I know that purple potato cupcakes sound crazy, but trust me! The potatoes add bulk and colour, so it tastes like a white chocolate cupcake. I've even used the vibrant spuds to make a white chocolate purple potato frosting.

White Chocolate and Purple Potato Cupcakes
Potato cupcakes?, I hear you cry! Trust me on this. I've baked cakes with mashed potatoes before (check out my chocolate mashed potato cake with tahini drizzle).
Historically, potatoes were often used as a way to bulk out baked goods, particularly during the war. For hundreds of years, bakers used spuds to add bulk and moisture, plus it helps the cakes to keep for longer. You can’t taste the potato and it adds a nice extra richness to these decadent cupcakes. However, these cupcakes don't just have any mashed potatoes, I've used vibrant purple potatoes!
Purple potatoes turn into the most glorious-looking deep purple mash. When adding it to cakes the colour cooks out, a bit like beetroot does in cakes. But it still turns cupcakes this amazing shade of purply blue - naturally. No need to chemical food dyes, just some vibrant potatoes and you can colour these pretty cupcakes. The cupcakes don't taste of potato at all, but taste like a vanilla and white chocolate sponge. They're light, airy and delicious.
The frosting I used more of the purple mashed potato as the base for the frosting. I needed to keep that fab colour! So, the frosting tastes like a scrummy white chocolate frosting. Instead of bulking it out with icing sugar and butter, I used the mash and chocolate, with just a little extra powdered icing sugar. And... voila - potato frosting!

Rebecca @ Strength and Sunshine
Cute! I think I'd use my Stokes Purple Sweets though 😉
The Food Hunter
The color is beautiful. I would make them just for that reason alone!
Gloria @ Homemade & Yummy

Aish Das-Padihari
Amazing colors. Love all the pictures and the purple potato cup cakes sound good.
Bella
These are so cute, the colour is amazing! I don't think I've actually ever seen purple potatoes in the shops before but I'll have to look out for them now!
Marko Stojanovik
Hi, how is this healthy with so much sugar being used? I thought the idea is to provide kids healthy snacks?
Kate Hackworthy
Hi Marko, there's less sugar in these cupcakes than in typical cupcakes. But I'm all about balance - sometimes my kids make quinoa carrot truffles, sometimes we have more decadent cupcakes. These cupcakes have a bit of extra goodness from the purple potatoes, so they're slightly healthier than your average cupcake. If you're looking for sugar-free desserts, then have a search as I have plenty on the blog!
Nico @ yumsome
These are so beautiful - they could actually tempt me to eat cupcakes again!
(Long story... but it involved me being a judge in a cupcake contest years ago. I've not been near one since!)
CJ
Does the icing change colour after a day or two of making the cupcakes?
Kate Hackworthy
Hi, I've had them for four days now and no sign of any change in colour. I wouldn't expect that it will fade before it gets eaten.
CJ
Thank you! They are such beautiful cupcakes!

I love purple potatoes and often serve them mixed with normal potatoes when they are in season, I have never used potatoes in cakes before, though, so this has been very interesting. Such a beautiful colour!
Helen @ Fuss Free Flavours
Just yesterday I watched a recipe that included beetroot in chocolate brownies, and that worked well. Purple poatoes! How fab do they look. I love them, So fab that you have included them in these cupcakes, what a wonderful colour.
