What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and substitutions are easy if needed.

• All-purpose flour (1 ½ cups / 190g) – the base for a tender crumb
• Baking powder (2 teaspoons) – helps muffins rise nicely
• Sodium bicarbonate (baking soda) (¼ teaspoon) – adds extra lift
• Salt (¼ teaspoon) – balances the sweetness
• Granulated sugar (¾ cup / 150g) – for sweetness
• Unsalted butter (6 tablespoons / 85g), melted and cooled – adds richness (I prefer Kerry Gold for that creamy flavor)
• Large eggs (2), room temperature – binds ingredients, adds moisture
• Buttermilk (½ cup / 120ml), room temperature – tenderizes and adds tang (sub with milk + 1 tsp lemon juice if needed)
• Vanilla extract (1 teaspoon) – for warmth and depth
• Lemon zest (1 teaspoon) – brightens the flavor
• Fresh blueberries (1 cup / 150g) – juicy star ingredient (in summer, swap in fresh berries; frozen works too but toss with a little flour first)

For the Crunchy Streusel Topping:

• All-purpose flour (½ cup / 65g)
• Brown sugar (⅓ cup / 70g) – adds a caramel-like sweetness
• Cold unsalted butter (4 tablespoons / 55g), cubed – creates the crunch
• Cinnamon (½ teaspoon) – warm spice note
• Pinch of salt – balances the topping

Feel free to swap all-purpose flour for gluten-free flour blend if needed, or use coconut sugar instead of brown sugar for a different flavor twist. These ingredients come together to make easy blueberry muffins with crunchy streusel topping that taste like a bakery treat but are super simple to make at home.

Equipment Needed

• Muffin tin (12-cup) – essential for shaping these beauties; silicone or metal both work fine
• Mixing bowls – one for dry ingredients and one for wet
• Whisk and spatula – for mixing batter gently without overworking
• Measuring cups and spoons – accuracy matters for baking success
• Cooling rack – helps muffins cool evenly and keeps that streusel crunchy
• Optional: Electric hand mixer or stand mixer can speed up the process, but I often do this by hand to avoid over-mixing

Pro tip: If you don’t have a muffin tin, mini loaf pans or even ramekins (greased well) can work as alternatives—just adjust baking time accordingly. For the streusel, a pastry cutter or two forks make quick work of cutting butter into flour, but your fingers work just as well!

Preparation Method

1. Preheat your oven to 375°F (190°C) and line a 12-cup muffin tin with paper liners or grease it well. This sets the stage for perfectly baked muffins.
2. Prepare the streusel topping: In a small bowl, combine ½ cup (65g) all-purpose flour, ⅓ cup (70g) brown sugar, ½ teaspoon cinnamon, and a pinch of salt. Add 4 tablespoons (55g) cold, cubed unsalted butter.
3. Cut the butter into the dry mixture using a pastry cutter, two forks, or your fingers until it resembles coarse crumbs. Set aside in the fridge to keep cold while you prepare the batter—this helps the topping stay crunchy during baking.
4. Mix dry ingredients for the batter: In a large bowl, whisk together 1 ½ cups (190g) flour, 2 teaspoons baking powder, ¼ teaspoon baking soda, ¼ teaspoon salt, and ¾ cup (150g) granulated sugar until combined.
5. Mix wet ingredients: In a separate bowl, whisk 2 large eggs (room temperature), 6 tablespoons (85g) melted and cooled unsalted butter, ½ cup (120ml) buttermilk, 1 teaspoon vanilla extract, and 1 teaspoon lemon zest until smooth.
6. Combine wet and dry ingredients: Pour the wet mixture into the dry ingredients and gently fold with a spatula until just combined. Be careful not to overmix—some lumps are okay. Overmixing can lead to dense muffins instead of light and tender ones.
7. Fold in the blueberries: Gently toss 1 cup (150g) fresh blueberries with a tablespoon of flour (to prevent sinking) and fold them carefully into the batter.
8. Fill muffin cups: Divide batter evenly among the 12 muffin cups, filling each about ¾ full.
9. Top generously with streusel: Remove the streusel from the fridge and sprinkle it evenly over each muffin, pressing lightly to adhere.
10. Bake for 20-25 minutes or until a toothpick inserted in the center comes out clean and the tops are golden brown. If your oven runs hot, start checking at 18 minutes to prevent over-browning.
11. Cool muffins in the tin for 5 minutes, then transfer to a wire rack to cool completely. This keeps the bottoms from getting soggy and preserves that crunchy topping.

Pro tip: If your streusel starts browning too fast, tent loosely with foil for the last few minutes of baking. Also, fresh blueberries give the best flavor, but frozen work in a pinch—just don’t thaw before mixing!

Cooking Tips & Techniques

Getting perfect muffins every time can feel tricky, but here are some tips I’ve learned along the way:

• Don’t overmix the batter. This is the biggest mistake. Mix just until the wet and dry ingredients come together. A few lumps are fine! Overmixing develops gluten and makes muffins tough.
• Keep your butter melted and cooled. Warm butter blends easily with eggs and buttermilk, helping create a tender crumb without clumps.
• Use fresh or properly frozen blueberries. Tossing them in flour prevents sinking to the bottom and keeps them evenly distributed.
• Chill your streusel topping before baking. Cold butter in the topping melts slowly, creating that signature crunch instead of a greasy mess.
• Test doneness carefully. Ovens vary, so start checking with a toothpick at 18 minutes. The tops should be golden and firm to the touch.
• Multitasking: While muffins bake, clean up your prep area or prepare coffee to maximize your time. Baking’s all about efficiency!

One time, I forgot to add baking powder and ended up with muffins as flat as pancakes—lesson learned. Always double-check your ingredients before mixing!

Variations & Adaptations

These easy blueberry muffins with crunchy streusel topping are versatile. Here are some ways to make them your own:

• Dietary: Swap all-purpose flour for a gluten-free blend for gluten sensitivity. Use coconut sugar instead of white or brown sugar for lower glycemic impact.
• Seasonal: Replace blueberries with raspberries, blackberries, or chopped fresh peaches in summer. In fall, try diced apples with extra cinnamon in the streusel.
• Flavor twists: Add a teaspoon of almond extract for a nutty note or a handful of chopped nuts (walnuts or pecans) to the streusel for extra crunch.
• Cooking method: Muffins can be baked in mini muffin tins for bite-sized treats—reduce baking time to 12-15 minutes to avoid drying out.
• Personal variation: I once swapped buttermilk for Greek yogurt and added a tablespoon of honey to the batter, which gave the muffins a lovely tang and subtle sweetness—definitely worth trying!

Serving & Storage Suggestions

Serve these blueberry muffins warm or at room temperature, ideally within a few hours of baking to enjoy the contrast between soft interior and crunchy streusel topping. They’re perfect alongside a hot cup of coffee, tea, or a glass of cold milk.

For brunch, pair them with scrambled eggs or a fresh fruit salad to balance sweetness with something savory and fresh. These muffins also make wonderful grab-and-go snacks for busy mornings.

To store, keep muffins in an airtight container at room temperature for up to 2 days. For longer storage, freeze them individually wrapped in plastic wrap and then placed in a freezer bag for up to 3 months. To reheat, pop frozen muffins in a 350°F (175°C) oven for about 10 minutes or microwave for 20-30 seconds (though oven reheating preserves the crunch better).

Flavors tend to deepen after a day, so if you can wait, they taste even better the next morning. Just be sure to refresh the crunch by reheating briefly in the oven.

FAQs

Can I use frozen blueberries instead of fresh?

Yes! Just toss frozen blueberries with a tablespoon of flour before folding into the batter to prevent them from sinking and turning the batter blue.

How do I keep the streusel topping crunchy?

Keep the butter in the streusel cold until right before baking, and don’t cover the muffins tightly after baking. Reheating briefly in the oven also helps restore crunch.

Can I make these muffins dairy-free?

Absolutely! Substitute buttermilk with dairy-free milk mixed with a teaspoon of lemon juice, and use dairy-free butter or coconut oil for the batter and streusel.

What’s the best way to store leftover muffins?

Store at room temperature in an airtight container for up to 2 days, or freeze individually wrapped for up to 3 months. Reheat in the oven for best texture.

Can I add nuts or other mix-ins?

Yes! Chopped nuts like walnuts or pecans work great in the streusel or batter. You can also add a handful of chocolate chips or swap fruit seasonally.
