There is nothing cozier than a batch of sour cream coffee cake muffins warming up the kitchen The rich tang from sour cream gives an incredibly soft crumb and the buttery cinnamon streusel makes each bite irresistible
I baked these on a chilly Saturday morning and the smell of cinnamon brought everyone to the table before they were even out of the oven
Ingredients
- Allpurpose flour: provides structure and a soft texture Use fresh flour for best results
- Granulated sugar: sweetens both the batter and the streusel You want it to be free of any lumps
- Ground cinnamon: gives the classic spiced flavor Go for fresh or recently purchased for the best aroma
- Unsalted butter: adds richness Always bake with good quality butter and make sure it is truly soft for the batter and cold for the streusel
- Vegetable or canola oil: keeps the muffins extra moist Neutral oils work best so the flavor stays pure
- Eggs: bind everything together and help the muffins rise Choose large and at room temperature for easy mixing
- Sour cream: makes these muffins plush and tender Use fullfat sour cream not low fat
- Baking powder: lifts the muffins for a dome without being dry Always check your baking powder is not expired
- Baking soda: balances the acidity of the sour cream for an even rise
- Salt: brings out all the flavors Use a fine sea salt for best dispersion
- Vanilla extract: rounds out the flavor with warmth Pick pure vanilla extract for the richest taste
StepbyStep Instructions
- Prep the Oven and Muffins Tin:
- Get your oven heating to three hundred fifty degrees right away Line a standard muffin tin with paper liners for easy cleanup and set it aside
- Make the Streusel:
- In a bowl combine the flour sugar and cinnamon with a whisk so everything is evenly mixed Add the cold butter pieces and work them in with a fork or pastry cutter Keep pinching and mixing until you have a crumbly mixture that sticks together in clumps Set this aside as you will use it twice
- Mix Dry Ingredients for Batter:
- In a separate bowl whisk together your flour baking powder baking soda and salt Give it a few passes with the whisk to make sure the leaveners are distributed evenly Set aside
- Cream Butter Sugar and Oil:
- In the bowl of a stand mixer or a large mixing bowl beat the softened butter with the sugar and oil This should take two to three minutes until the mixture looks pale and fluffy
- Add Eggs One by One:
- Mix in one egg at a time let each one beat in completely before you add the next This makes the batter smoother and less likely to curdle
- Incorporate Sour Cream and Vanilla:
- With the mixer on low gradually add in the sour cream and vanilla Only mix until these are just combined so you do not overwork the batter
- Add Dry Ingredients:
- Now with the mixer still on low carefully pour in your dry ingredient blend Stop the mixer as soon as you see no more flour streaks then use a spatula to fold the batter once to scoop up any unmixed streaks from the bottom
- Layer Batter and Streusel:
- Spoon a generous tablespoon of batter into the bottom of each prepared muffin cup Sprinkle a good pinch of streusel topping over the batter Repeat layering with the rest of the batter until the liners are threequarters full Finish each muffin with the remaining streusel
- Bake:
- Place your filled muffin tin in the center rack of the oven Set a timer for fifteen minutes and check with a toothpick at the center of a muffin If it comes out clean or with just a crumb or two they are done If not bake up to five minutes longer
- Cool:
- Take the pan out and gently lift the muffins out onto a wire rack Let them cool completely so the crumb can set

Cinnamon has always been a must for me in coffee cake You can never have too much of that sweet spice My kids love to help with the streusel and always sneak a pinch for themselves before the muffins even go in the oven
Storage Tips
Once the muffins have cooled store them in an airtight container at room temperature for two to three days For longer storage wrap each tightly in plastic and freeze for up to two months I often freeze a few so I can enjoy a homemade treat on busy mornings
Ingredient Substitutions
If you do not have sour cream you can use plain full fat Greek yogurt for similar results For a dairy free version use your favorite plant based butter and sour cream Many times I have swapped white whole wheat flour for half of the allpurpose It adds a bit of extra nuttiness without affecting texture
Serving Suggestions
These muffins really shine alongside a hot mug of coffee or tea I sometimes dust them with a sprinkle of powdered sugar before serving For a brunch spread serve with fresh fruit and scrambled eggs or tuck one into a lunchbox for a sweet afternoon surprise

A Bit of Coffee Cake History
Classic coffee cake has its roots in Old World traditions and was meant to be served with a morning or afternoon cup of coffee The addition of streusel is a German touch that became popular in American baking My grandmother made a fullsized version for every family holiday and this muffin version is my nod to her kitchen
