This guide covers everything you need to bake this coffee cake successfully: a fully tested recipe, the technique behind achieving the ideal cinnamon swirl and streusel texture, step-by-step instructions, troubleshooting tips, delicious variations, storage advice, and answers to the most frequently asked questions about this recipe.
What Is a “Coffee Cake,” Exactly?
Despite the name, coffee cake doesn’t actually contain coffee; rather, it’s a cake specifically designed to be enjoyed alongside a cup of coffee, typically for breakfast or as an afternoon treat. Unlike a layered celebration cake, coffee cakes are usually baked in a single pan, are less sweet than a dessert cake, and often feature a streusel or crumb topping rather than frosting, making them just as suitable for breakfast as they are for dessert.
Why This Recipe Works
- A moist, tender crumb thanks to sour cream in the batter.
- A distinct cinnamon-sugar swirl running through the center of the cake, not just on top.
- A generous streusel topping with the perfect balance of crunch and buttery flavor.
- Simple pantry staple ingredients with no unusual or hard-to-find items.
- Keeps beautifully for several days, making it ideal for make-ahead breakfasts.
Ingredients You’ll Need
This recipe makes one 23cm (9-inch) square or round cake, serving 9 to 12 people.
For the Streusel Topping
- 100g (½ cup) packed brown sugar
- 100g (¾ cup) all-purpose flour
- 1½ teaspoons ground cinnamon
- Pinch of salt
- 75g (⅓ cup) cold butter, cubed – Keeping the butter cold and cutting it in (rather than melting it) is what creates that classic crumbly streusel texture.
For the Cinnamon Swirl Filling
- 75g (⅓ cup) packed brown sugar
- 1½ tablespoons ground cinnamon
For the Cake Batter
- 280g (2¼ cups) all-purpose flour
- 1½ teaspoons baking powder
- ½ teaspoon bicarbonate of soda
- ¼ teaspoon fine salt
- 115g (½ cup) softened butter
- 150g (¾ cup) white sugar
- 2 large eggs, at room temperature
- 2 teaspoons vanilla extract
- 240g (1 cup) sour cream, at room temperature – The key to this cake’s signature moist, tender texture.
Optional Glaze
- 75g (½ cup) icing sugar, sifted
- 1 to 2 tablespoons milk
- ¼ teaspoon vanilla extract
Equipment You’ll Need
- 23cm (9-inch) square or round baking pan
- Mixing bowls
- Electric hand mixer or stand mixer
- Pastry cutter or fork, for the streusel
- Toothpick or skewer, for testing doneness
- Wire cooling rack
Step-by-Step Instructions
Step 1: Preheat and Prepare the Pan
Preheat your oven to 175°C (350°F). Grease a 23cm square or round baking pan and line the bottom with baking paper for easy removal.
Step 2: Make the Streusel Topping
In a bowl, combine the brown sugar, flour, cinnamon, and salt. Add the cold, cubed butter and use a pastry cutter, fork, or your fingertips to work it into the dry ingredients until the mixture forms coarse, pea-sized crumbs. Refrigerate the streusel while you prepare the rest of the cake; keeping it cold helps it hold its shape and stay crumbly rather than melting flat during baking.
Step 3: Make the Cinnamon Swirl Filling
In a small bowl, mix together the brown sugar and cinnamon for the swirl filling. Set aside.
Step 4: Combine the Dry Ingredients for the Cake
In a bowl, whisk together the flour, baking powder, bicarbonate of soda, and salt.
Step 5: Cream the Butter and Sugar
In a large mixing bowl, beat the softened butter and sugar together until pale and fluffy, about 3 minutes. This step incorporates air into the batter, contributing to a lighter final texture.
Step 6: Add the Eggs and Vanilla
Beat in the eggs one at a time, mixing well after each addition, then mix in the vanilla extract.
Step 7: Alternate Adding Dry Ingredients and Sour Cream
With the mixer on low speed, add about a third of the dry ingredients, followed by half of the sour cream, then another third of the dry ingredients, the remaining sour cream, and finish with the last of the dry ingredients. Mix just until combined after each addition to avoid overworking the gluten, which would result in a denser cake.
Step 8: Layer the Batter and Cinnamon Swirl
Spread about two-thirds of the batter into the prepared pan in an even layer. Sprinkle the cinnamon-sugar swirl mixture evenly over the top. Carefully dollop and spread the remaining batter over the cinnamon layer, smoothing it out as best you can; it’s fine if a little of the cinnamon layer peeks through.
Step 9: Add the Streusel Topping
Remove the streusel from the fridge and sprinkle it evenly over the top of the batter, covering the entire surface.
Step 10: Bake
Bake for 40 to 50 minutes, or until a skewer inserted into the center comes out clean or with just a few moist crumbs attached, and the streusel topping is golden brown. If the top is browning too quickly before the center is done, loosely tent the pan with foil for the remaining bake time.
Step 11: Cool the Cake
Let the cake cool in the pan for at least 20 minutes before slicing, as the interior needs time to fully set. For clean slices, allow it to cool further, or serve slightly warm for a softer texture.
Step 12: Add the Glaze (Optional)
If using the glaze, whisk together the icing sugar, milk, and vanilla extract until smooth, and drizzle it over the top of the cooled or slightly warm cake before slicing and serving.
Expert Tips for the Best Coffee Cake
- Keep the streusel butter cold: This is the key to a crumbly, textured topping rather than one that melts flat and hard.
- Don’t overmix the batter: Mixing just until the flour disappears keeps the crumb light and tender rather than dense.
- Use room temperature ingredients: Cold eggs or sour cream can cause the batter to look curdled and won’t incorporate as smoothly.
- Layer the swirl carefully: Spreading the top layer of batter gently over the cinnamon filling helps keep the swirl distinct rather than blending it entirely into the cake.
- Let it cool before slicing: Cutting too early can cause the cake to fall apart, since the crumb is still setting as it cools.
Delicious Variations to Try
- Apple Cinnamon Coffee Cake: Fold 1 cup of finely diced apple into the batter along with the dry ingredients for extra moisture and flavor.
- Pecan Streusel Coffee Cake: Add 50g of chopped pecans to the streusel mixture for extra crunch and a nutty flavor.
- Blueberry Coffee Cake: Fold 1 cup of fresh or frozen blueberries into the batter for a fruity twist.
- Maple Glaze Version: Replace the vanilla in the glaze with maple extract, or swap some of the milk for maple syrup.
- Mini Coffee Cakes: Bake the batter in a muffin tin with a smaller portion of streusel on top, reducing the baking time to about 20 minutes.
Storage Instructions
- Room temperature: Store in an airtight container for up to 3 days.
- Refrigeration: Store in an airtight container for up to a week; bring to room temperature or warm slightly before serving.
- Freezing: Wrap the unglazed, cooled cake tightly in plastic wrap and foil, then freeze for up to 3 months. Thaw at room temperature and glaze just before serving, if using.

Frequently Asked Questions
Why did my streusel melt flat instead of staying crumbly?
This usually happens when the butter in the streusel was too warm or soft when mixed in. Keep the butter cold and, if needed, chill the finished streusel mixture again briefly before adding it to the cake.
Can I make this cake ahead of time?
Yes, this cake actually keeps very well and tastes just as good, if not better, the next day. Store it covered at room temperature and glaze, if using, just before serving.
Why did the cinnamon swirl sink to the bottom?
This can happen if the batter layer underneath the swirl was too thin or the swirl mixture was too heavy. Make sure to spread a solid layer of batter first before adding the cinnamon-sugar filling.
Can I use Greek yogurt instead of sour cream?
Yes, full-fat plain Greek yogurt makes a good substitute for sour cream in this recipe, providing a similar moist texture and tang.
Why is my cake dense instead of light?
Dense cake is usually caused by overmixing the batter after the flour is added, or by not creaming the butter and sugar long enough at the start.
Can I bake this in a bundt pan instead?
Yes, though you’ll need to layer the cinnamon swirl carefully throughout the batter rather than in a single layer, and streusel toppings don’t work as well in bundt pans since they’re inverted after baking; a simple glaze is a better finishing option for that shape.
Final Thoughts
Cinnamon Streusel Coffee Cake brings together everything comforting about a classic bake: a soft, buttery crumb, a warm cinnamon swirl, and a crunchy, sweet topping that makes every bite satisfying.
