I discovered a breakfast treat that transforms my mornings: my sour cream coffee cake. Its tender crumb paired with a cinnamon streusel topping and luscious glaze invites a delightful surprise in every bite. I absolutely love how each slice reveals layers of flavor that spark curiosity and brighten my day.

I recently whipped up my favorite sour cream coffee cake, and honestly, it turned out amazing. The cake is unbelievably moist and buttery with a kick that comes from a perfectly spiced cinnamon streusel layered right in the middle and on top.
I mixed 2 cups all-purpose flour, 1 cup granulated sugar, and 1/2 cup unsalted butter along with 2 large eggs, 1 cup sour cream, a tsp of vanilla extract, baking powder, baking soda, and a pinch of salt to create the cake base. The streusel, made from extra flour, light brown sugar, ground cinnamon, and diced cold butter, adds a sweet crunch.
I finished it off with a glaze of powdered sugar, milk, and a splash of vanilla extract that you barely help but never want to put down. If you like a little twist on your typical breakfast sweets, this sour cream coffee cake is definitely something you need to try.
Why I Like this Recipe
I love this recipe because it’s so moist and buttery that every bite feels like a little party in my mouth. My kitchen fills with the sweet smell of cinnamon as the streusel melts into the cake, and I just can’t get enough of that crunchy layer on top and in the middle. I also really enjoy how simple it is to whip up even on a busy day and, once the glaze drizzles over it while it’s still warm, the whole thing tastes perfectly balanced between sweet and rich.
When I make this cake, I always feel excited because I know I’m about to enjoy such a comforting treat. I love that the final result is not only delicious but also a bit rustic and homey, like something I’ve perfected over time even if it’s not perfect every single time.

Gives the cake its rich taste.
- Unsalted Butter: Provides richness and flavor; its fat content helps create that moist crumb.
- Eggs: Packed proteins that bind ingredients together.
They help in rising and consistency.
- Light Brown Sugar: Contributes warmth and a slight molasses taste, enhancing streusel flavor.
- Powdered Sugar: Used for a sweet glaze finish that coats cake just right.
- Baking Powder: Helps the cake rise evenly; its leavening power is reliable.

FAQ
Sour Cream Coffee Cake (cinnamon Streusel) Recipe Substitutions and Variations
- Instead of sour cream you can use full fat Greek yogurt, it works fine and keeps the cake moist.
- If you don’t have unsalted butter, try using salted butter but reduce the extra salt you add.
- You can swap all-purpose flour with whole wheat flour, though the texture might be a bit denser.
- For the streusel, use dark brown sugar instead of light brown sugar to get a richer flavor.
- If you don’t have powdered sugar for the glaze, blend granulated sugar until its a fine powder.
Pro Tips
1. When you’re creaming the butter and sugar, beat them until they’re super light and fluffy. Not overdoing it later is key cause too much mixing can make the cake tough.
2. Keep that cold butter for the streusel as cold as possible. If it softens too much, you won’t get those perfect crumbly bits on top.
3. Use a light hand when folding in the dry ingredients into the wet mix. Overmixing even a little can give you a denser cake than desired.
4. Drizzle the glaze over the cake while it’s still a bit warm. It helps the glaze soak in better, and you get that extra sweet kick once it cools down.
