Why I Love This Recipe
Before we get to the recipe can we discuss the fact that I might be in your living room this month?! Yup! This California girl is going be making the rounds on morning television and radio stations to share my cooking tips to show you just how versatile walnuts are – check out these walnut sticky buns and this spicy walnut pasta. That way if you get the channel I’m on – we can hang out! I’ve come up with 4 recipes (one of which being these Blueberry Crumb Cakes with Walnut Streusel) that I’ll be sharing and I know you’ll love them all.
Okay, onto the Blueberry Crumb Cakes with Walnut Streusel. These little mini cakes can be dessert, breakfast, a snack – they can be just about anything you want them to be! They are addictive and easy! The batter is a super simple cake batter that’s laced with blueberries and the walnut streusel on top is like candy.

Or make them ahead of time and bring them to your next at home brunch. I promise you’ll be obsessed.

Tips & Tricks
I like to bake the blueberry crumb cakes in muffin tins for easy individual servings, but you could also bake it in a 9x9" baking pan for 50-60 minutes or until a toothpick can be inserted in the center and comes out clean.
FAQs
Can I use frozen blueberries?
Yes, you can use frozen blueberries if that is all you have. Make sure you use them frozen so that they are easier to work with and do not get crushed when folding them into the batter.
Can I make these with other berries?
Certainly. I have a version with strawberries - Strawberry Muffins with Walnut Streusel, but you can try other berries as well!
