Chocolate Coffee Cake

If you love that deep chocolate flavor with a subtle coffee kick, this chocolate coffee cake is one of those recipes you’ll keep coming back to. It’s soft, slightly crumbly on top, and has that bakery-style richness without being overly sweet. I’ve made this more times than I can count, and honestly, it never lasts more than a day in the kitchen.

This is not just a dessert cake, it works beautifully as a breakfast treat or afternoon snack too.

Why This Recipe Works

• The coffee enhances the chocolate flavor (you don’t really taste coffee strongly)
• Super moist texture thanks to sour cream
• Simple pantry ingredients, nothing fancy needed
• Works great as a make-ahead cake
• That crumb topping gives a nice little crunch (which I personally love)

Ingredients

For the Cake Batter:

• 2 cups all-purpose flour
• 1 cup granulated sugar
• 1/2 cup brown sugar (packed)
• 3/4 cup unsweetened cocoa powder
• 1 1/2 tsp baking powder
• 1/2 tsp baking soda
• 1/2 tsp salt
• 2 large eggs (room temp works better)
• 1 cup sour cream
• 1/2 cup whole milk
• 1/2 cup vegetable oil
• 1 tbsp vanilla extract
• 3/4 cup hot brewed coffee (not boiling, just hot)

For the Crumb Topping:

• 1/2 cup brown sugar
• 1/3 cup all-purpose flour
• 1 tsp cinnamon
• 1/4 cup unsalted butter (melted)

Optional Chocolate Drizzle:

• 1/2 cup semi-sweet chocolate chips
• 2 tbsp heavy cream

Ingredient Notes

• Coffee: Fresh brewed is best. Instant coffee works too but flavor slightly differ.
• Cocoa Powder: Use good quality unsweetened cocoa for richer taste.
• Sour Cream: This is key for moisture. Don’t skip it, seriously.
• Oil vs Butter: Oil keeps it softer longer compared to butter.

Step-by-Step Instructions

Step 1

Preheat your oven to 350°F. Grease a 9×9 inch baking pan or line it with parchment paper.

Step 2

In a large bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.

Step 3

In another bowl, mix granulated sugar, brown sugar, eggs, sour cream, milk, oil, and vanilla extract.

Step 4

Slowly add the wet mixture into the dry ingredients. Don’t overmix, just combine till smooth-ish.

Step 5

Pour in the hot coffee gradually and mix. The batter will look thin, that’s totally normal.

Step 6

Prepare the crumb topping by mixing brown sugar, flour, cinnamon, and melted butter until crumbly.

Step 7

Pour the batter into the prepared pan evenly.

Step 8

Sprinkle the crumb topping all over the batter. Try to cover most of the surface.

Step 9

Bake for 32–38 minutes or until a toothpick inserted in center comes out mostly clean (few crumbs ok).

Step 10

Let it cool for at least 15–20 minutes before cutting. It’s hard to wait but worth it.

Step 11 (Optional)

Melt chocolate chips with heavy cream and drizzle over the cake. This step is optional but I always do it.

My Personal Tips While Making This

• Don’t skip the coffee even if you think you dont like it, it really boosts chocolate flavor
• Batter looks too runny? It’s fine, trust the process
• I once overbaked it by 5 minutes and it got slightly dry, so keep an eye last few minutes
• Next day taste is even better somehow, flavors settle nicely
