Dreamy Sour Cream Coffee Cake Muffins

Category: Breads and Pastries Without Borders

You’ll get a super buttery, tangy muffin here, thanks to lots of sour cream and a combo of butter and oil. That sweet, crunchy cinnamon streusel isn’t just sprinkled up top—it’s hiding inside too, so every bite pops with flavor. Start with the easy streusel first, then stir up a simple batter with pantry basics—flour, eggs, sugar, vanilla, and of course, tangy sour cream for all the moisture. Pop some batter and streusel into each muffin cup so you’ve got cinnamon through and through. A quick bake and you’re done—golden, tender muffins ready for coffee time or a sweet snack whenever you feel like it.

Nothing beats the comfort of sour cream coffee cake muffins filling your kitchen with that warm smell The sour cream makes every bite so soft and the buttery cinnamon crumble is just heavenly

I tossed the batter together on a chilly Saturday and the smell of cinnamon alone had everyone peeking into the kitchen well before the timer went off

Inviting Ingredients

  • All-purpose flour: Holds everything together and makes the texture fluffy Go for nice fresh flour if you can
  • Salt: Punches up the flavors I like using fine sea salt because it mixes in evenly
  • Baking soda: Works with the sour cream so your muffins rise just right
  • Vanilla extract: Adds a gentle warmth Real vanilla gives the best flavor
  • Baking powder: Makes sure you get muffins with a great dome Always check it’s still fresh
  • Sour cream: The secret to making these so rich and tender Always use full-fat for that plush bite
  • Eggs: Hold the whole thing together and make the muffins rise Large eggs at room temp work best
  • Vegetable or canola oil: Keeps every bite moist and you don’t taste it Neutral oils are ideal
  • Unsalted butter: Brings richness Use good butter and remember to keep it cold for the streusel soft for the batter
  • Granulated sugar: Sweetens the muffins and the topping Make sure it’s not clumpy
  • Ground cinnamon: Brings that cozy spiced flavor Fresh cinnamon packs the most punch

Easy Step Instructions

Cool Down:
Move the muffins from the pan and onto a wire rack Let them chill out so the crumb can get set and ready
Bake Muffins:
Put your tray right in the middle of the oven Bake 15 minutes then poke the center with a toothpick If it comes out clean or with only a crumb they're good If not bake them up to another five minutes
Layer Like a Pro:
Add a big spoonful of batter into each muffin spot Sprinkle plenty of streusel over that Keep layering until liners are about three-quarters full Finish with the rest of the streusel on top
Add the Dry Mix:
Still mixing on low Pour in your dry mix Stop as soon as it's barely combined and scoop with a spatula to catch any flour at the bottom
Add Sour Cream and Vanilla:
With the mixer barely on add sour cream and vanilla Don’t over-mix here—just until it's combined
Drop in Eggs Single-Fashioned:
Add one egg at a time beating just till mixed each go This keeps things smooth and lump-free
Butter Sugar Oil Beatdown:
Grab your mixer or a big bowl and beat the soft butter with sugar and oil Mix 2-3 minutes till it’s pale and almost fluffy
Mix Those Dry Ingredients:
In a new bowl whisk together flour, baking powder, soda, and salt A quick whisk makes sure all the rising power gets spread out Set aside
Make That Streusel:
Grab a bowl, whisk together sugar, flour, and cinnamon Add cold butter Rub it in with a fork or pastry cutter till it clumps together Save it—you’ll need this twice
Oven & Muffin Tin Ready:
Get your oven up to 350 right from the start Line your muffin tin with paper cups for less mess and set aside

Cinnamon’s a must for me with anything like coffee cake I say the more the merrier My little ones always want to help make the streusel and sneak a little taste before the batter even goes in

Keep Them Fresh

Once they’re cool pop the muffins in an airtight container and keep on the counter up to three days Longer than that wrap each in plastic and toss in the freezer for up to two months I stash a few so there’s something special for breakfast on the fly

Swap Options

No sour cream? Try full-fat plain Greek yogurt—works just about the same For no dairy, swap in your favorite plant butter and non-dairy sour cream I’ll sometimes trade out half the all-purpose flour for white whole wheat for a little extra flavor but the texture still stays soft

Tasty Ways To Share

Pair these with a hot mug of tea or coffee and wow They also love a dusting of powdered sugar if you’ve got it On a brunch table, add some fruit and scrambled eggs or pack in a lunchbox for a sweet pick-me-up later

Old School Coffee Cake Origins

This classic is rooted in Old World traditions meant for sipping with coffee or tea The streusel comes from German baking and took off in America My grandma always baked a big pan for holidays and making them as muffins is my version of her memory

FAQs About the Recipe

→ What does sour cream do for muffins?

Sour cream makes muffins crazy soft and stops them from drying out. It adds a gentle tang that isn’t too much, just right for balancing out sweet streusel.

→ Could I swap in Greek yogurt instead of sour cream?

Sure thing! Plain full-fat Greek yogurt gives the muffins that creamy fluff and still keeps them tangy.

→ How come you layer streusel both in the middle and on the top?

Putting streusel inside and on top means you hit cinnamon-goodness in every bite, plus you get that crisp topping too.

→ How’ll I know they’re finished baking?

Stick a toothpick right in the middle—if it’s mostly clean (maybe a few crumbs), you’re good to go!

→ Can these muffins be frozen?

Yep! Let them cool off, wrap tight, and freeze. They’ll last up to 2 months without a fuss.

→ How do you keep any extras fresh?

Seal them up in a container on the counter, and you’ve got about 3 days before they lose their magic.

01 6 tablespoons unsalted butter, chopped up
02 1 teaspoon ground cinnamon
03 1/2 cup granulated sugar
04 1/2 cup regular flour

05 2 teaspoons baking powder
06 1 cup granulated sugar

12 1/2 teaspoon baking soda
13 1/4 teaspoon salt
14 2 teaspoons vanilla

Step-by-Step Guide

Step 01

Once they're done, pull the muffins out and lift each one onto a rack so they can chill all the way before biting in.

Step 02

Toss everything in the oven you already heated up and let them go for about 15 to 20 minutes. They're ready if a toothpick comes out with nothing stuck on it.

Step 03

Put a big spoonful of mix in every muffin liner. Throw a bit of streusel on top, then finish off the batter. Top them off with the rest of the crunchy stuff.

Step 04

Drop your dry stuff into your wet mix a little at a time. Don't overdo the mixing. Use a spatula at the end to make sure nothing's hanging out at the bottom.

Step 05

Turn the mixer down low. Pour in sour cream and a splash of vanilla. Mix until it's just barely stirred in.

Step 06

Break in one egg, beat it in well, then add the second until everything's blended smoothly.

Step 07

In your stand mixer with the paddle, blend the softened butter with the oil and sugar till you get a nice creamy mix.

Step 08

In its own bowl, stir together flour, baking powder, baking soda, and salt so it's all even. Leave it aside for now.

Step 09

Mix flour, sugar, and cinnamon in a bowl. Toss in the butter bits and use a fork or pastry blender to squish everything into chunky crumbs. Set it to the side.

Step 10

Set your oven to 350°F (175°C). Grab a muffin tin, pop liners in, then set it aside while you get the batter ready.

Additional Notes

  1. Don't work the batter too much or your muffins might dry out. Keep it light for a soft result.
