Banana Split Eclairs

Banana split eclairs—I know shut-up, right? But really you should, so you can stuff your face with these (and when you are done don’t forget to make these S’mores Eclairs too).  And yes, they taste as good as they look—hard to go wrong with a banana cream stuffed pate choux covered in chocolate.

There’s a little story behind this recipe—if you follow me on Twitter then you know two weeks ago I tweeted about some pastry cream looking like mustard.  That was the first run of the banana pastry cream. It tasted great but looked horrible—it was grey, so I tried to tint it with yellow coloring. Disaster.

It looked like mustard—not very appetizing, so I dumped it. Yes, I dumped it. I couldn’t get past the mustard color enough to even enjoy the flavor and neither could my family.  Down the sink it went. After the mustard fiasco, I decided to just flip the banana pastry cream to a diplomat cream (diplomat cream being a combination of pastry cream and whipped cream).

That did the trick on the coloring, while also lightening the texture of the banana pastry cream. Round two of family testing was a huge hit. Only problem, Matt and Cole requested theirs with no sprinkles.  Seriously, Family, we are three years into this blog, no custom orders please.

On a side note, if anyone knows how to color grey bananas into a light colored yellow – please leave a comment letting the rest of us know.

Banana Split Eclairs




Pate Choux

  • 1 cup water
  • 8 tablespoon butter
  • 2 tablespoon sugar
  • pinch salt
  • 1 ½ cups bread flour
  • 3 large eggs plus 2 egg whites


Banana pastry cream

  • 1/2 cup plus 1 1/2 cup of whole milk
  • ½ cup cornstarch
  • ½ cup plus 2 tablespoon sugar
  • 1 large egg
  • 3 large egg yolks
  • ¾ cups of banana, mashed (about two medium bananas)
  • pinch of salt
  • 4 tablespoon unsalted butter
  • 2 teaspoon vanilla

Whipped Cream

  • 1 cup heavy cream
  • ½ cup confectioner sugar

Chocolate glaze

  • 4 oz. chocolate, 65% cacao
  • 2 tablespoons heavy cream
  • 4 tablespoons powdered sugar, sifted
  • 4-5 tablespoons water, warm



Preparation: Heat oven to 400 degrees F and line bake sheet with parchment paper.

 To make pate choux:
  1. Place water, butter, sugar and salt in a sauce pan and bring to a boil over medium heat.  Remove pan from heat and add bread flour and stir until combined. Return pan to heat and stir in  circular motion until dough forms a ball at the center of pan.  Transfer dough to stand mixer bowl and let rest for 5 minutes.
  2. Fit stand mixer with a whisk attachment. Add in one egg at a time and mix on medium until combined. Add 1 egg at a time and mix until fully incorporated before adding the next. Dough should be smooth, if not mix until dough is free of lumps.
  3. Place dough in pastry bag fitted with a large round tip. Pipe 2-inch lines, two inches apart onto parchment lined pan. Bake at 400 for about 20 minutes or until golden brown. Remove from oven and pierce each one with a paring knife to release the steam.

To make banana diplomat creme

  1. Combine ½ cup milk and cornstarch stir to dissolve.  Add in whole egg,  egg yolks and bananas and beat until well combined; set aside. Prepare an ice bath; set aside.
  2. Combine remaining milk with sugar and salt in a saucepan and bring to a boil over medium heat. Remove saucepan from heat and transfer mixture to a new pan to reduce any residual heat. Set aside and cool milk mixture for 5 minutes.
  3. Slowly add egg mixture into cooked milk mixture, stirring constantly so the eggs do not curdle. Return mixture to stovetop and stir vigorously until mixture comes to a boil. Continue to stir until the whisk leaves a trail in the pastry cream, about 5-7 minutes. Once pastry cream reaches this stage, remove saucepan from heat and stir in butter and vanilla extract. Transfer the saucepan to the ice bath. Stir occasionally until pastry cream is cool about 30 minutes.
  4. Place heavy cream and confectioner sugar in a chilled stainless bowl. Using a hand mixer beat until stiff peaks form. Set aside.
  5. Once banana pastry cream has cooled, combine 1 part whipped cream to 2 parts banana pastry cream.

To make chocolate glaze

  1. Place chocolate and heavy cream in a bowl over simmering water. Let chocolate and cream sit for 2-3 minutes to melt without stirring. Then slowly stir mixture to combine. Add confectioner sugar and mix to combine. Add water 1 tablespoon at a time, mixing after each addition until pouring consistency is reached. Set aside and let sauce cool to warm.


  1. Cut the side of each éclair and fill with banana crème diplomat. Place filled eclairs on a cooling rack and with parchment paper lined underneath (to catch chocolate drips). Pour chocolate glaze on top (warm glaze as needed to keeping pouring consistency).  Place sprinkles on top. Using the remaining whipped cream, pipe a dollop on top of chocolate and finish with a maraschino cherry.

A few notes:

  1. The diplomat crème is a combination of pastry cream and whipped cream.  You can skip the whipped cream and just fill the eclairs with banana pastry cream, but keep in mind the banana cream will have a greyish tint to it.  I made this a diplomat cream to help to lighten the color, since adding any yellow food coloring to the banana pastry cream seemed to give it a mustard color. Along with that the whipped cream and will also lighten the texture of the pastry cream.
  2. To stay ahead, make the filling a the chocolate glaze a day in advance.  Heat the chocolate glaze in the microwave for ten second intervals checking and stirring in between until pouring consistency is achieved.

    Love this fabulous twist on the Banana Split Sundae, Naomi! You can never go wrong combining bananas, pastry cream, fresh whipped cream and cream puffs shaped into eclairs drizzled with chocolate glaze with sprinkles and a cherry on top!

    First off: Oh my god, I am in love with these eclairs. And I think the sprinkles are 100% necessary- aren’t they always?
    Secondly: Your banana cream-color problem reminds me of the note Christina Tosi added in Milk Bar to accompany her banana cream pie recipe. Basically, she calls for a load of food coloring, with little apology, explaining that without the dye, the pie will be grey and pretty unappetizing. The photos of her pie do look a little like mustard, and I would assume that she’s tested different amounts/types of food coloring, so perhaps it’s mustard or bust when it comes to bananas.

    Such an awesome idea! They look delicious – I doubt I’ll be able to stop after eating just 1 :-)

    These are absolutely adorable – I could imagine they’d be a great hit at a children’s birthday party, school fete or afternoon tea with the girls. You’re never too old to enjoy sprinkles.

    These are perfect! Found the best app for sharing recipes ever! It’s called Heirloom Recipes my sister just got it today and emailed me a recipe and I got the free version to try it and OMG I imported the recipe right into the app no typing or anything! The email had the link to the free one: I’m going to put this recipe in it and send it back to her but I’m going to use the photo you posted to make her jealous. LOL!!! There’s no way she can top these stunning Eclairs.

    In one of her ice cream recipes, Jeni Britton Bauer uses a tiny bit of turmeric to create a soft yellow tint. It doesn’t add any flavor (that I could discern, anyway). Perhaps that would work here.

    Add “Fruit Fresh” to your recipe to preserve the true color of the bananas. Fruit Fresh has no artificial stuff in it and can be found in most markets. I use it in my banana bavarian recipe. It works!
