You can't beat a good bit of Mr. Kipling, and I was certainly drawn in by the promise of cake that tastes like milkshake, especially when two flavours were involved. These slices are compositionally similar to other Mr. Kipling offerings, chocolate and vanilla milkshake sponge layers, glued together with a creamy filling and topped with icing.
Unfortunately, they're not as great as I'd hoped. The cake is certainly cake-like, but it's certainly not very milkshake-like. You'd expect it to be light and creamy, but instead the sponge is quite stodgy, and while the flavours are certainly chocolate and vanilla in origin, they're just quite heavy and nowhere near milky enough for my liking. There is a saving grace in the form of the creamy filling and topping, and overall it makes for a not wholly terrible cake, but if you're looking for a milkshake experience you won't really find it here.
My rating: 2/5
