What does Toasted walnuts buttercream frosting taste like?

Toasted walnut buttercream is loaded with walnuts as it is based on real walnuts cooked in milk. Nothing artificial just real and natural ingredients. I think this is the reason why it tastes so decadent and it is not overly sweet!

This buttercream is very versatile and can be used as fillings for cookies, cupcakes, cakes, whatever you wish. I have used toasted walnut buttercream in my walnut, whisky and fig macarons, I will be sharing them on my blog soon.
