Blueberry streusel muffins

There’s nothing better than the smell of freshly baked muffins filling your kitchen, especially when they’re packed with juicy blueberries and topped with a buttery, crumbly streusel. These Blueberry Streusel Muffins are soft, fluffy, and bursting with flavor, the perfect treat for breakfast, brunch, or an afternoon pick-me-up.

The secret to these muffins is the double hit of moisture from Greek yogurt and buttermilk, which makes them incredibly tender. And the crunchy streusel on top? It’s what takes these muffins from homemade to bakery-worthy.

Ingredients

Streusel Topping:

• ¼ cup unsalted butter, melted

• ⅓ cup granulated sugar

• ⅔ cup all-purpose flour

Muffin Batter:

• ½ cup unsalted butter, melted

• 1 cup sugar

• 2 large eggs

• 1 tsp vanilla bean gel

• 6 tbsp Greek yogurt (or sour cream)

• 6 tbsp buttermilk

• 1 tbsp baking powder

• ½ tsp salt

• 2 cups all-purpose flour

• 2 cups frozen blueberries (tossed in a little flour)

Instructions

1. Preheat your oven to 400°F and line a muffin pan with paper liners.

2. Make the streusel by mixing melted butter, sugar, and flour with a fork until crumbly, then set aside.

3. In a large bowl, whisk together sugar, melted butter, and eggs. Add the yogurt, buttermilk, and vanilla bean gel and stir until smooth.

4. Mix in the flour, baking powder, and salt until just combined. Coat your frozen blueberries in flour and gently fold them into the batter, being careful not to overmix (so your batter doesn’t turn blue).

5. Scoop the batter into your prepared liners, filling them all the way to the top. Generously top each muffin with streusel, gently pressing it into the batter so it sticks.

6. Bake at 400°F for 6 minutes, then reduce the oven temperature to 375°F and continue baking for another 15 minutes, or until the tops are golden and a toothpick comes out clean.

7. Cool slightly before enjoying, though they’re amazing warm, straight from the oven!

Tips & Tricks

• Extra tall muffins: Starting at a higher temperature for a few minutes helps create that perfect bakery-style dome.

• Frozen berries are key: They help prevent the batter from turning gray and keep the muffins moist.

• Make ahead: These muffins freeze beautifully, just reheat in the microwave for 20–30 seconds.

These muffins are soft, buttery, and have just the right amount of sweet crumble on top. Pair with a hot cup of coffee or tea, and you’ve got yourself the ultimate cozy morning treat.
