¾ cup (150g) granulated sugar

3 tablespoons unsalted butter
2 tablespoons milk
½ teaspoon vanilla extract
¾ cup (90g) powdered sugar, sifted

Step-by-Step Method

Step 1: Prep the Pan and Oven

First things first, preheat your oven to 350°F (175°C). Grease a standard 9×5-inch loaf pan and line it with parchment paper, leaving a little overhang on the sides for easy lifting later.

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together the flour, baking soda, and salt. This will ensure even distribution of the leavening agent and salt throughout the bread.

Step 3: Cream Butter and Sugar

In a large bowl, use an electric mixer to beat the softened butter and granulated sugar together until light and fluffy — about 3 to 4 minutes. This step is crucial for a tender, airy texture.

Step 4: Add Eggs and Vanilla

Beat in the eggs, one at a time, making sure each is fully incorporated before adding the next. Stir in the vanilla extract for an added depth of flavor.

Step 5: Introduce Bananas and Sour Cream

Mix in the mashed bananas and sour cream. The batter might look a bit lumpy, but that’s perfectly fine — it will smooth out once the dry ingredients are added.

Step 6: Combine Wet and Dry

Gradually add the dry ingredients to the wet ingredients, stirring gently with a spatula. Mix just until the flour disappears — overmixing can lead to a dense loaf.

Step 7: Create the Chocolate Batter

In a small bowl, combine the cocoa powder and milk. Scoop out about one-third of the banana batter and mix it thoroughly with the cocoa mixture to create the chocolate batter.

Step 8: Assemble the Marble Effect

Drop alternating spoonfuls of the plain and chocolate batters into your prepared loaf pan. Once all the batter is in, use a skewer or butter knife to gently swirl through the batter a few times. Tip: Less swirling means more distinct, beautiful marbling!

Step 9: Bake the Loaf

Place the pan into the preheated oven and bake for 55–65 minutes. Check doneness by inserting a toothpick into the center — it should come out mostly clean with a few moist crumbs.

Step 10: Cool the Bread

Let the bread cool in the pan for 15 minutes, then lift it out using the parchment paper. Transfer to a wire rack to cool completely before glazing.

Making the Caramel Glaze

Step 11: Prepare the Caramel Base

In a small saucepan, combine the brown sugar, butter, and milk over medium heat. Stir continuously until the mixture comes to a boil. Once boiling, allow it to bubble for exactly 1 minute, then remove it from heat.

Step 12: Add Flavor and Body

Stir in the vanilla extract. Gradually whisk in the sifted powdered sugar until the glaze becomes thick but still pourable. If it’s too thick, a tiny splash of milk will loosen it up.

Step 13: Glaze the Bread

Place the fully cooled banana bread on a wire rack with a tray underneath (to catch excess glaze). Drizzle the warm caramel glaze generously over the loaf, letting it drip down the sides naturally.

Expert Tips for Best Results

Use extremely ripe bananas — the blacker, the better!
Swirl gently — too much swirling will muddy the distinct marbled look.
Sift your powdered sugar — it prevents lumps in the caramel glaze.
Let the glaze set slightly before slicing for a cleaner cut.
