Chocolate Banana No Bake Custard Cake

Piece of cake on a white plate topped with decorations.

No bake desserts are a real saver when the weather is just too much to be turning on the oven, but you want something nice for dessert.  This chocolate and custard dessert is exactly what you need – with chocolate graham crackers, half the work is already done for you, so all you need to do is make the custard and assemble this beautiful and delicious custard cake.

This recipe came to me one day when I had a couple of leftover egg yolks from a different recipe. In the following days I made it several times, both with the addition of banana and without, but found that banana was a really nice addition to the flavors that are already there.

As I was getting done making this cake I was super excited, because I knew that it was going to be amazing even before the first bite. When you add chocolate, custard and bananas it just can not be bad. When I did have the first bite, it was incredible! It’s nice that it is only a 9 inch cake and I have more than one person in my family, otherwise it would be too tempting to just get a spoon and go at it until you see the other border of the baking dish lol.

With the 4th of July coming around the corner, you can decorate this Chocolate Banana No Bake Custard Cake with some fresh berries (raspberry, blueberry) for a nice pop of color.

Alright you guys, I really hope you get around to making this cake because it’s so so good! You will not be disappointed! Chao!
P.S. Stay safe this 4th of July!

Tip #1
For a clean slice, dip a sharp thin knife into hot boiling water for 10 seconds, wipe with a paper towel and proceed to cut. Do so every time you make a new cut.

Tip #2:
I love using this cookie spatula from OXO for removing slices, because it is thin, flexible, glides easily underneath the cake and about the size of each cake slice. I actually use this spatula for virtually everything in the kitchen, from scraping the bowl, to turning stuff in my non-stick skillets.

As an optional step, you can further sprinkle some colored crispearls on top of the Chocolate Banana No Bake Custard Cake. While not a necessary step, it does make for a fun presentation.
See below for instructions on how to color them.Top view of cake topped with pearls in a baking pan.

How to make colored Chocolate Crispearls:

Add White Chocolate Crispearls to a small container that has a close-fitting lid. Sprinkle the Crispearls with a tiny amount of any colored Luster Dust. Close lid. Shake until the Crispearls are evenly covered in shimmer.

    Hi Marina,
    Excited to try coloring my crispy pearls this way! I’m not a fan of colored dragees because of how hard they are when you bite into them

    Hi Marina,
    I just finished making the custard adding 3 cups milk and I see nowhere in directions as to when to add the cream, so I didn’t. (thought it might be for the ganache)
    I see in the instructions that 1/4 cup of the cream goes into the 1/4 chocolate for the ganache.
    Should I have added the cream to the milk for the filling? If so it is probably to late to add now that it is cooked.
    Thank you,
    Carol

    • Hi Carol,
      you can add hot cream to the cooked custard and stir it together, if you haven’t assembled the cake yet, since the cream is to be heated with the milk. So sorry this got missed in the instructions.

  • Hi Lyudmila,
    Thanks so much for your kind words!
    Yes, you can definitely use any kind of similarly flavored/textured cookies/biscuits. Also if they’re about the same thickness, I wouldn’t even crush them, just layer them between the custard and you will be good to go! If the cookies you use are thicker, just let the whole thing sit in the fridge a little longer. Hope this helps!

    Hi Marina,
    As usual, looks yummy-yummy. Would love to make it straight away but cannot find Graham crackers here where I live. Is it possible to substitute them by something else e.g. like crushed chocolate digestives or oreos? Thanks
