This Cinnamon Crumb Blueberry Zucchini Muffins recipe comes together in about 30 minutes and is baked to perfection for a quick and easy breakfast treat or snack that your family will love! You can switch up the blueberries for whatever fruit you have on hand, strawberries or even diced apples work beautifully!
The Ingredients You’ll Need
Here’s what you’ll need to create these ridiculously yummy muffins that will definitely become a staple in your house:
- 1 cup grated zucchini: This will bring in moisture and a lovely texture, plus it’s a sneaky way to add in some veggies!
- 1 cup blueberries (fresh or frozen): I usually go for fresh during the summer when they’re sweet and juicy, but frozen work just as well!
- 1 cup all-purpose flour: Plain ol’ flour works wonders here!
- 1/2 cup brown sugar: This adds depth and a hint of caramel flavor.
- 1/2 cup granulated sugar: For that classic sweetness and delightful muffin texture.
- 1/2 cup vegetable oil: It keeps these muffins moist and tender, definitely don’t skip it!
- 2 large eggs: They help bind everything together and add fluffiness.
- 1 tsp vanilla extract: Because muffins without vanilla? Nah, that’s just wrong.
- 1 tsp baking powder: A must-have for a good rise.
- 1/2 tsp baking soda: This helps balance acidity and gives a little extra lift.
- 1/2 tsp cinnamon: Hello, warm spices!
- 1/4 tsp salt: Just a couple pinches to enhance all those fabulous flavors.
- 1/2 cup crumb topping (made with flour, butter, and sugar): This is where the magic happens, think crispy bits of heaven on top!
Let’s Get Cooking!
How to Make Cinnamon Crumb Blueberry Zucchini Muffins
Preheat the Oven: Preheat your oven to 350°F (175°C) and line a muffin tin with some cute paper liners or grease them with non-stick spray. You want those muffins to pop out perfectly!
Whisk the Wet Ingredients: In a large bowl, whisk together the vegetable oil, brown sugar, granulated sugar, eggs, and vanilla extract until it’s all smooth and beautiful. You’re creating the base here, so mix until it’s all blended.
Add in the Zucchini and Blueberries: Stir in the grated zucchini and blueberries. It’s gonna smell incredible already!
Mix the Dry Ingredients: In another bowl, take your flour, baking powder, baking soda, cinnamon, and salt. Whisk them together until combined. This secondary bowl method helps to ensure that your leavening agents are evenly distributed. You don’t want any surprise pockets of baking soda!
Combine: Slowly, add the dry ingredients to your wet mixture. Stir until just combined, don’t overdo it! You don’t want tough muffins; we’re aiming for delicious, tender bites here.
Spoon into Muffin Tin: Spoon the batter into the prepared muffin tin, filling each cup about 2/3 full. They’re going to rise, and you want them to have space to grow.
Add the Crumb Topping: This part is the best! Sprinkle the crumb topping generously over each muffin. Make sure to cover them well. Trust me, crispy toppings are an absolute game changer!
Bake: Pop them in the oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean. You’re looking for that lovely golden-brown top.
Cool Down: Allow the muffins to cool in the pan for a bit before transferring them to a wire rack to cool completely. It’ll be super hard to wait, but I promise it’ll be worth it!
