Eighteen items and an hour and twenty minutes, and the last two minutes happen just before serving.
There are two batters here, and one is made from the other. A portion of the chocolate mix is stirred with mashed banana and spooned in as a middle band.
Why This Recipe Works
- Buttermilk keeps a cocoa cupcake tender rather than dry and tight.
- A banana-enriched middle layer bakes into a visible pale band.
- Covering it with chocolate batter keeps the band inside rather than on top.
- Tinting half the cream with preserves gives the two-tone swirl without dye.
- Adding banana slices at the last moment stops them browning on the cream.
Ingredient Notes
- One ripe banana, mashed
- For the batter band. Mixed into a portion of the chocolate batter and spooned in as the middle of three layers.
- Two bananas, sliced just before serving
- Separate from the mashed one, and added at the very last moment because cut banana browns quickly on cream.
- Strawberry preserves
- Two tablespoons, stirred into half the whipped cream. That is what makes the pink swirl — there is no colouring in it.
- Caramel sauce, chocolate sauce and sprinkles
- A third of a cup each and two tablespoons. Three finishing components the title names none of.
How to Make It
Oven to 350°F, a twelve-cup pan lined
Heat oven to 350°F and line a 12-cup muffin pan.
Chocolate batter made
Make chocolate batter with flour, cocoa, leaveners, salt, butter, sugar, eggs, buttermilk, and vanilla.
Three spoonfuls per case: chocolate, banana-enriched, chocolate
Spoon a thin chocolate layer into each liner, add a spoonful of mashed-banana-enriched batter made by mixing some batter with mashed banana, then cover with remaining chocolate batter so a pale banana band remains inside.
Baked eighteen to twenty-two minutes, cooled completely
Bake 18 to 22 minutes until set; cool completely.
Cream whipped, half tinted pink, piped in alternating swirls
Whip cream with powdered sugar. Tint half pale pink with strawberry preserves and pipe alternating white and pink swirls.
Banana slices immediately before serving, then the drizzles and sprinkles
Add fresh banana slices immediately before serving, then drizzle with caramel and chocolate and finish with chocolate sprinkles.
Two Bananas, Doing Two Completely Different Jobs
The ingredient list carries bananas twice, in two separate entries, and they are not interchangeable. One is mashed into batter and baked in the middle of the cupcake; the other is sliced at the last possible moment and never sees heat at all. Confusing them is how this recipe goes wrong in both directions.
Stage 1 of 5
The chocolate batter - buttermilk keeps it tender
Steps 2–2 of 6
1 1/4 cups FLOUR, 1/3 cup COCOA, 1 tsp baking powder, 1/2 tsp baking soda, 1/4 tsp salt, 1/2 cup softened BUTTER, 3/4 cup SUGAR, 2 EGGS, 1/2 cup BUTTERMILK and 1 tsp VANILLA. Cocoa is drying and buttermilk is the counterweight - its acidity also wakes the baking soda, which is why both leaveners are here rather than one.

Stage 2 of 5
THREE spoonfuls per case, and the middle one is different
Steps 3–3 of 6
A THIN CHOCOLATE LAYER first, then A SPOONFUL OF BANANA-ENRICHED BATTER - made by mixing SOME OF THE SAME BATTER with the 1 MASHED RIPE BANANA - then COVERED with the remaining chocolate batter SO A PALE BANANA BAND REMAINS INSIDE. The pale band is BAKED BATTER, not a raw filling piped in later. Keep the middle spoonful small - overfill it and the band becomes a whole pale half, and cover it properly or it bakes to the surface instead of staying enclosed.

Stage 3 of 5
18 to 22 minutes, then COOLED COMPLETELY
Steps 4–4 of 6
Baked UNTIL SET. Cooling completely is not optional here because whipped cream is going onto these: piped onto a warm cupcake it melts, slumps off the side and takes the drizzles with it. Cupcakes cool quickly out of the tin, so lift them out as soon as they are firm enough to move.

Stage 4 of 5
The cream - HALF tinted, with PRESERVES not colouring
Steps 5–5 of 6
1 cup HEAVY CREAM whipped with 2 tbsp POWDERED SUGAR, then HALF of it TINTED PALE PINK WITH 2 tbsp of STRAWBERRY PRESERVES and PIPED IN ALTERNATING WHITE AND PINK SWIRLS. The preserves are doing the colouring and the flavouring at once, which is why the pink swirl in the photograph is flecked rather than uniform. Fold them in gently - beating jam into whipped cream knocks it back down to liquid.
- Cream whipped, half tinted pink, piped in alternating swirlsWhip cream with powdered sugar. Tint half pale pink with strawberry preserves and pipe alternating white and pink swirls.
Stage 5 of 5
The last stage happens AT THE TABLE
Steps 6–6 of 6
2 BANANAS SLICED IMMEDIATELY BEFORE SERVING, then 1/3 cup CARAMEL, 1/3 cup CHOCOLATE SAUCE and 2 tbsp SPRINKLES. The timing is the difference between fresh banana and a plate of brown-edged fruit - cut banana oxidises within minutes and does it faster resting on cream. The caramel and sprinkles are components the title names neither of. And there is NO CHERRY: a banana split conventionally has one and these deliberately do not. Cream-topped, these are a 40°F OR BELOW item.
- Banana slices immediately before serving, then the drizzles and sprinklesAdd fresh banana slices immediately before serving, then drizzle with caramel and chocolate and finish with chocolate sprinkles.
Success Tips
- Keep the banana batter to a single spoonful so the band stays a band.
- Cool the cupcakes completely before piping or the cream slides off.
- Slice the bananas at the table, not in advance — they brown within minutes.
Serving Ideas
Twelve dark chocolate cupcakes with a pale banana band visible through the case, topped with alternating white and pink cream swirls, fresh banana slices, caramel and chocolate drizzles and chocolate sprinkles.
Frequently Asked Questions
What is the pale band inside the cupcake?
A baked layer of the same chocolate batter mixed with mashed banana. It is spooned in between two chocolate layers and bakes with them — it is not a filling piped in afterwards.
When do the banana slices go on?
Immediately before serving. Cut banana browns fast, especially sitting on cream, so it is the last thing that happens.
Should there be a cherry on top?
Not on these. A banana split conventionally carries one, but this recipe does not — the toppings are cream, banana, caramel, chocolate and sprinkles.
