Banana Walnut Muffins with Struesel Topping

I was going to make some berry muffins with streusel topping, but had some bananas I was going to make into banana bread.v So I mashed the two ideas and since when making muffins, it’s go big or go home, I made jumbo banana walnut muffins. The recipe I found on Sally’s Baking Addiction makes 10-12 muffins, I got 6.

Apparently, my streusel recipe makes a ton, so feel free to cut it in half or pop the remainder into the freezer or use to top a rhubarb cream pie!
