Melt-in-your-mouth cookies filled with a sweet and zest silky passionfruit buttercream, the perfect passionfruit melting moments.
What is a melting moment?
Melting moments are a classic Australian cookie! They are sandwich cookies made with silky buttercream and two melt-in-your-mouth cookies.
The melt-in-your-mouth texture comes from the use of cornstarch or custard powder. The cookie itself is similar to shortbread cookies, but with a finer texture that disappears in your mouth.
Traditionally they are filled with a lemon filling, but I've opted for passionfruit instead. This results in a fruitier and tangier buttercream that goes perfectly with the buttery cookie.
- Unsalted butter: Make sure you use room temperature butter as it will make it a lot easier to incorporate the rest of your ingredients
- Powdered sugar: Aka icing sugar, is needed to give the cookies sweetness without a grainy texture
- Custard powder: Custard powder is the secret to that melt-in-your-mouth texture. If you can't find any custard powder you can use cornstarch (aka corn flour) instead. Keep in mind that the cookies won't be as sweet so I would add another tablespoon or two of icing sugar to balance it out.
- All-purpose flour: Aka plain flour, makes up the structure of the cookie! Make sure you don't overmix your cookies otherwise they can turn out very dense.
- Unsalted butter: Make sure you use room temperature butter as this will help the passionfruit pulp incorporate smoothly into the buttercream.
- Powdered sugar: The sugar here gives the buttercream sweetness, you can increase or decrease this according to your personal preferences
- Passionfruit pulp: You can use canned or fresh passionfruit pulp. If you are using canned passionfruit pulp make sure you drain out the excess liquid before adding it to your buttercream otherwise the buttercream will be too wet and split.
Frequently Asked Questions
How long do these last?
These cookies will last up to 3 days when stored in an airtight container on your countertop, or up to a week when stored in an airtight container in the fridge.
If you do store them in the fridge make sure you leave them out at room temperature to soften up before eating. This will ensure that they are at the right temperature to melt in your mouth.
How should I store these?
I recommend storing melting moments in an airtight container on your countertop. This preserves the texture of the cookie, making sure it is at its optimal flavor and texture for consumption.
If you want these to last longer you can store the cookies and the cream separately from each other. This prevents the cookies from absorbing too much moisture and becoming soft.
Can I change the flavor?
Yes, you can! There are so many different ways you can switch up the fillings.
I highly recommend adding some lemon zest and lemon juice to the buttercream instead of passionfruit pulp. Or even adding a jam like strawberry or marmalade to the buttercream instead of the passionfruit.
If you like a classic vanilla flavor then leave out the passionfruit altogether and add a splash of vanilla extract instead!
Why is my buttercream splitting?
This buttercream is sensitive to splitting as we are adding passionfruit pulp to it. Passionfruit pulp, depending on where you get it from can be wetter or drier. I recommend placing your passionfruit pulp in a fine-meshed sieve and letting any excess passionfruit juice drip from the pulp before adding it to the buttercream.
If the buttercream does split as you are whisking it don't worry. Just increase the speed of your mixer to high and continue to beat it until it comes together. It might take a little longer than usual but it will come together eventually.
