White chocolate cookie recipe fans, this one’s for you.
These Custard Cream and White Chocolate Cookies are the cookie equivalent of finding an extra chip at the bottom of the bag. Soft, buttery and packed with creamy white chocolate chunks, they’re loaded with crushed custard cream biscuits that bring a nostalgic crunch to every bite.
As they bake, the smell of vanilla and butter fills the kitchen like a warm hug from your childhood biscuit tin.
The edges turn lightly golden, the centres stay tender, and pockets of melted white chocolate weave through the dough like little ribbons of sweetness. Then come the custard creams, adding bursts of crunch and that unmistakable creamy vanilla flavour that made them a tea-break favourite in the first place.
They’re simple to make, ridiculously moreish, and proof that sometimes the best cookies come from combining two classics into one.
So, what makes these cookies so special?

Why My Custard Cream & White Chocolate Cookie Recipe Is The Perfect Bake
This Custard Cream & White Chocolate Cookie recipe is what happens when a nostalgic biscuit tin favourite meets a proper bakery-style cookie. It’s soft, golden, and just crisp enough at the edges to keep every bite interesting.
I’m using Morrisons Custard Creams because they bring that classic vanilla snap you only get from a proper tea-dunking biscuit. Instead of dissolving into the dough, they bake into crunchy little pockets that keep that familiar custard cream flavour running through the cookie.
Then comes the white chocolate (my favourite)…
I’m using luxury Lindt white chocolate for a reason. It melts into smooth, creamy pools that soften the cookie without making it cakey, giving you that rich contrast against the biscuit crunch.
The custard powder is the quiet hero here.
It doesn’t just add that signature custard cream flavour, it also helps create a finer, more tender cookie texture so the centre stays soft while the edges bake golden.
Now that you know why these cookies work so well, let’s go through exactly what you’ll need to make them.
Custard Cream & White Chocolate Cookie Ingredients (and why they matter)
Every part of this white chocolate cookie recipe has a job, nothing is just there to fill space. This is all about building a cookie that feels soft in the middle, crisp at the edges and loaded with little moments that hit you as you bite in.
Butter
Butter is the flavour base. It’s what gives you that rich bakery taste and those edges that bake golden before melting back into softness as the cookie cools.
Sugar
Sugar is what makes everything happen in the oven. It melts, it spreads, it caramelises slightly and gives you that chewy edge that makes cookies addictive.
Egg
Egg holds it all together so you get structure instead of a tray of melted chaos. It keeps the cookie thick enough to hold all the good stuff inside.
Plain Flour
Plain flour is your backbone. It gives the cookie its body so it can carry the chocolate and custard creams without falling apart.
Baking Powder & Bicarbonate of Soda
Baking powder and bicarbonate of soda are there to give a bit of lift and spread. Just enough to stop it from being dense, not enough to turn it cakey.
Custard Powder
Birds custard powder is the secret ingredient of this bake. It brings that unmistakable custard cream flavour and softens the crumb so the cookie feels tender and almost melt-in-the-mouth.
White Chocolate
White chocolate melts into creamy pools through the dough like little pockets of sweetness that show up when you least expect them.
Custard Creams
Custard creams are the crunch. Little biscuit pieces that bake into the cookie and give you that familiar tea tin hit in every bite.
Now, let’s get into swaps and how you can play around with it.
How To Make These Custard Cream & White Chocolate Cookies
This white chocolate cookie recipe comes together into a soft, rich dough that bakes into thick, golden cookies with crisp edges and gooey white chocolate pockets running through every bite.
The key is simple mixing and not overthinking it. You’re building layers of flavour as you go, from buttery sweetness to chunks of custard cream that bake into little crunchy surprises, almost like finding hidden pieces of biscuit tin nostalgia inside a soft bakery cookie.
Once everything is combined, the dough should feel rich, slightly soft and studded with chocolate and biscuit pieces, ready to transform in the oven into something warm, golden and dangerously moreish.
Step One: Get All Your Ingredients Weighed For This Custard Cream & White Chocolate Cookie Recipe
This white chocolate cookie recipe is at its best when you treat it like a smooth run rather than a scramble. Once the mixing starts, everything moves quickly, and the dough doesn’t wait around for you to catch up.
So before anything hits the bowl, this is your moment to get everything ready. That means weighing ingredients, chopping the white chocolate into rough, uneven chunks so you get those melted pockets later, and breaking the custard creams into rustic pieces that will bake into crunchy little bursts inside the cookie.
Think of it like lining up dominoes so they fall exactly how you want them to. It keeps the process calm, controlled, and saves you from running around like a headless chicken halfway through.
Step Two: The Butter, Eggs & Sugar Method I Used!
This white chocolate cookie recipe starts with butter, sugar, eggs and vanilla coming together to form the base of the dough.
You’re not trying to whip anything pale or airy here, just mixing until everything is combined into a soft, slightly thick mixture.
Once the eggs and vanilla go in, it might look a bit rough or lumpy at first, like it doesn’t quite want to come together.
That’s normal.
Keep mixing, and it smooths out into a dense, rich base that feels more like a thick paste than anything fluffy. This is exactly what you want for a cookie that holds its shape and bakes into something soft in the middle with crisp edges rather than spreading into a flat puddle.
Step Three: Dry Ingredients For This Custard Cream And White Chocolate Cookie Recipe
This cookie recipe keeps the dry ingredients in their own space for a reason, so everything blends evenly before it meets the wet mix. Flour, baking powder and bicarbonate come together first, forming the structure that will hold the cookie in shape as it bakes.
Sifting them with the custard powder helps everything fall through like soft dust, breaking up any lumps so the mix is light and even.
Once sifted, a quick whisk with a fork is enough just to distribute everything properly. You’re not trying to build anything here yet, just making sure the dry base is uniform and ready for the next stage without surprises.
Step Four: Folding The Cookies
When you first fold the dry ingredients into the wet mix, it will look dry and a bit wrong, like it’s refusing to become dough. You’ll still see flour streaks and crumbly patches, and the instinct will be to keep mixing until it looks smooth.
Don’t.
Stop there.
This is where the white chocolate and custard creams go in, and again, it will look like it’s not enough liquid, like everything is too dry to ever work.
That’s normal.
The dough should look slightly rough, thick and uneven at this stage, almost like it’s barely holding together.
The important part is here…
Do not over mix before or after adding the chocolate and custard creams.
Just fold gently until everything is roughly combined and then leave it alone. The oven will do the rest, turning that messy-looking dough into soft cookies with pockets of melted chocolate and crunchy biscuit pieces running through them.
Step Five: Chilling The Custard Cream & White Chocolate Cookie Recipe Before Baking
This custard cream cookie recipe really starts to settle when you let the dough rest. Once everything is mixed, it needs time to firm up, like butter cooling back into itself after being worked. This is what helps the cookies hold their shape instead of spreading into thin puddles in the oven.
I chilled mine for about an hour, nearly two, and that’s the sweet spot.
The dough goes from soft and sticky to firm and scoopable, almost like it’s calmed down and figured itself out.
Don’t rush this step, it’s what gives you thick cookies with structure and that bakery-style bite.
Step Six: Baking The Cookies
This white chocolate cookie recipe comes to life in the oven, where everything you’ve built turns into thick, golden cookies with melted white chocolate pockets and crisp edges.
Scoop the dough using an ice cream scoop so each cookie is the same size and shape. This keeps the bake even and helps them spread into those perfect bakery-style rounds rather than uneven blobs. Bake until the edges are golden, but the centres still look slightly soft, like they’re not quite finished yet.
Decorate with remaining custard creams and white chocolate chunks.
Bake in a preheated oven at 175°C for 10-12 minutes (check after 8 mins), keeping it to no more than five cookies per tray.
I did four to give them space to spread properly. They need room, like people standing too close at a crowded bar, they’ll push into each other if you don’t.
Step Seven: Let Them Cool
This white chocolate cookie recipe doesn’t finish when they come out of the oven, it finishes when you let them settle.
Straight from the tray, they’ll look too soft in the middle, almost like they’re underbaked, but that’s exactly what you want.
Leave them to cool on the tray for a few minutes so they firm up like butter setting back into place after heat. Moving them too early is like trying to pick up something still molten, they need that moment to hold their shape.
Once cooled slightly, they’ll have crisp edges, soft centres and those pockets of melted white chocolate fully set into gooey bites.
If You Need To Swap Or Spice Up This Custard Cream & White Chocolate Cookie Recipe!
This white chocolate cookie recipe is already built to hit that sweet spot between soft bakery cookie and nostalgic biscuit crunch, but it also gives you room to play without everything falling apart.
If you want a richer, less sweet cookie, swap some of the white chocolate for milk chocolate. It brings a deeper, almost caramel edge that balances the sweetness like a stronger brew cutting through a sugary biscuit.
If you want more crunch and structure, the easiest win is keeping the custard creams only as a topping instead of mixing them through the dough. Pressed on top before baking, they stay defined and give you that classic biscuit tin look without weakening the cookie structure inside.
You can also swap custard creams for other biscuits like digestives or shortbread if you want a different kind of crunch running through the bake. Digestives give a deeper, grainier bite while shortbread melts more delicately.
For a slightly more grown-up finish, a pinch of sea salt on top before baking completely changes the game. It sharpens the sweetness and makes the white chocolate taste even creamier, like everything suddenly switches into focus.
The base dough is your canvas here, and the biscuits and chocolate are just different ways of sketching on it.
Now let’s talk about how to store these cookies and freeze the dough so you can bake them fresh whenever you want.
Serving And Storing Your Custard Cream & White Chocolate Cookies
This white chocolate cookie recipe is at its absolute best when it’s still slightly warm from the oven, where the white chocolate is soft and glossy, almost like it’s just decided to turn into cream. The edges will have that gentle snap, while the centre stays soft enough that it gives way without effort.
If you’re serving them later, a quick 10–15 second warm-up in the microwave brings them right back to life. It’s like waking them up from a nap rather than reheating them, the chocolate loosens, the biscuit softens, and everything tastes freshly baked again.
For storing, keep them in an airtight container at room temperature for up to 4–5 days. They’ll stay soft, but the biscuit pieces will keep their bite, so you still get that custard cream crunch running through.
Now, the freezer part, because this is where most people get nervous. You can absolutely freeze both the baked cookies and the dough, and they don’t turn soggy if you do it properly.
For baked cookies, freeze them once fully cooled, layered with baking paper so they don’t stick together. To thaw, just leave them out at room temperature for an hour or so. No moisture, no sogginess, just a cookie coming back to itself.
For dough, shape it into balls first and freeze them solid. When you bake from frozen, just add a couple of extra minutes in the oven, and you’ll get that same thick, bakery-style result every time.
That’s the beauty of this white chocolate cookie recipe, it’s just as good planned ahead as it is eaten warm from the tray. Now let’s get into the full recipe card so you can bake them yourself.
