I am absolutely obsessed with my cinnamon coffee marble loaf recipe, but I knew I wanted to create a round cake version of it for special occasions and cozy gatherings. When I started testing it, I felt like it was missing that little extra something on top. At first, I tested it with just a handful of chocolate chips scattered over the batter, but then I thought—why stop there when I love crumble topping so much?

So, I developed a thick, chocolate chip crumble topping, scattered it generously over the coffee-cocoa and cinnamon marbled batter, and baked it up. The result? It is basically a brookie (brownie-cookie!) in cake form! The brown butter and cream cheese in the batter make it melt-in-your-mouth tender, while the chocolate chip crumble gives it the best buttery crunch. It is so, so good!

Why You’ll Love This Recipe

• Inspired by My Favorite Marble Loaf: Takes those loved coffee and cinnamon marble flavors and elevates them into a round cake format.
• Brookie in Cake Form: Combines rich chocolate-coffee brownie notes, warm cinnamon cake, and a buttery chocolate chip cookie crumble topping.
• Nutty Brown Butter Base: Nutty browned butter adds incredible depth and richness to the tender cake crumb.
• Tangy Cream Cheese Texture: Softened cream cheese folded into the batter keeps the crumb meltingly soft and velvety moist for days.
• Double Flavor Swirl: A striking, marbled contrast of deep coffee-cocoa and fragrant ground cinnamon in every slice.

Ingredients

For the Chocolate Chip Crumb Topping

• 125g all-purpose flour (~1 cup)
• 65g granulated sugar (~⅓ cup)
• 75g brown sugar, light or dark (~⅓ cup packed)
• 115g butter, salted or unsalted, melted (8 tbsp / 1 stick)
• 1 ½ tsp vanilla extract
• Pinch of salt
• 130g dark or milk chocolate chips (mini chocolate chips work best!)

For the Base Cake Batter

• 250g unsalted butter (for browning)
• 200g granulated sugar
• 80g brown sugar, light or dark
• 4 large eggs, at room temperature
• 2 ¾ tsp vanilla extract
• 225g cream cheese, at room temperature
• 310g all-purpose flour
• ¾ tsp baking soda
• ¾ tsp baking powder

For the Flavor Swirls

• Coffee mixture: 5 ½ tsp instant coffee dissolved in 2 ¾ tbsp hot water
• 35g unsweetened cocoa powder
• 1.4 tbsp (~13g) ground cinnamon

Instructions

1. Make the Chocolate Chip Crumb Topping

In a medium bowl, whisk together the all-purpose flour, granulated sugar, brown sugar, and a pinch of salt.

Pour in the melted butter and vanilla extract. Stir with a fork or spatula until thick, coarse clumps form. Fold in the mini chocolate chips. Place the bowl in the refrigerator to chill while you prepare the cake batter.

(Chilling the crumble prevents it from melting into the batter while baking!)

2. Brown the Butter

In a saucepan, melt the 250g of unsalted butter over medium heat. Stir frequently as it foams up. Continue cooking for about 5 to 8 minutes until the milk solids turn a golden amber color and give off a rich, nutty aroma.

Immediately pour the browned butter into a large mixing bowl and let it cool for 10 to 15 minutes until warm to the touch, but not boiling hot.

3. Prepare the Base Batter

Preheat your oven to 180°C (350°F) conventional or 160°C (325°F) fan. Grease a 23 cm (9-inch) round cake pan and line the bottom with a circle of parchment paper.

Add the granulated sugar and brown sugar to the warm browned butter and whisk until combined. Add the eggs one at a time, whisking thoroughly after each addition. Whisk in the vanilla extract and softened room-temperature cream cheese until smooth and creamy.

Sift in the flour, baking soda, and baking powder. Gently fold with a spatula just until combined and no dry flour streaks remain.

4. Divide and Flavor the Batters

Divide the cake batter evenly into two separate bowls.

• Coffee-Cocoa Batter: Into the first bowl, fold in the 35g cocoa powder and the dissolved instant coffee mixture until completely smooth and uniform.
• Cinnamon Batter: Into the second bowl, fold in the 1.4 tbsp ground cinnamon until fully incorporated.

5. Assemble, Swirl & Top

Alternate large scoops/dollops of the coffee-cocoa batter and cinnamon batter into your prepared 23 cm round cake pan.

Take a butter knife or skewer and gently draw 2 to 3 figure-eight swirls through the batter to create a marbled effect. (Do not over-mix, or the distinct colors and flavors will bleed together!)

Take the chilled crumb topping out of the fridge and break it into rustic clusters. Scatter the chocolate chip crumble evenly over the entire top of the cake.

6. Bake and Cool

Bake at 180°C (350°F) for 45 to 55 minutes.

Check at 35 minutes: If the chocolate chip crumb topping is turning a deep golden brown, loosely tent a sheet of aluminum foil over the top of the cake pan for the remaining bake time to prevent over-browning.

The cake is done when a wooden skewer inserted into the center comes out clean or with a few moist crumbs attached. Allow the cake to cool in the pan on a wire rack for 15 to 20 minutes, then run a butter knife around the edges to release before transferring to a serving plate.

The Evolution: From Loaf to Brookie Crumble Cake

Converting my cinnamon coffee marble loaf into a round cake gave me the perfect surface area for a crunch topping. Moving from plain chocolate chips to a full-on chocolate chip crumb topping transformed this from a simple coffee cake into a “brookie” cake! You get the dense, fudgy chocolate-coffee notes reminiscent of a brownie, layered with warm cinnamon spice and topped with a buttery chocolate chip cookie crumble.

Why Brown Butter & Cream Cheese Matter

Browning the butter caramelizes the milk solids, infusing the cake batter with a nutty sweetness that complements both the sharp coffee and warm cinnamon. Paired with softened cream cheese, it gives the cake a tight, incredibly tender crumb that stays soft for days without drying out.

Tips for Getting It Right

• Chill the Crumble: Don’t skip chilling the crumb topping in the fridge! Cold butter clumps hold their shape in the hot oven, giving you defined, crunchy cookie clusters on top.
• Don’t Over-Swirl: Limit your knife or skewer to 2 or 3 figure-eight motions. Over-swirling will blend the cinnamon and coffee batters into one brown layer instead of distinct marbled ribbons.
• Tent with Foil: Keep an eye on the cake around the 35-minute mark. Tenting loosely with foil protects the chocolate chips and crumble from getting too dark while allowing the center to bake through completely.

Storage and Reheating

• Storage: Store leftover cake in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days.
• Reheating: Warm individual slices in the microwave for 10–12 seconds to soften the chocolate chips and re-awaken the brown butter and cinnamon spices!

Frequently Asked Questions (FAQ)

Q. Can I use mini chocolate chips instead of regular ones?

Yes! In fact, mini chocolate chips work best for the crumble because they disperse evenly throughout the flour clumps without weighing down the topping.

Q. Can I bake this in a loaf pan instead of a 23 cm round pan?

Since this recipe is scaled up for a 23 cm (9-inch) round cake, the batter volume is too large for a standard loaf pan. If using a loaf pan, divide the recipe by half or bake in two standard loaf pans!

Q. What if my cream cheese has lumps when whisking?

Ensure your cream cheese is completely at room temperature before adding it to the warm brown butter mixture. Whisk vigorously, or pass it through a fine sieve if needed.
