Nutella Custard Buttercream

Nutella Custard Buttercream – Use this cream for cakes, custards, meringues and other goodies to give them that delicious Nutella flavor without the butteriness of a regular buttercream. The custard base gives this cake frosting a lighter feel, while still providing lots of delicious flavor.

Use this buttercream with any cupcakes or as part of this delicious Hazelnut Meringue Cake. You will love the array of flavors the cake provides!

If you like the hazelnut flavor of the famous Nutella spread, you will absolutely love this Nutella Custard Buttercream! It has the texture of buttercream, without unnecessary greasiness. The suppleness of the Nutella Custard Buttercream allows to pipe the cream on top of cupcakes, while the deliciousness will make this your favorite cake frosting!

If you’ve noticed the trend lately on the blog, this recipe too will be used in an upcoming cake. But if you’re feeling independently creative you can use the Nutella Custard Buttercream to layer a regular yellow sponge cake, or chocolate sponge cake, or any other cake you know how to make before I post that next cake recipe.

Because the filling does not feel greasy like some of the buttercreams do, you will really be tempted to just eat or ‘taste-test’ this cream by the spoonfuls. Also, if you like your cupcakes topheavy, this is the frosting to do it with.

Do not be surprised though if kids lick the frosting and leave the cupcake behind 😉

    I made this buttercream with Biscoff instead of Nutella and it was delicious.I changed the amount of milk. I put 500ml. Next time I will add an extra half a tbsp flour as I would like it to be more stable.

    Hi there from Sunny South Africa

    I have tried this recipe and it’s out of this world delicious. Thankeeew very much!!
    Finally I have a use for all my left over egg yolks from macarons.

    I made it for the second time today, but for some reason its so liquid, I cooled the egg yolk mixture.
    I can’t understand why

    Please help how can I fix this?

    • Hi Fatima,
      I wonder if your butter wasn’t whipped enough or two runny before you started whipping before adding the custard? Try making sure the butter is not left out for two longe before you whip it, and then whip it for a good 5 minutes before you add the custard. Hope that helps.

    This recipe was amazing and I will make it for my go to. I have a quick question. The recipe indicates, 4 TBSPN 1/4 cup all purpose flour. Is it 4 tablespoons plus 1/4 cup of flour? I know that 4 tablespoons equal 1/4 cup of flour. I erred on the side of caution and did the 4 tablespoons only and it came out okay, but i was just wondering.

    thanks,

    Will revist your site for sure.

    • I have left it out at room temperature for several hours before serving and it was fine. But, I can not tell you what the official rules for food safety are when it comes to this particular recipe. The cake does taste best cold though.

    Wow, I can’t wait to try this!

    Coming from a humid country with all year round temperatures of 28-32 deg celsius, should I immediately refrigerate the custard instead of leaving it to cool? Am concerned that the egg yolks may make it go bad

    • Just spread it on a baking sheet (to speed up cooling) and cover with plastic wrap touching the custard (to prevent film from forming) to help it cool quicker. This will cool a lot quicker and you won’t need to refrigerate it.

    I have always thought your supposed to cool custard fast or refrigerate it as soon as possible because, of the egg yolks. Is this recipe correct to cool it at room temperature?? Every baker I asked said you could get food poisoning from room temperature egg yolks if set out to long so custard needed to be cooled immediately is this wrong or would it be safe to use your method? Love your website and all the beautiful cakes. I love to bake and this cake would be perfect for my grandson as he like your dad loves all the same flavors. Thanks again for the wonderful recipes can’t wait to try the peaches and cream cake. Also do you have recipes for the full cakes or are they all just one layer done two times?

    • Hi Debbie,
      Thank you so much for your question and your kind comments!

      As to the custard, if you have couple gallons of the egg yolk custard then yes you want to do whatever you can to speed up the cooling, otherwise by the time it cools it can spoil.

      In our case, the amount of custard is so small that it cools very fast, probably in about 30 minutes or less. That has never been enough to spoil the custard. Any way you do cool it, you need to make sure that the custard is room temperature when you add it to the whipped butter, otherwise the buttercream will separate.

      Nevertheless if you would like to speed up the cooling process, you can spread the custard on a baking sheet and cover it with plastic wrap touching the custard. This will cool it super quick.

      Hope this answers your question!

    Hi, how long do you cook this on the stove for?

        The buttercream turned out too runny, what can i do to fix it?
        Also now looking back, was it supposed to cool before mixing in with the butter?
        If so, i would clarify that in the recipe.

        • Hi Yana,
          You are so right, the custard must be cool before adding to the butter.
          If you already added the butter to the warm custard, I would completely chill, then try to assemble the cake in the cake ring. So sorry for this, somehow it got missed when I typed the instructions :(.

        I think this would be valuable info to include in the instructions.

        Also, the 1.5 sticks butter, room temp or cold butter?

        Thanks!

        • Hi Inna,
          Anytime you need to cream or whip butter you want to use room temperature butter. I’ll include it in the recipe 🙂

    Hi Marina, do you think this cream would be ok for cream puffs?
    Thank you

    • Hi Gina,
      The flavor combination would be amazing, although I would probably reduce the butter amount by half if I were to use it for cream puffs. Since I haven’t tested it myself though, I can’t guarantee the results. If you do try it, let me know 🙂

    Does the cake need to be stored in the refrigerator after decorating the cake? I know a regular custard needs to be refrigerated, therefore I am assuming that the cake needs refrigerating too.
