Ingredients

• For the Cake:
• 2 ripe bananas, mashed
• 1 cup all-purpose flour
• 1 cup granulated sugar
• ½ cup unsweetened cocoa powder
• 1 tsp baking powder
• 1 tsp baking soda
• ½ tsp salt
• 1 cup milk
• 2 large eggs
• ½ cup unsalted butter, melted
• 1 tsp vanilla extract
• For the Milk Mixture:
• 1½ cups whole milk
• ½ cup sweetened condensed milk
• 1 tsp vanilla extract
• For the Chocolate Ganache:
• 4 oz semi-sweet chocolate, chopped
• ½ cup heavy cream
• 1 tbsp unsalted butter

Substitution Options

If you’re out of certain ingredients, no worries! Here are some swaps:

• Use almond or oat milk instead of whole milk for a dairy-free option.
• Swap coconut oil for butter if you want a vegan-friendly cake.
• Dark chocolate can replace semi-sweet chocolate for a deeper flavor.
• Brown sugar works as a substitute for granulated sugar if you prefer a caramel-like taste.

Step 1: Preparing the Cake Batter

Start by preheating your oven to 350°F (175°C). Grease and flour an 8×8-inch square baking pan—I always use parchment paper too, just in case. In a large bowl, whisk together the dry ingredients: flour, sugar, cocoa powder, baking powder, baking soda, and salt. In another bowl, mix the wet ingredients: milk, eggs, melted butter, mashed bananas, and vanilla extract. Gradually pour the wet mixture into the dry ingredients, stirring until smooth. The batter will be thick and fragrant, with a hint of banana aroma.

Pro tip: Mash the bananas well to avoid lumps in the batter. Ripe bananas are key—they’re sweeter and softer, which makes the cake extra moist.

Step 2: Baking the Cake

Pour the batter into the prepared pan and spread it evenly with a spatula. Pop it into the oven and bake for 25-30 minutes. You’ll know it’s done when a toothpick inserted in the center comes out clean. The cake will rise slightly and have a deep chocolate-brown color with a faint banana scent wafting through your kitchen. Let it cool completely before moving on to the next step.

Chef’s tip: Don’t rush the cooling process! A warm cake will absorb the milk mixture unevenly, which could ruin the texture.

Step 3: Making the Milk Mixture

In a saucepan, heat the whole milk and sweetened condensed milk over medium heat until warm—not boiling. Remove from heat and stir in the vanilla extract. This mixture should be smooth and creamy, with a subtle sweetness. Once the cake has cooled, use a fork to poke holes all over the surface. Slowly pour the milk mixture over the cake, letting it seep into every crevice. The cake will soak it up like a sponge, becoming irresistibly moist.

Pro tip: Be patient while pouring the milk mixture. Go slow to ensure even absorption.

Step 4: Preparing the Chocolate Ganache

For the ganache, heat the heavy cream in a small saucepan until it simmers. Pour it over the chopped chocolate and butter in a bowl, then let it sit for a minute before stirring. The result is a glossy, velvety ganache that smells divine. Let it cool slightly before spreading it over the soaked cake. The ganache will set beautifully, creating a rich, decadent finish.

Chef’s tip: For a thicker ganache, refrigerate it for 10 minutes before using.

Timing

Here’s how long each part of the process takes:

• Prep time: 15 minutes
• Cooking time: 30 minutes
• Resting time: 20 minutes (for cooling and soaking)
• Total time: 1 hour and 5 minutes

Chef’s Secret

To make the cake extra special, sprinkle a pinch of sea salt on top of the ganache before serving. The salt enhances the sweetness and balances the richness of the chocolate.

Extra Info

Did you know bananas are technically berries? Yep, they belong to the same family as blueberries and strawberries. Nature sure knows how to pack flavor into these little fruits!

Necessary Equipment

You’ll need a few basic tools to make this cake:

• 8×8-inch square baking pan
• Mixing bowls
• Whisk and spatula
• Saucepan
• Fork or skewer (for poking holes)

Storage

Store leftover cake in an airtight container at room temperature for up to 3 days. If you live in a warm climate, refrigerate it for up to 5 days. The cake stays moist thanks to the milk mixture, but chilling it can firm up the ganache slightly.

If you plan to freeze the cake, wrap individual slices in plastic wrap and place them in a freezer-safe bag. They’ll keep for up to 2 months. Thaw overnight in the fridge before serving.

For best results, bring the cake to room temperature before enjoying it. This allows the flavors to shine and the textures to soften.

Tips and Advice

Here are a few tips to elevate your Decadent Choco-Banana Milk Cake:

• Use very ripe bananas—their sweetness enhances the cake’s flavor.
• Don’t skip the resting time after adding the milk mixture. Patience pays off!
• Top the cake with whipped cream or fresh banana slices for extra flair.

Presentation Tips

Make your cake look as good as it tastes:

• Dust powdered sugar over the ganache for a snowy effect.
• Add edible flowers or sprinkles for a pop of color.
• Serve slices with a dollop of whipped cream and a drizzle of caramel sauce.

Common Mistakes to Avoid

Mistake 1: Overmixing the Batter

Overmixing can lead to a dense cake instead of a light and fluffy one. Mix just until the ingredients are combined. Remember, a few lumps are okay!

Tip: Use a gentle folding motion when combining wet and dry ingredients.

Mistake 2: Skipping the Cooling Step

A warm cake won’t absorb the milk mixture properly. Always let it cool completely before soaking.

Tip: Set a timer to remind yourself not to rush this step.

Mistake 3: Burning the Ganache

Heating the cream too quickly can scorch it, ruining the ganache. Keep the heat low and watch closely.

Tip: Stir constantly while heating the cream to prevent burning.

Use a sharp knife dipped in hot water. Wipe the blade between cuts for clean slices.
