I love a quick breakfast, and muffins are one of my go tos, whether it’s a double chocolate zucchini muffins or a peach kuchen muffin. They make a great batch of make ahead meals that everyone eats without complaining.
It’s just a bonus that they are perfect to use up too many blueberries I buy. And yes, they work well with frozen blueberries, too.
Why use muffin papers?
Whenever I make muffins, I use muffin papers instead of greasing the muffin tin. Why?
Well, first, when you spray a muffin tin, it gets sticky and gross where the spray doesn’t get covered by food. It bakes onto the muffin tins and essentially ruins them.
I only use nonstick spray where I have no alternative or where I know whatever I am baking entirely covers the nonstick spray.
Second, the muffin papers make it easier to remove the muffins from the pan in a single piece, always a win.
And the muffin papers help keep the muffins moist the next day.
How to Make Blueberry Sour Cream Muffins
Preheat your oven to 400 degrees. Add muffin papers to the tins, or grease the tins if needed.
I used 36 medium sized tins and 24 mini muffins for this. If you use the standard muffin tins, this makes approximately 42 muffins.
Beat your eggs in a bowl. Add the sugars and continue to beat.
Slowly drizzle in the oil to ensure it emulsifies. Add the vanilla and mix well.
Add half the sour cream and mix well. Add the baking soda, salt and half the flour.
Gently, and oh so slowly, mix until the flour is *mostly* gone. Add the remaining sour cream, following the same strategy.
Add the remaining flour, again mixing just until the flour is mostly gone. You do NOT want to overstir this.
Fold in the blueberries carefully. Scoop into your prepared muffin tins using a muffin scoop to get them as even as possible.
I debated adding a streusel to the top, but in the name of pretending that these were healthy muffins, I decided against it. Ok, so if I were really making this a healthy recipe, I would have used half applesauce with the oil and plain yogurt instead of sour cream. Eh.
Bake at 400 degrees for 20-25 minutes until your cake tester comes out clean.
Enjoy!

Laura – Thanks for the info. I might do that just for the fun of it 🙂 Applesauce cake is up on a post somewhere – I'll try to remember to link that one next week.
Kelly – I'd offer to share, but I took them to the PTO meeting this am and there are only 2 left 🙂
Thanks for entering this in BSI! I love sour cream in baked goods, it makes them so yummy! (Also thanks to Laura for the suggestion to enter it!)
Christina – I'm with you. Although I don't like sour cream in general, it's great as an ingredient. This is a mantra about a ton of foods that I'm drilling into the wee ones!
Cannot save recipe to Pinterest.
Thanks for letting me know! It’s fixed now 🙂
If you want to make jumbo sized muffins, how long is the cooking time?
To make jumbo size muffins (I have not with this recipe, but this is the general rule of thumb so *should* work), you want to lower the oven temp by 25 degrees. You want it to cook slower to cook the whole muffin and not just the outside. Start by adding 5 minutes to the cook time, and check it then. You may need to add another minute or two to that, but that’s a good starting point. Good luck!
