014 - 5:10 pm

you can see pumpkin seeds flour for the almond meal for the topping, and for the tahini you can try coconut butter or sunflower seed butter.

Angela May 11, 2014 - 8:57 pm

Thanks for the quick response! I was actually looking for a way to make it without nuts or seeds for the autoimmune protocol (maybe I could try coconut butter next time) but decided to make it as is. For some reason mine came out really mushy. Do you think it would be good to add coconut flour? I’ve never used plantain and I was expecting them to be starchier. They were pretty sweet like bananas. The flavor was good but I can still taste the bitterness of the tahini.

Oh yeah, one last question. Where do you get grain-free baking powder? Thanks again!

Angela May 11, 2014 - 8:59 pm

I want to add, I made mine in a 12 muffin tin.

purelytwins May 11, 2014 - 9:39 pm

Angela make sure you are using a green plantain not a ripe one. The more green they are the more starchier it is. You can add coconut flour maybe 1 tbsp. You can make your own baking powder like this one

Hope this helps!

Angela May 14, 2014 - 11:03 am

Thanks, I will try greener plantains next time. Also thanks for the baking powder recipe! I can’t wait to use it. 🙂
