Instructions

Let’s dive into the steps to create this fruity, crumb-topped masterpiece.

Preheat Your Equipment

Start by preheating your oven to [temperature]. A properly heated oven ensures the cake bakes evenly and gets that perfect golden top.

Combine Dry Ingredients

In a large mixing bowl, whisk together the flour, baking powder, baking soda, and salt. This helps evenly distribute the leavening agents so the cake rises just right.

Mix Wet Ingredients

In a separate bowl, mix together the buttermilk, eggs, vanilla extract, and sugar. Stir until smooth and slightly frothy—it should smell like sweet vanilla heaven.

Combine Ingredients

Pour the wet mixture into the dry ingredients and stir gently until just combined. Don’t overmix—just enough to bring everything together. The batter will be thick, and that’s exactly what we want.

Fold in the Fruit

Gently fold in the diced mango and berries. Be careful not to crush the berries too much; we want them to stay juicy and intact.

Prepare Your Baking Dish

Grease your baking dish or line it with parchment paper. This ensures your cake comes out cleanly and makes cleanup way easier.

Assemble the Cake

Pour the batter into the prepared dish and smooth the top with a spatula. Now comes the best part: the crumb topping!

Add Crumb Topping

In a small bowl, mix flour, sugar, a pinch of salt, and cold butter until it resembles coarse crumbs. Sprinkle generously over the top of the batter.

Cook to Perfection

Bake for [time duration], or until the top is golden brown and a toothpick inserted in the center comes out clean. Your kitchen will smell like a dream.

Finishing Touches

Let the cake cool for at least [cooling time]. This helps the fruit set and the crumb topping get that perfect texture.

Serve and Enjoy

Slice and serve as is, or dress it up with a dollop of whipped cream or a scoop of vanilla ice cream. You’ve officially created a cake worth celebrating.
