If sunshine had a flavor, it would be these muffins. I’m not kidding—these bakery-style lemon blueberry muffins taste like summer mornings, like warm book club chats, like everything good wrapped up in a muffin liner. They’re big, bold, bursting with juicy blueberries, and brightened by zippy lemon zest (it’s in the batter and the crumble). They’re soft and tender inside, with a buttery golden topping that’s chef’s kiss perfect. Whether you’re serving them jumbo-sized for a Saturday brunch or baking minis for a tea party moment, you will love these.
Ingredients:
Granulated Sugar
This sweetens the muffins and helps create a soft, moist crumb. It also helps the tops caramelize beautifully in the oven.Lemon Zest
Zest adds a punch of citrus flavor that’s more intense and aromatic than juice alone. It perfumes the batter and the crumble topping.Unsalted Butter
Melted butter gives these muffins a rich flavor and tender texture. It’s also the base for the crumble, making it golden and crisp.Eggs
They add structure and richness to the muffins. Eggs help the muffins rise and bind everything together.Vanilla Extract
A little vanilla rounds out the tart lemon and adds warmth and complexity to the overall flavor.Sour Cream
This adds a slight tang and loads of moisture, making the muffins soft and plush without being heavy.Lemon Juice
Freshly squeezed lemon juice enhances the citrusy profile and reacts with the baking powder to give the muffins extra lift.Blueberries
Sweet, juicy, and bursting with summer vibes. They pair perfectly with lemon and add beautiful pops of flavor.All-Purpose Flour
Flour provides the structure for the muffin. It also balances the wet ingredients so the muffins rise tall.Baking Powder
This is the leavening agent that helps the muffins puff up like they just came out of your favorite bakery.Salt
A tiny bit enhances all the flavors—don’t skip it.

Bakery Style Lemon Blueberry Muffins with Crumble Topping
Ingredients
- 1 cup granulated sugar
- 1 tbsp lemon zest zest of 1 lemon
- ½ cup unsalted butter, melted
- 2 large eggs
- 1 tsp vanilla extract
- ¼ cup whole milk
- ½ cup sour cream
- ¼ cup lemon juice juice of 1–2 lemons
- 11/2 –2 cups fresh blueberries
- 2 cups all-purpose flour
- 2 tsp baking powder
- ¼ tsp salt
- 3 tbsp melted unsalted butter
- ½ cup all-purpose flour
- ½ cup granulated sugar
- 1 tbsp lemon zest zest of 1 lemon
Instructions
1. Preheat the Oven
- Preheat your oven to 375°F (190°C). This temperature gives the muffins a tall, golden dome without drying them out. Line your muffin tin with paper liners or generously grease each cup with nonstick spray or butter. This recipe makes:
- jumbo muffins
- regular muffins
- –24 mini muffins
2. Prepare Lemon Sugar
- In a large mixing bowl, combine 1 cup granulated sugar and 1 tablespoon lemon zest. Using your fingers, gently rub the zest into the sugar for 1–2 minutes. This releases the oils from the zest and infuses the sugar with bright lemon flavor. The sugar should look slightly damp and smell citrusy.
3. Add Wet Ingredients
- Pour in the ½ cup melted unsalted butter and whisk until fully combined and smooth. The mixture will be glossy and slightly thick.
- Crack in 2 large eggs, one at a time, whisking well after each addition. Add 1 teaspoon vanilla extract and whisk again. The mixture may look a little separated or loose here—don’t worry, it will come together.
- Add in the ¼ cup lemon juice, ¼ cup whole milk, and ½ cup sour cream. Stir gently until smooth and creamy. The batter will be light yellow and slightly thick.
4. Add Dry Ingredients
- In a separate bowl, whisk together 2 cups all-purpose flour, 2 teaspoons baking powder, and ¼ teaspoon salt.
- Using a rubber spatula or wooden spoon, gently fold the dry ingredients into the wet mixture. Stir just until no streaks of flour remain. Be careful not to overmix—this can lead to dense, rubbery muffins.
5. Fold in Blueberries
- Add 1½ to 2 cups of fresh blueberries (you can toss them in 1 tablespoon of flour beforehand to prevent sinking). Gently fold the berries into the batter, using light strokes to keep them whole and evenly distributed.
6. Fill Muffin Tins
- Use a large cookie scoop or spoon to divide the batter into your prepared muffin tin. Fill each cup almost to the top—this gives that iconic bakery-style domed top. Set aside while you prepare the crumble.
7. Make the Lemon Crumble Topping
- In a small bowl, combine ½ cup granulated sugar and 1 tablespoon lemon zest. Rub together with your fingers for that same infused lemon sugar magic.
- Add 3 tablespoons melted unsalted butter and ½ cup all-purpose flour to the bowl. Mix with a fork until crumbly and clumpy—you’re looking for pea-sized and smaller bits. If it’s too wet, add a little extra flour; if it’s too dry, a tiny splash more melted butter.
- Sprinkle the crumble topping generously over each filled muffin. Use your fingers to gently press the crumble into the top so it sticks during baking.
8 .Bake
- Place the muffins into the preheated oven and bake according to your muffin size:
- Mini muffins: 14–16 minutes
- Regular muffins: 20–25 minutes
- Jumbo muffins: 35–40 minutes
- Pro Tip: Start checking for doneness at the early end of the baking range. Every oven is different!
✅ How to Check Doneness
- Insert a toothpick or skewer into the center of a muffin:
- If it comes out clean or with a few moist crumbs, they’re done.
- If it comes out wet with batter, bake for another 3–5 minutes and check again.
- The tops should look lightly golden with a set crumble, and the centers should spring back slightly when gently touched.
9. Cool
- Let muffins cool in the pan for 10 minutes—this helps them firm up and makes them easier to remove. Then carefully transfer to a wire rack to cool completely (or eat one warm… because life is short).

-
Reheat: Warm in the microwave for 15–20 seconds or in the oven at 325°F for 5–10 minutes.
