Chocolate Chip Coffee Cake

If you love a soft, buttery coffee cake with a thick cinnamon crumb, this chocolate chip coffee cake is going to become your new weekend favorite. It checks all the boxes: tender sour cream cake, a gooey ribbon of chocolate and cinnamon running through the center, and a crunchy streusel on top.

 

I’ve made a lot of crumb cakes over the years, like my apple crumb cake or blueberry crumb cake. It’s one of those bakes I return to again and again—soft, buttery, piled high with streusel, and the kind of thing I end up snacking on long before the guests arrive. So when the idea for this twist hit me, I knew I had to try it: the same tender, melt-in-your-mouth texture I love but with a fun, new flavor spin that makes the whole recipe feel brand new again.

This version stays true to everything I adore about the original—simple ingredients, easy mixing, and that signature bakery-style crumb on top. It’s the kind of recipe you can pull together without fuss, and it rewards you every single time.

This recipe is also wonderfully forgiving and beginner-friendly. You don’t need fancy equipment—just a hand mixer, a whisk, and a mixing bowl. The sour cream keeps the cake incredibly moist (even days later), the mini chocolate chips melt into perfect little pockets of sweetness, and the crumb topping gives you that classic coffee-shop texture without being overly sweet.

Ingredients You’ll Need

• Brown sugar: Light brown sugar gives the crumb that deep, caramel-y flavor. Make sure it’s packed and not dried out—old brown sugar won’t hold the crumb together. If you run out, try my homemade brown sugar.
• Cinnamon
• Butter: You’ll need melted butter for the topping and softened butter for the cake. For the softened butter, pull it out 1–2 hours ahead; it should give slightly when pressed but not feel greasy.
• All-purpose flour: Measure using the spoon-and-level method so the cake stays soft, not dense. Too much flour can cause the streusel to get dry and the cake to bake up heavy.
• Mini chocolate chips: Regular chips work, but minis give you chocolate in every bite.
• Leaveners: Baking powder and baking soda help the cake rise. Double-check that they’re fresh—old leaveners lead to cakes that sink in the middle or bake up dense.
• Sour cream: Full-fat is best. You can swap in full-fat Greek yogurt if that’s what you have, but sour cream gives a richer flavor.
• Eggs: The eggs should be room temperature so they incorporate easily and create a smoother batter.
• Vanilla

How to Make Chocolate Chip Coffee Cake

Make the crumb topping

Start by preheating your oven to 350°F and greasing a 9×9 square baking pan.

To make the crumb topping, whisk together the brown sugar, cinnamon, and salt.

Then pour in the melted butter and stir until everything is evenly moistened.

Add the flour and use a fork to toss it all together. You’re looking for soft, clumpy crumbs—not a dough and not a powder. If it looks too floury, keep mixing; if it looks too wet, sprinkle in an extra spoonful of flour.

Make the cake batter

For the cake, whisk the flour, baking powder, baking soda, and salt together in a small bowl. Having this ready helps prevent overmixing once you start adding it to the batter and even distribution of the leavening agents.

I like to stir in the chocolate chips at this point. By coating them in the dry ingredients it helps the chips from sinking to the bottom of the cake.

In a larger bowl, cream the softened butter with the white and brown sugars. This takes about 2 minutes and the mixture should look lighter in color and fluffier in texture. If it’s sticking to the sides of the bowl, stop and scrape everything down. This step is key—properly creamed butter creates a finer crumb and prevents the cake from coming out dense.

I like to use my stand mixer fitted with the paddle attachment but a hand mixer also works. You will just need to cream it longer.

Add the eggs one at a time, mixing well after each addition, then blend in the vanilla. The batter may look slightly curdled after the eggs, but it will come together once the flour is added.

Now it’s time to alternate the dry ingredients with the sour cream. This method helps keep from overmixing which helps to create a tender cake. Start with a portion of the dry mixture, mix just until combined, then add some sour cream. Repeat, ending with the dry mixture. Avoid overmixing—stop as soon as the flour disappears.

Assemble the coffee cake

Spread half the batter into your prepared pan. This batter is thick, so use an offset spatula or the back of a spoon to nudge it into an even layer. Sprinkle half the crumb topping over the batter, making sure it reaches the edges—this creates that delicious middle ribbon.

Add the rest of the batter, smoothing it as best you can, then finish with the remaining crumb topping.

Bake the coffee cake until the top is golden brown and a toothpick inserted into the center comes out clean. Every oven runs a little differently, so start checking around the 40-minute mark. If the middle sinks or stays gooey, it likely needed just a bit more time—coffee cakes can look done before they are done, especially with a thick streusel on top.

Let the cake cool in the pan before slicing. The crumb sets as it cools, preventing it from crumbling apart.

You can always dust the top with powdered sugar before serving for a little sweetness and a pretty presentation.

Storage Tips

This cake stays incredibly moist thanks to the sour cream.

• Store tightly wrapped at room temperature for several days.
• Refrigerate if you want it to last up to a week.
• Freeze individual slices for up to three months—warm them in the microwave for that fresh-baked texture.
