Crumb Cake Muffins

"For these Crumb Cake Muffins, I started with my go-to crumb topping that I’ve used on all sorts of baked goods…most notably, coffee cakes. Then I just went with a very basic base for these muffins to let the crumb topping really shine. But with that said, the muffins themselves are legit. They’re basic, but don’t be surprised if this muffin recipe shows up again with the addition of blueberries, chocolate chips, raspberries, etc. It’s always nice to have a go-to recipe, and this muffin base is a good go-to recipe to file away. The crumb topping itself needs no accolades. Those little brown sugar + cinnamon chunks could be eaten by themselves!"
