This has been adapted from a slimming world recipe, I've changed it to make it WW friendly, quite a dense fudgy cake that is a really big serve for only 3sp including topping, and not really mini as per say! so yummy too!
Put weetbix into a large bowl, and add milk, leave for 2-3 mins to soften, then mash with a fork. Beat in all remaining ingredients for the cake. Spoon the mixture evenly into mini loaf tins that have been lined with baking paper ( mine look like a muffin tin only rectangle deep loaf shape).
Cook for 20-25 mins or until a skewer comes out clean, then cool.
In the meantime make your frosting.
In a small bowl, add your ingredients and whisk until smooth, spoon over cakes when they are at room temperature.
Just a note on these, the topping makes a lot, I didn't use all of it on my cakes so they were 3 sp still, if you use ALL the topping on all of the cakes, add another point.
