Blueberry Muffins with Frozen Blueberries are soft, moist, and easy to make—perfect for a quick bake any day.

These muffins are one of those recipes I come back to often.
Soft, very moist, and simple to prepare—they don’t need much time or many ingredients. I have a few versions of blueberry muffins, some more elaborate, others quicker, like this one. It really depends on the day and what I have on hand.
This version is fast but still delivers great texture and flavor. And if you’re using frozen blueberries, there’s a little trick—the juice they release can slightly tint the batter blue. For me, that’s part of their charm.
How to choose the best ingredients for blue moist blueberry muffins
Butter: Use real butter only—no blends. It gives the best flavor and texture
Buttermilk: You can replace it with kefir or yogurt. Room temperature works best for a smoother batter
All-purpose flour: Regular flour is perfect. Sift it before adding to keep the muffins light
Starch: Helps keep muffins moist longer and makes them fluffier. You can use potato or corn starch—both work the same
Sugar: Use any sugar you like. White sugar works well and keeps the flavor clean
Blueberries: Frozen blueberries are great here—they release juice during baking, which naturally gives the muffins a slightly blue color inside

Top Tip for Success
- To bring buttermilk to room temperature quickly, place the glass in warm water and stir from time to time so it heats evenly
- Melt butter only about ⅔, then remove from heat and let the rest melt from residual warmth—this prevents overheating
- Don’t overmix the batter—mix just until combined so the muffins stay soft and fluffy
- If using frozen blueberries, add them straight from the freezer and lightly toss in flour to prevent them from sinking
- Fill muffin cups about ¾ full—they will rise nicely without overflowing
- For a nicer top, sprinkle a little sugar before baking—it creates a light crust
- Let muffins cool slightly before removing from the pan—they will hold their shape better
- They taste even better after a few hours, once the flavors settle
