There’s something magical about the smell of blueberry muffins baking on a lazy Sunday morning. For me, it’s a trip back to my childhood kitchen, where my mom would let me stir the batter and sneak a few extra berries. Now, as a mom myself, I love recreating that warmth for my own kids – and these Blueberry Jam Crumble Muffins are our absolute favorite.

Why You'll Love This Recipe
About the Ingredients
1 1/2 cups (190g) all-purpose flour
Use unbleached all-purpose for best structure. For a whole-grain twist, substitute half with whole wheat flour.
1/2 cup (100g) granulated sugar
Adds sweetness. You can reduce to 1/3 cup if you prefer less sweet muffins.
2 teaspoons baking powder
Ensure it's fresh for a good rise. If you're out, use 1/2 teaspoon baking soda plus 1 teaspoon cream of tartar.
1/2 teaspoon salt
Balances flavors. Sea salt or kosher salt both work.
1 large egg
Room temperature helps incorporate better. If you're vegan, use a flax egg (1 tbsp ground flax + 3 tbsp water).
3/4 cup (180ml) buttermilk
Makes muffins tender. No buttermilk? Mix 3/4 cup milk with 1 tablespoon lemon juice and let sit 5 minutes.
1/4 cup (60ml) vegetable oil
Keeps muffins moist. Melted coconut oil or canola oil work too.
1 teaspoon vanilla extract
Pure vanilla adds depth. You can use vanilla bean paste for extra specks.
1 cup (150g) fresh or frozen blueberries
If using frozen, don't thaw – just toss in flour to prevent sinking.
1/4 cup (80g) blueberry jam
Use your favorite jam or preserves. Seedless is easier for kids.
For the crumble: 1/2 cup (60g) all-purpose flour
This creates the topping. You can use gluten-free flour blend if needed.
1/4 cup (50g) brown sugar, packed
Adds a caramel-like flavor. Light or dark both work.
3 tablespoons (42g) cold unsalted butter, cubed
Cold butter is key for a crumbly texture. If salted, skip the extra salt in the crumble.
Tips & Tricks
Don't overmix the batter
Mix until just combined, a few lumps are fine. Overmixing develops gluten and makes muffins tough.
Fold blueberries gently
To prevent them from sinking, toss them in a tablespoon of flour before adding.
Fill muffin cups evenly
Use an ice cream scoop for uniform muffins that bake evenly.
Pro Tips
Step-by-Step Instructions
1. Preheat and Prep
Preheat your oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease with butter.
2. Mix Dry Ingredients
In a large bowl, whisk together flour, sugar, baking powder, and salt. This ensures even distribution of leavening.
3. Combine Wet Ingredients
In a separate bowl, beat the egg lightly, then whisk in buttermilk, oil, and vanilla until well combined.
4. Make the Batter
Pour the wet ingredients into the dry and gently fold with a spatula until just moistened. The batter will be lumpy – that's okay.
5. Add Blueberries
Toss the blueberries with a teaspoon of flour, then fold them into the batter carefully to avoid breaking them.
6. Fill Muffin Cups
Divide the batter evenly among the 12 muffin cups, filling each about 2/3 full. Then drop a small spoonful of jam (about 1 teaspoon) into the center of each.
7. Prepare Crumble
In a small bowl, combine flour and brown sugar. Cut in cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs. Sprinkle over the muffin tops.
8. Bake to Perfection
Bake for 18-22 minutes, until the tops are golden brown and a toothpick inserted into the muffin (avoiding jam) comes out clean. The crumble should be crisp. Let cool in the pan for 5 minutes, then transfer to a wire rack.
Delicious Variations
Lemon Blueberry
Add 1 tablespoon lemon zest to the batter and substitute lemon curd for jam.
Mixed Berry
Use a mix of raspberries, blackberries, and blueberries, and any berry jam.
Streusel with Nuts
Add 1/4 cup chopped pecans or walnuts to the crumble mixture for extra crunch.
How to Store Blueberry Jam Crumble Muffins
Refrigerator
Store in an airtight container at room temperature for up to 3 days. For longer freshness, keep in the fridge for up to a week.
Freezer
Freeze muffins in a freezer-safe bag for up to 3 months. Thaw overnight in the fridge or warm in the microwave for 20 seconds.
Reheating
Reheat in a 300°F (150°C) oven for 5-7 minutes to revive the crisp crumble.
Frequently Asked Questions
Q: Can I use frozen blueberries?
Yes, you can use frozen blueberries without thawing. Toss them in a little flour to prevent them from sinking and bleeding color.
Q: Why did my muffins sink in the middle?
Muffins sink if the batter is overmixed or if the oven temperature is too low. Make sure to mix just until combined and preheat properly.
Q: Can I make these gluten-free?
Absolutely! Use a 1:1 gluten-free flour blend for both the muffin batter and the crumble topping. The texture may be slightly different but still delicious.
Q: How do I keep the jam from sinking to the bottom?
Gently place the jam in the center of the batter and cover it with a small amount of batter. Avoid pressing it down.
