Sweet Potato Loaf with Brown Butter Maple Frosting

This post is sponsored by McCain

How do I like my vegetables, you ask? In cake, of course! You can then imagine how excited I was when McCain approached me to team up with them to create a few exciting recipes.

I grew up eating McCain – being a family of five with a working mom meant quick freezer to table dinners. Whilst my mum used them in dinners, I prefer my vegetables in cake! It can sometimes be a schlep to buy vegetables on demand, peel them and prep them only to then start to bake with them.

I used McCain sweet potato chunks to create this sweet potato cake with a brown butter maple frosting and my veg was prepped in under 10 minutes, in the microwave! I love the convenience of McCain. Even I love a bit of a shortcut now and then. The McCain sweet potato chunks makes this cake moist but has a close crumb structure.
