Ingredients in Buttermilk Mango-Berry Crumb Cake
You don’t need much to create this sweet masterpiece. These simple ingredients come together to make something really special:
For the Cake:
- Buttermilk – This is the secret to the cake’s tender texture. It gives it a richness that regular milk just can’t match.
- All-purpose Flour – The base of the cake. You’ll need just the right amount for a soft, fluffy crumb.
- Sugar – Sweetens the cake just enough without overpowering the fruit.
- Baking Powder & Baking Soda – To help the cake rise and create that airy, light texture.
- Eggs – These help bind the ingredients together and make the cake wonderfully moist.
- Salt – A pinch to balance the sweetness and enhance the flavors.
- Vanilla Extract – For that extra touch of warmth and depth of flavor.
- Butter – Adds richness and flavor to the cake. Be sure to melt it for a smoother texture.
For the Fruit:
- Mango – Fresh mango chunks add a tropical sweetness that pairs perfectly with the berries.
- Mixed Berries – I love a combo of blueberries, raspberries, or blackberries, but feel free to mix and match your favorites.
For the Crumb Topping:
- Flour – A little flour creates the perfect crumbly texture.
- Sugar – Sweetens the topping and helps it crisp up in the oven.
- Butter – Cold butter, cut into small cubes, creates that crunchy, buttery topping.
- Cinnamon – Adds a cozy, warm flavor to the crumb topping.
Instructions
Let’s get baking! This cake comes together so quickly, you’ll have it in the oven in no time.
Preheat Your Oven
Start by preheating 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.
Make the Crumb Topping
In a small bowl, combine the flour, sugar, and cinnamon. Add the cold cubed butter and use a pastry cutter or your fingers to work it into the dry ingredients until you get a crumbly texture. Set this 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 together the eggs, buttermilk, melted butter, and vanilla extract. Pour the wet ingredients into the dry ingredients and mix until just combined. Don’t overmix—lumps are okay.
Fold in the Fruit
Gently fold in the mango chunks and mixed berries, being careful not to mash the fruit. You want to keep those vibrant colors and juicy pockets of fruit in every bite.
Assemble the Cake
Pour the batter into your prepared pan and spread it out evenly. Sprinkle the crumb topping over the batter, making sure it’s evenly distributed across the top. Don’t be shy with the crumb topping—it’s one of the best parts!
Bake to Golden Perfection
Bake for 40–45 minutes, or until a toothpick inserted into the center of the cake comes out clean (a few moist crumbs are okay). The top should be golden brown and the house will smell like heaven by this point.
Cool and Serve
Allow the cake to cool for at least 15 minutes before slicing into it. It’s tempting to dive right in, but letting it cool just a little helps the cake set and makes it easier to slice. Serve warm or at room temperature with a dusting of powdered sugar if you like.

How to Serve Buttermilk Mango-Berry Crumb Cake
This cake is perfect on its own, but here are some ideas to make it even more indulgent:
- With Whipped Cream: A dollop of freshly whipped cream adds a light, airy touch to each slice.
- With Ice Cream: Vanilla or coconut ice cream would be a heavenly pairing with the warm cake.
- For Brunch: Serve it alongside a fresh fruit salad and a pot of coffee or tea for a delicious brunch spread.
- Topped with Yogurt: A spoonful of Greek yogurt adds a creamy tang that balances the sweetness of the fruit and cake.
Additional Tips
- Fruit Substitutes: If mango isn’t in season, swap it for peaches, nectarines, or even apples. Berries are always a great option, too.
- Make it Dairy-Free: Substitute the buttermilk with a dairy-free alternative like almond milk mixed with a splash of lemon juice to mimic the acidity.
- Storing Leftovers: This cake stays fresh for a few days when stored in an airtight container at room temperature. You can also freeze slices for up to a month—just be sure to wrap them tightly!
- Extra Crumb Topping: If you’re a fan of the crumb topping (who isn’t?), double the amount for an even more decadent treat.
FAQ Section
Q1: Can I use frozen berries?
A1: Yes! Frozen berries work just as well as fresh. Just toss them in a little flour before folding them into the batter to prevent them from sinking to the bottom.
Q2: Can I make this cake ahead of time?
A2: Absolutely! You can bake the cake a day ahead and store it at room temperature. The flavors actually improve overnight.
Q3: Can I use regular milk instead of buttermilk?
A3: You can, but the texture and flavor won’t be quite the same. If you don’t have buttermilk, make your own by adding 1 tablespoon of lemon juice or vinegar to a cup of regular milk and letting it sit for 5 minutes.
Q4: Can I use a different kind of fruit?
A4: Totally! Swap out the mango and berries for whatever fruit is in season, like pears, apples, or stone fruits.
Q5: Can I make this cake gluten-free?
A5: You can substitute the flour with a gluten-free all-purpose flour blend. Just make sure it has xanthan gum or another binder to help with texture.
