Ingredients in Buttermilk Mango-Berry Crumb Cake
Let’s talk about what goes into this delicious creation. You’ll need a few simple ingredients, but trust me—they come together to make something extraordinary:
For the Cake:
- Buttermilk – This gives the cake its rich, tender texture. It’s the secret ingredient to making the cake extra soft and moist.
- All-purpose Flour – The base for the cake. You’ll need just enough to hold everything together without making the cake too heavy.
- Sugar – A little sweetness to balance the tangy buttermilk and fruit.
- Baking Powder & Baking Soda – These help the cake rise and become light and fluffy.
- Eggs – These help bind everything together and keep the cake moist.
- Salt – A pinch of salt to enhance the sweetness and balance the flavors.
- Vanilla Extract – For a warm, aromatic flavor that complements the fruit.
- Butter – Melting the butter adds richness and flavor to the cake.
For the Fruit:
- Mango – Fresh mango adds a tropical sweetness that’s a game-changer in this cake.
- Mixed Berries – Blueberries, raspberries, or blackberries (or all three!) add a sweet-tart bite that balances the richness of the cake.
For the Crumb Topping:
- Flour – A bit of flour for the perfect crumb texture.
- Sugar – To sweeten the topping and help it crisp up in the oven.
- Butter – Cold butter to make the crumb topping just right—flaky and buttery.
- Cinnamon – Adds warmth and depth to the topping.
Instructions
Ready to bake this beauty? Let’s get started!
Preheat the Oven
Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round or square baking pan (or line it with parchment paper for easy removal later on).
Make the Crumb Topping
In a small bowl, mix together the flour, sugar, and cinnamon. Add the cold cubed butter and, using a pastry cutter or your fingers, work the butter into the dry ingredients until you have a crumbly mixture. Set it aside while you prepare the cake batter.
Make the Cake Batter
In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt. In a separate bowl, whisk the eggs, buttermilk, melted butter, and vanilla extract. Pour the wet ingredients into the dry ingredients and mix until just combined. Be careful not to overmix—you want the batter to stay light and airy.
Fold in the Fruit
Gently fold in the mango chunks and mixed berries. Try not to mash the fruit—just fold it in carefully so each bite has a nice burst of fruit.
Assemble the Cake
Pour the batter into the prepared pan and spread it out evenly. Sprinkle the crumb topping over the batter, making sure it’s evenly distributed across the top. You can be generous with this part—more crumb topping means more delicious crunch!
Bake to Perfection
Bake the cake for 40–45 minutes, or until a toothpick inserted into the center comes out clean (a few moist crumbs are fine). The top should be golden brown, and your kitchen will smell amazing by now.
Cool and Serve
Let the cake cool for at least 15 minutes before slicing. While it’s tempting to dive in right away, giving it a little time to set makes for cleaner slices and better texture. Serve warm or at room temperature, and top with a dusting of powdered sugar if you like.

How to Serve Buttermilk Mango-Berry Crumb Cake
This cake is perfect as a stand-alone treat, but here are a few ideas to elevate it:
- Top with Whipped Cream: A dollop of lightly sweetened whipped cream adds a cloud-like touch.
- Pair with Ice Cream: Vanilla ice cream or coconut milk ice cream makes this cake feel extra indulgent.
- Serve for Brunch: This cake is the perfect sweet addition to a brunch spread, paired with fresh fruit and a pot of coffee.
- With Greek Yogurt: For a tangy contrast, serve with a spoonful of Greek yogurt.
Additional Tips
- Fruit Substitutes: If mango isn’t in season, peaches or pears are a great alternative. You can even use a mix of fruits like strawberries, blueberries, or apples.
- Make it Dairy-Free: Use almond milk or another dairy-free milk and substitute a dairy-free butter for a dairy-free version.
- Storing Leftovers: Store leftovers in an airtight container for up to 3 days at room temperature. You can also freeze slices for up to a month—just wrap them tightly.
- Double the Crumb Topping: If you love the crumb topping (who doesn’t?), consider doubling it for an extra buttery crunch.
