Chocolate, banana and peanut butter cake for £1

This month's We Should Cocoa challenge run and hosted by Choclette from Chocolate Log Blog challenges us to make a chocolate cake for £1. There is an active fund raising and awareness campaign called Live Below the Line which challenges people to live on £1 a day for 5 days. Participants are asked to spend only £1 per person per day on food and drink. Having made this cake for £1, I am in awe of those who participated in the challenge as I'm not sure if I personally would manage! 

I know I am extremely lucky to live a comfortable lifestyle. I often spend a fair amount on baking and baking related items as you can probably tell from this blog. I have to say I was sceptical about making a cake for £1 as basic ingredients such as butter and eggs cost more than £1. I decided to fully embrace this challenge and to my surprise found out that you can make a delicious cake for only £1. I incorporated my favourite flavours of banana and peanut butter and used regular ingredients that I had at home. I know you can buy cheaper versions but as I only needed a small quantity I decided to work with what I had. My secret ingredient was a packet of Morrison's Saver Sponge mix for only 22p!! I've taken a picture of the shelf in case you don't believe me. The packet instruction says to add 1 egg and 5 tablespoons of water. 

I brought the cake into work and offered it up as usual. I didn't mention that this was a budget cake as I wanted to see everyone's reaction. The comments I got were  "The cake is really light and moist"; "It's really flavourful"; "Can I have the recipe please?" At this point, I'd not tried the cake myself so I had a slice and I was honestly surprised. I really thought it was going to be dry and tasteless as I had my reservations about the sponge mix and the small quantities of peanut butter and cocoa powder. You can clearly taste the banana, peanut butter and cocoa. I think the sour cream added to the lightness of the cake which was my intention hence making sure there was budget for it. If you want to make a chocolate drizzle for the cake then I would recommend reducing the amount of cocoa powder and peanut butter slightly to account for the chocolate. 

The cake I made weighed 482g and I managed to cut it into 9 decent slices as shown which makes it approximately 11p per slice! Definitely a very tasty economical cake.

I'm entering this to several challenges this month.

  4. Oh well done Ros, you've managed to get all sorts of tasty and surprising ingredients in there - including your favourite peanut butter of course. I've never used a cake mix, so have no idea what it contains, but it was a clever idea of yours. Thanks for playing along with this month's somewhat testing WSC challenge.

    1. Thanks for hosting a challenging challenge, I cant wait for the round up. It's amazing what you can make for £1 when you put your mind to it. I'm also glad I manage to work in some peanut butter :)

  5. This looks incredibly moist. Adding banana and peanut butter is a fab idea..... why didn't I think of that????

    1. Ha ha I love banana and peanut butter so it was a no brainer for me :)

  6. Great flavours here - can't believe this cost less than a pound to make. Brilliant entry for this month's Family Foodies challenge. Thanks for sharing :)
