Soft Cinnamon Cake Topped With Buttery Cinnamon Sugar
An incredibly tender, melt-in-your-mouth cinnamon cake topped with a thick, crackly layer of buttery cinnamon sugar.
- The reverse-creaming method coats the flour in fat first, which physically prevents water from bonding with the proteins to form tough gluten.
- Full-fat sour cream introduces lactic acid, which actively tenderizes the crumb while keeping the cake incredibly moist for days.
- Drizzling melted butter directly over the cinnamon sugar topping creates a crackly, caramelized crust that contrasts beautifully with the soft cake beneath.
I still remember the exact Tuesday morning my vintage Nordic Ware pan slipped from my flour-dusted fingers, clattering onto the linoleum and leaving a dent that I still look at every time I bake.
I was desperately trying to recreate a bakery-style cake I had eaten in a tiny coastal town, but my early attempts kept turning out like dry, sad cardboard that required a gallon of coffee just to swallow. I actually cried over a particularly dense batch that looked more like a doorstop than a dessert.
The culprit, as it turns out, was over-mixing and a complete disregard for the protein matrix of all-purpose flour. If you love the comforting warmth of cinnamon but want something faster, you might also enjoy my Banana Cinnamon Oats for a quick morning fix.
By switching to a reverse-creaming method—where you coat the flour in butter first—we limit gluten development. This technique is similar to how we handle the dough for Cinnamon Sugar Cruffins to keep them incredibly tender.
Trust me on this one.
Soft Cinnamon Cake Topped With Buttery Cinnamon Sugar
Ingredients
- 200g all-purpose flour
- 150g granulated sugar
- 1.5 tsp baking powder
- 0.5 tsp baking soda
- 0.5 tsp Diamond Crystal kosher salt
- 115g unsalted butter, softened
- 120g full-fat sour cream
- 2 large eggs, room temperature
- 1 tsp vanilla extract
- 100g light brown sugar (for the topping)
- 2 tbsp ground cinnamon (for the topping)
- 45g unsalted butter, melted (for the topping)
Directions
- Preheat your oven to 350°F (175°C) and grease an 8-inch square baking pan with butter or non-stick spray.
- In the bowl of a stand mixer fitted with the paddle attachment, combine the flour, granulated sugar, baking powder, baking soda, and kosher salt on low speed.
- Add the softened butter and sour cream to the dry ingredients, mixing on low until the flour is completely coated and the mixture looks like damp sand.
- In a small bowl, whisk the eggs and vanilla extract together, then slowly stream them into the mixer, beating on medium-low until a thick, smooth batter forms.
- Spread the batter evenly into your prepared baking pan using an offset spatula to smooth the surface.
- In a separate bowl, mix the brown sugar and ground cinnamon, then sprinkle this mixture evenly over the top of the cake batter.
- Drizzle the melted butter carefully over the cinnamon sugar layer, covering as much of the surface as possible.
- Bake for 30 to 35 minutes, or until a toothpick inserted into the center of the cake comes out clean.
Notes
- Salt Conversion: We use Diamond Crystal kosher salt. If you are using fine table salt, cut the measurement in half (use 0.25 tsp) to avoid an overly salty cake.
- The Science of Sour Cream: The lactic acid in full-fat sour cream weakens the gluten bonds in the flour, which is the secret to achieving that ultra-soft, bakery-style crumb.
- Workflow Warning: Keep a close eye on your oven around the 30-minute mark; the high sugar content in the topping can scorch quickly if your oven runs slightly hot.
- Storage Behavior: This cake actually tastes better on day two because the buttery cinnamon topping slowly sinks into the crumb, making it even more moist.
Serving Suggestions
This cake is absolutely spectacular when served warm, but you can easily elevate it for a weekend brunch or a cozy afternoon tea.
- A generous dollop of unsweetened whipped cream to balance the sweet topping
- A scoop of high-quality vanilla bean ice cream for a decadent dessert
- A warm cup of black coffee or a spiced chai latte
- Fresh raspberries or sliced strawberries on the side to add a bright, acidic contrast
Storage and Reheating
Store any leftover cake in an airtight container at room temperature for up to three days. Do not refrigerate it, as the cold air will dry out the delicate crumb matrix faster than you can say "stale."
If you want to keep it longer, wrap individual slices tightly in plastic wrap and freeze them for up to two months.
To reheat, skip the microwave.
Instead, pop a slice into a 300°F (150°C) toaster oven for about five minutes. This revives the butter in the topping, making it beautifully crisp and fragrant all over again.
It will taste exactly like it did the moment it first slid out of your oven.
Ingredient Substitutes
If you find yourself missing an ingredient, here are the tested swaps that won't ruin your bake.
- Sour Cream: You can swap this with equal parts full-fat Greek yogurt, though the crumb will be slightly less rich.
- All-Purpose Flour: A 1:1 gluten-free baking blend works beautifully here due to the high fat content of the batter.
- Brown Sugar: Coconut sugar can be used for the topping, though it won't melt into quite the same caramel-like crust.
I hope this cake brings a little bit of cozy magic to your kitchen this week. Let me know if you manage to let it cool completely before slicing—I certainly never do.
