How Long to Bake Blueberry Muffins at 375°F: Mini, Standard, Jumbo
Bake blueberry muffins at 375°F (190°C) for 12 to 15 minutes if mini, 18 to 24 if standard and 25 to 30 if jumbo. Doneness tests and fixes included.

Blueberry muffins bake at 375°F (190°C) for about 12 to 15 minutes in a mini pan, 18 to 24 minutes in a standard pan and 25 to 30 minutes in a jumbo pan. They are done when a toothpick comes out with a few moist crumbs and the tops spring back lightly. Ovens differ, so start checking a few minutes before the shortest time.
How long do blueberry muffins bake at 375°F?
The time depends on the size of the cup. Larger muffins have more batter in the center, so heat needs longer to reach it.
- Mini muffins: 12 to 15 minutes
- Standard muffins: 18 to 24 minutes
- Jumbo muffins: 25 to 30 minutes
These are ranges for a typical batter and a conventional oven. Dense batters, extra fruit and dark metal pans can shift the time by a few minutes. For other muffin types and oven settings, see the muffin time and temperature chart.
How do you know blueberry muffins are done?
Use more than one check. The tops should be golden and dry, and they should spring back when you press them gently. A toothpick pushed into a spot without a berry should come out clean or with a few dry crumbs. Wet batter on the pick means the muffin needs more time. If the pick hits a berry, the jammy smear is fruit, not raw batter, so try another spot.
A thermometer is the most precise tool. Muffins are generally fully baked when the center reaches roughly 200 to 205°F (93 to 96°C). If a thermometer is not at hand, lift one muffin out of the pan and check that the sides and bottom look set.
How full should you fill the cups?
Fill standard cups about two-thirds to three-quarters full. That gives a domed top without spilling over the edge. Mini cups can be filled to about the same level. Jumbo cups follow the same rule, but the extra batter is the reason for their longer time. If you are switching pan sizes, our guide to muffin pan sizes and batter amounts shows how much batter each cup takes and how the time changes.
Overfilled cups bake into flat, wide tops that stick to the pan and can look undercooked in the middle even when the edges are dark. Underfilled cups bake faster and dry out.
Do fresh and frozen blueberries change the bake time?
Frozen blueberries release more water, and they cool the batter around them. Do not thaw them first, since thawed berries bleed color into the batter. Fold them in at the last moment and expect to add a few minutes to the bake time. Tossing either kind of berry in a spoonful of flour before folding helps keep them from sinking to the bottom.
Why are my blueberry muffins dry or raw in the middle?
Dry muffins usually baked too long or in an oven that runs hot. Raw centers come from an oven that runs cool, an overfilled cup or a pan that was opened too early. An oven thermometer shows the true temperature, since many ovens are off by 25°F (about 14°C) or more. Avoid opening the door in the first 15 minutes of baking, because the heat drop can stop the rise.
- Dark tops with a pale center: lower the rack position and move the pan to the center of the oven.
- Sunken tops: the oven was too cool, or the batter was overmixed.
- Soggy bottoms: cool the muffins in the pan for 5 minutes, then move them to a wire rack.
- Berries sinking: toss them in flour and use a thicker batter.
Can you use a different oven temperature?
Yes. Some bakers start hot at 425°F (220°C) for the first 5 to 7 minutes to get a tall dome, then lower the oven to 375°F (190°C) to finish. This works for standard muffins, but watch the tops closely. If your recipe is written in Celsius, our guide to baking muffins at 180°C covers fan and conventional ovens.
Does the pan material matter?
Yes. Dark metal pans absorb more heat and brown the bottoms faster, so check them a couple of minutes early. Light aluminum pans bake more gently, and silicone cups need a little longer. Paper liners barely change the time, but they do make cleanup easier and keep sticky berry juice off the pan.
Quick answers
Can you bake mini and standard muffins in the same oven at once?
Yes, but they finish at different times. Check the minis at 12 minutes and take them out first, then leave the standard pan in.
How should you store blueberry muffins?
Let them cool completely, then keep them in an airtight container at room temperature for a day or two. For longer storage, freeze them in a sealed bag.
What if my muffins are done on top but wet inside?
Tent the pan loosely with foil and bake another 3 to 5 minutes, then test again. The foil stops the tops from browning too much.
