If you've ever wondered what exactly sour cream is, here's the deal: it's regular dairy cream that's been "soured" with the addition of bacteria. When the bacteria meets the cream, fermentation occurs, and the cream thickens and gets that characteristic tang.
Sour cream doesn't necessary get a lot of love, but personally I can't imagine chili, nachos, or latkes without it. And that's just on the savory side—sour cream has the ability to make the crumb of baked goods exceptionally tender and give frosting and cheesecakes an important flavor boost.
So the question isn't if you should use it in dessert, it's what to with that half container you have leftover. From ice cream to muffins, here are some ideas.
Blackberry Sour Cream Bundt
Cinnamon Apple Sour Cream Cake with Spelt

Extra Crumb Coffee Cake

Blackberry Crumb Cake
