We’re talking about the legendary Chocolate Crumble Cake, a masterpiece that’s equal parts simple to bake and impossible to resist.

This isn’t just any cake; it’s a symphony of textures and flavors. It’s the kind of dessert that whispers sweet nothings of warm kitchens and cozy nights, the kind that begs to be shared with loved ones and devoured with melty ice cream on the side. 

But before you get carried away picturing oozing chocolate lava and buttery crumble mountains, let’s delve into the fascinating world of this crumbly crown jewel.

A History of Chocolate Crumble Cake:

While the exact origin of this glorious creation remains shrouded in baking lore, whispers trace its roots back to post-war America. Imagine kitchens bustling with resourceful homemakers, whipping up comforting treats with humble ingredients. 

Flour, sugar, cocoa, and a touch of ingenuity combined to create this masterpiece, born from the desire for both decadent indulgence and frugal satisfaction.

The Crumble Codex:

Now, onto the nitty-gritty: how to make the best Chocolate Crumble Cake ever. Picture this: a moist, fudgy chocolate cake base studded with pockets of melty chocolate chips. 

On top, a golden, buttery crumble that crumbles just so, offering a textural counterpoint to the velvety cake below. Sounds pretty heavenly, right?

The magic lies in the simplicity of its construction. It’s like a baking chemistry experiment gone gloriously right. Flour, cocoa, leavening agents, and a touch of magic (ahem, sugar) dance together to form the cake batter. 

Meanwhile, that golden crumble topping? It’s just flour, butter, and sugar coaxed into a buttery, crumble-tastic submission.

Conquering the Crumble:

Here’s where the real fun begins. Preheat your oven, gather your ingredients, and channel your inner baking wizard. Whisk, stir, fold, and crumble your way to chocolatey bliss. Pro tip: don’t overmix the batter, a few gentle folds are all it takes to maintain that light, fluffy texture. 

And when it comes to the crumble, embrace the chunkiness! Those larger clumps are what make each bite of this chocolate crumble cake an explosion of buttery delight.

Now comes the moment of truth: the oven. Watch as your kitchen transforms into a chocolate-scented haven. When that golden hue peeks through the edges, and the aroma intensifies, you know it’s time. 

Let it cool slightly (patience is a virtue, especially when molten chocolate is involved!), then unleash your inner cake ninja and slice that bad boy open.

Crumble Coronation:

And there it is, in all its crumbly, fudgy, chocolatey glory. But wait, the masterpiece isn’t complete yet! Dust it with powdered sugar for a touch of elegance, drizzle it with warm ganache for extra decadence, or scoop a dollop of vanilla ice cream on top for the ultimate crumble coronation.

For the crumb topping:

  • 2 ½ cups 312 g all-purpose flour
  • 1 cup 200 g granulated sugar
  • ½ cup 35 g unsweetened cocoa powder (use a mix of natural and Dutch process cocoa powder for the best flavor)
  • 1 teaspoon 4 g salt
  • 1 cup 226 g unsalted butter, melted

For the cake:

  • 1 ¾ cups 227 g all-purpose flour
  • 2 cups 400 g granulated sugar
  • ¾ cup 85 g unsweetened cocoa powder (use a mix of natural and Dutch process cocoa powder for the best flavor)
  • 2 teaspoons 10 g baking soda
  • 1 teaspoon 4 g baking powder
  • 1 teaspoon 4 g salt
  • 1 cup 240 g sour cream
  • cup 80 ml vegetable oil
  • 2 large eggs
  • 2 teaspoons 10 ml vanilla extract
  • ½ cup 120 ml hot brewed coffee (you can also use hot water)

For dusting the finished cake:

  • Powdered sugar


  • Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Spray a 9×13 inch baking pan with nonstick baking spray.
  • Make the crumb topping: In a medium bowl, whisk together the flour, sugar, cocoa powder, and salt. Then, drizzle in the melted butter and stir until everything is well combined. The mixture will seem gooey at first, but it will dry out as you mix it. Set the crumb topping aside.
  • Make the cake: In a large bowl, whisk together the dry ingredients (flour, sugar, cocoa powder, baking soda, baking powder, and salt). Set aside.
  • In a medium bowl, whisk together the wet ingredients (sour cream, oil, eggs, vanilla extract, and hot coffee). Then, pour the wet ingredients into the dry ingredients and mix until everything is just combined. Don’t overmix!
  • Pour the batter into your prepared baking pan and smooth out the surface.
  • Sprinkle the crumb topping evenly over the batter, making sure to get it all the way to the edges of the pan. Don’t mound the crumbs in the center.
  • Bake the cake in the center rack of your preheated oven for 35-45 minutes, or until a toothpick inserted into the center comes out with fudgy crumbs (the cake is done when the center is no longer wobbly).
  • Let the cake cool for about 10-15 minutes before generously dusting it with powdered sugar.


  • You can substitute yogurt for the sour cream. Just make sure to use plain, unflavored yogurt.
  • Melted butter can be substituted for oil in cake recipes. The melted butter can be substituted in the same quantity as the oil called for in the recipe.
  • You can use all-natural cocoa powder if you don’t have Dutch-processed cocoa powder. However, the cake will have a slightly less intense chocolate flavor.
