Chocolate Orange & Sweet Potato Bundt

This chocolate orange bundt cake with sweet potato truly is delicious and light.  Made with a relatively small quantity of refined sugar, the sweet potato adds a little extra sweetness as well as bringing vitamins and minerals to the baked treat.   It really has to be tried to be believed.
    
Chocolate Orange and Sweet potato Bundt Cake

Chocolate and orange is a classic flavour combination that we all know and love.  But sweet potato in a cake?  Surely not?  Well believe me, it really does work.  Rather than being heavy and stodgy as you may imagine a bake with potato to be, this cake is seriously light and packed full of delicious chocolate orange flavour. 

Baking with potatoes
I was first introduced to cakes made with potatoes a few short weeks ago when the lovely Sarah over at Tales From The Kitchen Shed shared her recipe for Chocolate Potato Muffins.  They truly looked and sounded amazing.  Like all of her recipes, her step-by-step instructions made it clear that the muffins were a doddle to make.  That week, before visiting my parents, I made a small batch in the form of mini bundts cakes.  My parents, like Sarah's tasters, certainly couldn't tell that the mixture included mashed potatoes.  As Sarah explains the inclusion of mashed potato in bakes is nothing new, it was widely used during the second world war when traditional baking ingredients were heavily rationed.  She goes onto say that the potato rich batter results in a beautiful bake, which I couldn't agree more with, that stays moist for two or three days when stored in an airtight container.



Now Sarah suggests using left over mashed potatoes for the cake, or even cooking a little extra for the purpose of the bake.  However my darling Mr E loves his potatoes in all of their guises, and to put it simply there is never any left when they've been on our menu.  Never.  Not even in the ricer!  In our home town in Yorkshire we regularly used to see a potato delivery van with the phrase 'eat more potatoes' emblazoned across it when we passed a local cafe it was supplying to.  Every time we saw it it would make us chuckle because of Mr E's love of the humble tuber.  So, as you've no doubt realised, I had to make these potato chocolate muffin bakes with fresh mash when Mr E was out of the way ;-)   If you live in a, dare I say, less greedy household than ours then Sarah's logical suggestion is clearly the way to go.  But for me, that little bit of extra preparation for this bake certainly didn't put me off making them again as they were so good.          

Sweet Potatoes in baking

Having enjoyed Sarah's recipe so much I knew I wanted to make it again, but like all keen cooks I decided to play around with the recipe a wee bit.  In this version, I added a generous amount of orange zest to the mixture in place of the expresso coffee powder.  I also used an orange yogurt rather than a plain one or buttermilk to add to that orange flavour.  And rather than use the white potato I decided to try the sweet potato.  It worked really well and I feel it added a little extra bit of sweetness to the bake, though without doing a Side-by-Side Bake it's difficult to say for sure.  The sweet potato also brings with it  many extra health benefits when compared to the widely used white potato.  Health essentials makes a clear tabulated comparison against the two staples.  The sweet potato is shown to be packed with vitamin A, essential for eye health, and is also richer in Vitamin C as well as containing extra minerals then the white potato.  Although it has more sugar than its counterpart, which possibly explains why the cake seemed a little sweeter, the sweet potato is actually lower in calories.   

Chocolate Orange Bundt Cake with Sweet Potato

Besides using a different flavour and potato to Sarah's muffins, I was also keen to christen my new bundt tin!  I just love them, they're so pretty.  As the cake takes on the shape of the tin they need very little in the form of decoration.   Well at least that's the theory.  Having made a school girl error and prepared my tin with white flour rather than cocoa I felt the need to dress it with a chocolate ganache to hide the white shadow which was evident around the side of the cake.  It was no bad thing, though, as it brought extra chocolate flavour to the affair :-) 

Chocolate Orange & Sweet Potato Bundt Cake

This chocolate orange and sweet potato bundt cake is seriously delicious and certainly one I'll make again.  Thank you to Sarah for the inspiration, and if you've never visited her at Tales From The Kitchen Shed I certainly recommend that you pop over, she writes a great food blog.     

  

So let's get to it and bake!

Inspired by: Chocolate Potato Muffins by Tales From The Kitchen Shed

You will need:

1 x large Bowl
1 x Medium Bowl
Grater
Sieve
Spatula or large Metal Spoon
Bundt Tin (ours is 21cm diameter and 10cm high)
Small Pan

For the sponge mixture

A little margarine or butter, for preparing the bundt tin
300g Plain Flour
50g Cocoa Powder, plus extra for preparing the bundt tin
3 tsp (level) Baking Powder
3/4 tsp Bicarbonate of Soda
150g Golden Caster Sugar
3 large Eggs, beaten
2 Oranges, zest of
75ml Orange Yogurt
75ml Milk
150ml Sunflower Oil (or any flavourless oil)
225g Mashed Sweet Potato (cold), from around 2 medium sweet potatoes

For the Chocolate Ganache

150ml Double Cream
150g Milk Chocolate
2 capful Orange Extract ( I used this Valencian Orange Extract from Sainsburys)



How to make it:

1.  Pre-heat the oven to 180c / Fan 160c / Gas 4.

2.  Prepare the bundt tin. Thoroughly grease the bundt mould  ensuring that all of the creases and crevasses are buttered along with the funnel.  Add two or three teaspoons of cocoa powder to the tin.  Hold the tin over the sink and rotate the tin to ensure that all of the surfaces have been covered with the cocoa.  Knock out any excess.

3.  Mix together the dry ingredients.  Sieve the flour, cocoa powder, baking powder, bicarbonate of soda and sugar into a large bowl. 

4.  Mix together the wet ingredients. Break the three eggs into a medium bowl and whisk with a fork.  Add the orange zest, orange yogurt, milk and sunflower oil and mix again until well combined.  Add the cold mashed potato and beat again until the mixture is lump free and well combined.   It will be a lovely pinky orange colour at this stage.

5.  Combine the wet with the dry ingredients.  Make a well in the flour.  Pour the wet mixture into the well.  Use a spatula or large metal spoon to gently combine, avoiding over mixing.

6.  Transfer to the bundt tin.  Use a dessert spoon to place around a third of the mixture into the bottom of the tin trying to ensure that it takes the form of the bundt's creases.  Continue spooning the rest of the batter into the tin, ensuring that the batter is relatively level.  The bundt tin will be around half to two-thirds full.

7.  Bake.  Place the tin into the pre-heated oven and bake for about 45 minutes.   The cake will be ready when an inserted skewer comes out clean.

8.  Meanwhile make the chocolate ganache.  Whilst the cake is cooking, pour the cream into a small pan.  Set over a low to medium heat on the hob and allow to warm through.   Whilst the cream is warming use a sharp knife to carefully breakup the chocolate into small pieces.  Transfer the broken chocolate to a pudding bowl.  Once the cream is hot, though not boiling, pour it over the chocolate.  Add the orange extract.  Stir the mixture until it is smooth.  Set it aside to cool. 

9.  Cool.  Once the cake is baked remove it from the oven and allow to cool for about 15 minutes in the tin.  Tap the sides of the tin with your hand a couple of times to help loosen the cake.  Invert the bundt tin over a wire rack to remove the cake.  Allow the cake to cool completely on the wire rack.

10.  Decorate.  Once the cake is cool and the ganache firmed up a little, apply the chocolate mixture to the cake.  Consider peeling the zested oranges and using the orange segments to decorate the top of the cake.

Enjoy.

Notes:

a)  I tend to find sweet potato is a little softer than its white counterpart so as the mash was made for the purpose of this cake I didn't add any milk or butter.
b)  Avoid using flavoured mash.
c)  If you enjoy dark chocolate, consider replacing the milk chocolate in the ganache with a dark chocolate.  
d)  If you find the ganache a little thick stir in a teaspoonful of milk to slacken.

  1. Sweet potato in a cake - what a genius idea! I love that it made the cake lighter too - who'd have thought? I would definitely assumed the trade off for all those extra vitamins would be a denser cake - but no! Your comments about Mr E's love of mashed potatoes did make me laugh - is he the same with sweet potatoes too? Anyway, your cake looks and sounds gorgeous - any chance you could pop some in a jiffy bag for me? ;-) Eb x

    1. Credit really lies with Sarah when she shared those chocolate potato muffins...seriously Eb you have to try them they're so good. You would imagine it to be a much denser cake, but it certainly isn't and although there is a generous amount of baking powder and bicarb due to the plain flour used they certainly don't leave that strange taste in the mouth.
      To be honest Eb, anything starchy and he's there, rice, pasta, potatoes. But his phrase is 'you can never have too many potatoes' ;-) He's funny :-)
      I'm afraid there are only crumbs left, but when I make another (as I shall it was that good) I'll grab a jiffy bag :-)

    1. Nor had I Betty until I tried the original bake a couple of weeks ago, I imagined it would be heavy but knowing Sarah wouldn't share anything that didn't work I was intrigued like you are and gave it a whirl. Do let me know how you get on if you try it :-)

  4. Thanks for mentioning my Chocolate Potato Muffins Angela & for your kind comments. I've found myself meal planning with mashed potato so I can make my muffins, lol. I'm so pleased they provided the inspiration for your Chocolate & Orange Sweet Potato Bundt. I love how you used an orange yoghurt, a brilliant idea to bring out the orange flavour. Really must try your version soon x

    1. I totally agree that chocolate orange is a fab food combo, it's actually one of my favourites. I was very intrigued too Sarah, and I'm so glad I the it. You really can't tell that the tuber is in the cake so it's a great way of bringing extra nutrients into the diet.

  13. This looks so well baked - I love the texture. I've never tried using flavoured yogurts to add flavour. Always thought that perhaps they would not be strong enough. Thanks once again for joining in with #Bakeoftheweek

    1. Thank you Helen, I was really pleased with the bake :-) I must admit the orange yogurt only brought a small amount of orange flavour (hence the addition of the zest also), but as they say every little helps. I used a lemon yogurt in my simnel cakes a few weeks back and that flavour really came through nicely.

  14. These are seriously mouth watering! I would love to eat it right now and the sweet potato soudns fantastic to me, I'm a huge fan of veg cakes, chocolate and beetroot being my favourite (and the main reason I grow beetroot!). I definitely need to try making these, although we don't have any bundt tins, so might need to buy one! Thanks so much for linking up to #HowtoSunday :) x

    1. i have to admit I've never tried a chocolate beetroot cake, it certainly sounds like one I should try. Rather than buying a bundt tin, you could scale back the recipe and make them as muffins (after all it originated as a muffin recipe really).
