A unique coffee cake
We're used to coffee cakes being vanilla cakes with streusel topping.
If you google chocolate coffee cake, you hardly find any. I mean a coffee cake that is chocolate-flavored. With sour cream in the batter and streusel or crumble.
All recipes are traditional chocolate cakes that use coffee as a flavor enhancer or complement it. Like the chocolate ganache bundt cake.
So, I had to come up with one. It was imperative. And top it with chocolate chips, so it was clear what it was about.
Originally, I added chopped pistachios to the streusel. It makes for a great cake, but not an all-chocolate coffee cake like I had in mind.
What is a coffee cake?
They are dense and rich cakes with a streusel in the middle, as a topping, or both. They do not have coffee but are made to accompany it, hence the name.
They are sweet, perfect for brunch, and can be adapted to most cake flavors, like the pumpkin coffee cake and apple coffee cake, both popular in this blog.
This recipe for chocolate coffee cake has a chocolate streusel and is a great snacking cake to serve at brunch, plain or with a simple glaze.
Ingredient list
- Chocolate chips: use your favorite semisweet chip.
- Cocoa powder: always use unsweetened.
- Sour cream: the regular type, full-fat sour cream cheese is used for richness and creaminess.
- White granulated sugar.
- Brown sugar: light or dark.
- Eggs: fresh, large.
- Vanilla extract.
- Salt.
- Baking powder and baking soda: make sure they aren't expired.
- Ground cinnamon.
Quantities are listed in the recipe card towards the end of this post. The Ingredients page has more details and lists the brands we use.
Variations & substitutions
- Nuts: instead of, or in addition to, the chocolate chips topping. I used to make it with pistachios years ago. Hazelnuts also pair very well.
- Milk chocolate chips: substitute for the semisweet in the batter for a sweeter cake.
- Chocolate ganache icing: drizzle it on top instead of the powdered sugar glaze for an over-the-top chocolate dessert.
How to make chocolate crumb cake
Streusel topping
It's very easy to make and can be made ahead and kept refrigerated for a week in a covered container.
The dry ingredients are combined in a medium bowl.
Cold butter pieces are added and mixed until clumpy with a fork. Refrigerate it while making the chocolate batter.
Chocolate cake:
It's a classic butter cake with cocoa powder and has chocolate chips in the batter.
Beat sugars and butter for a few minutes, then add the eggs and vanilla, integrating well. Using an electric mixer is the best option.
The sour cream is added alternating with the dry ingredients. At this point, beat to integrate well but don't overdo it, or the cake will not be as fluffy.
Add the semisweet chocolate chips and stir to combine. You can use the electric mixer at low speed or a rubber spatula.
Transfer the cake batter to the prepared pan and smooth out the top.
Paula's Tip
After incorporating flour into a cake batter, you don't want to develop gluten, as it will toughen the baked cake. So mix *just* until it's all well incorporated, but don't overbeat. Also, I like to end mixing with a silicone spatula to ensure the ingredients are fully integrated.
For the chocolate crumb topping, mix chocolate chips with the streusel and sprinkle on top of the cake batter.
Bake as directed, removing it from the oven when a cake tester or toothpick comes out clean. The topping will have sunk into the batter in places.
Powdered sugar glaze
I am a huge fan of simple glazes or icings to drizzle over coffee cakes, which will enhance the sweetness.
- Cooled cake: it's essential before drizzling the glaze. Otherwise, it will thin out due to the heat.
- Make it ahead: refrigerate it in an airtight container or tightly covered bowl. A thin shell will probably form on the top. Simply beat it again before using it. If needed, add another teaspoon or two of liquid.
- Liquid: there are several you can use besides milk or cream. Coffee liqueur, rum or bourbon, orange juice, chocolate milk, they can all work.
Kitchen notes
- Organization: read the recipe first and ensure you have ingredients at the correct temperature, equipment, and enough workspace. This will make the process so much easier.
- Baking time: consider that all ovens and pans are different, even if they look similar. The baking time in my recipes is as accurate as it can be, but it might take you more or less time. You can use a thermometer(like the OXO oven thermometer) to check that your oven is at the right temperature. I recommend you keep track of how your oven works and what tiny details you might need to adjust.
- Brown sugar: gives a slight caramel undertone that pairs very well with chocolate and adds moisture.
- Sour cream: is a must when making this type of cake, and you'll see why with each rich and dense (but not heavy) bite. It also adds moisture and structure, holding the streusel in place better.
- Storage: it keeps well for 2-3 days at room temperature and in the fridge for 5-7 days, well covered or wrapped to prevent dryness. Or freeze it for up to a month.
- Serving it: glazed at room temperature is the best option. Served with fresh berries is also a good alternative, especially for a brunch table.

What a lovely and unique cake, Paula! I am already dreading winter here. Maybe it won't come 🙂
Marissa | Pinch and Swirl says
I agree. There are few things more comforting than baking a cake, especially when it's cold out. There's something healing about the process and then the heavenly scent that fills your home.
I love the pistachios and how deep dark the cake is. Lovely.
Silvia says
Pistachio & cofee ... hum, Paula !
Angie Schneider says
A fantastic coffee cake, Paula. I love the combo of chocolate and coffee.
Stacy says
I wouldn't change a thing, Paula! I like the deep dark color. It seems even more chocolatey somehow. Like how the brown M&Ms taste more chocolatey than the colored one. Or is that just me?
I know what you mean about winter time. I love to bake bread and cakes - anything that turns that oven on. And the whole house smells sweet. Stay warm, my friend!
Shu Han says

Deb says
Chocolate and pistachios are a magnificent pairing! Although we are in the midst of summer, our coastal fog demands warm jackets and a mug of steaming coffee or tea. And a slice of the Chocolate Pistachio Cake would be divine!
