Based on one of my grandmother’s classic recipes, this moist and tender sour cream chocolate chip coffee cake is studded with chocolate chips and features a crunchy cinnamon sugar topping that’s a delight to behold (and even more so to eat!)
Grandma’s famous coffee cake is back… now with chocolate chips! Sure the apple version is good and all, but let’s be honest with ourselves here: chocolate chips are so much better.
The cake itself is moist and tender, slightly more dense and rustic-crumbed than a standard white layer cake. It falls somewhere in between the texture of a cake and a muffin. And we’ll go ahead and go all in on that muffin influence as excuse to eat this cake for breakfast (that IS why they call it coffee cake, after all).
Whoever decided to call it coffee cake was a freaking genius I tell you. One, because cake and coffee were clearly meant to be enjoyed together, and two, because cake for breakfast is always a good idea.
Knowing my grandma and her enormous sweet tooth, I’m sure she would have approved of such behavior (and would likely join in on the fun).
But the best part of this coffee cake, aside from the chocolate chips of course, is the crispy sugar topping. There’s really no need for a complicated crumb here (or anywhere, really), as simply sprinkling and swirling some cinnamon sugar inside and on top of the cake batter results in a delicately crispy topping that’s simply divine. With a few extra chocolate chips and some crispy cacao nibs, it’s practically perfect in every way.
I opted out of the nuts this time (but my all means, go nuts if you like!) and sprinkled the top with a few cacao nibs for some added crunch.
This is one of those recipes—not unlike my shortbread cookie bars or soft amaretti cookies—that serves as a base for myriad flavor variations. Swap out the chocolate chips or the apples for… well, anything, really. Blueberries maybe (with a touch of lemon zest?) Chopped pecans or dried tart cherries maybe? A pinch or two of instant espresso powder (then would it be coffee coffee cake?)
The sour cream base is as flexible as it is delicious. Let your tastebuds (and your imagination) run wild!
I baked the cake this time in an 8-inch tube pan, which took a bit longer than the deep 9-inch cake pan I used previously (thicker cake = longer bake). Both pans have removable bottoms, which makes for much easier removal. A springform pan would work, although I often find the sides of these too thin to conduct heat very evenly (so your edges will get browner before the center is fully cooked).
While the recipe is quite flexible in terms of baking pan size, just know that the bake time might need to be adjusted (a 9-inch square pan, for example, has a larger total volume and would produce a thinner cake, so you’d want to bake it for less time). Start checking it after 30 to 35 minutes or so (when the top is no longer visibly jiggly) and go from there. You’ll know it’s done when the top is golden and crispy and a toothpick inserted near the center comes out clean or with just a few moist crumbs attached.
Whatever pan you use, just be sure you don’t fill it over 2/3 of the way full, lest your batter overflow in the oven (and trust me, cake overflow is no fun to clean up). It’s slightly too much batter, for example, than a standard 9-inch cake pan can take. So unless you have a 3-inch deep pan, you’d best leave some of the batter out (or, better yet, make a muffin or two – you won’t regret it!)
