Banana Muffins Recipe

I’m laughing as I’m writing this Sour Cream Banana Muffins post because my kids just said, “You can only make that much?! It’s going to be gone before dad gets home.” And yes, that’s all I can make because I don’t have anymore bananas….geez. So I’m guessing that this Sour Cream Banana Muffins recipe is going into the “keep” recipe pile.

If your house is like ours, we always end up with two or three overripe bananas. Usually, I’ll slice up the bananas before it gets too overripe and freeze them for smoothies. However, these two were pushed behind my rice cooker and too soft to slice up. So what better thing to make than Sour Cream Banana Muffins? YUM!

Hope you all enjoy!
