British mint custard is a nostalgic treat that instantly transports many back to the comforting days of British school dinners, where simple dishes delivered unforgettable flavour. This pale green, mint-infused twist on traditional English custard adds a refreshing, creamy contrast to hearty puddings like chocolate sponge or jam roly poly. Unlike the classic yellow or pink custards, this version carries a cool peppermint note that makes it both familiar and unique. In this guide, you’ll learn what mint custard is made of, how to recreate it authentically at home, and why it holds such a beloved place in British dessert history. Whether you’re revisiting a favourite or trying it for the first time, British mint custard is your gateway to the timeless joy of old-school puddings.
A trip down the school dinner lane
Hello, my dears! The moment I start whisking custard in a saucepan, I’m transported straight back to my school days in Yorkshire. Among the hearty trays of sponge and puddings, one dessert was always a favourite: British mint custard.
It wasn’t just the light green hue or the creamy texture. It was the gentle hit of peppermint, warm and soothing, poured over something indulgent like old school chocolate sponge cake. We’d line up eagerly, metal trays in hand, secretly hoping for seconds if the dinner lady was feeling kind.
It was a simple joy, a scoop of cake, a ladle of minty custard, and somehow, that combination made a dreary afternoon feel a little more special. When I made it recently for my grandchildren, they were skeptical. But one bite in, and their eyes lit up. “Why don’t they make this anymore?” they asked. Exactly.
British mint custard as a cultural gem
In post-war Britain, school kitchens relied on pantry staples that were economical yet comforting. Custard powder, milk, and peppermint essence were easy to store and stretch, and the result was magic. British mint custard became a beloved finish to many a traybake or steamed pudding.
Though less common today, there’s a beautiful revival happening. Just like British pink custard and British yellow custard, mint custard is returning to the home cook’s repertoire. And if you’ve ever enjoyed a slice of cornflake tart, you know exactly what it deserves on top.
What Is British Mint Custard Made Of?
Simple ingredients with nostalgic flavour
The first time you tasted British mint custard, you likely didn’t stop to ask what was in it, you just knew it was smooth, creamy, and delightfully minty. Like so many cherished school dinner puddings, its magic comes from simplicity. No fancy ingredients or modern tricks here, just the basics found in nearly every British kitchen for generations. As The Guardian’s guide to making proper custard shows, the foundation of good custard is humble, and mint custard is no exception.
Here’s what you’ll need to make authentic British mint custard:
| Ingredient | Quantity | Purpose |
|---|---|---|
| Custard powder | 2 tablespoons | Forms the base; thickens when heated |
| Sugar | 2 tablespoons (granulated) | Adds the essential sweetness |
| Whole milk | 500 ml | Gives richness and smooth texture |
| Peppermint extract | ¼ to ½ teaspoon | Provides that signature mint flavour |
| Green food colouring (optional) | 1–2 drops | Gives it the nostalgic pastel-green hue |
The mint extract is the star, of course. Just a small amount transforms ordinary custard into something bright and memorable. A little green food colouring helps bring back that school dinner aesthetic, but it’s entirely optional if you prefer to keep things natural.
If you enjoy recipes like chocolate concrete or old school jam roly poly, this mint custard will feel right at home.
How it’s different from classic custard
You might be wondering: isn’t all custard basically the same? Not quite. Traditional English custard (or “yellow custard” as many know it) is a simple, vanilla-flavoured sauce, either made with eggs and cream or the shortcut, custard powder and milk.
Mint custard keeps the base the same but swaps the vanilla for peppermint, giving it a much fresher taste. It’s less rich than British chocolate custard and more vibrant than its vanilla cousin.
Here’s a quick side-by-side:
| Classic Custard | British Mint Custard |
|---|---|
| Flavoured with vanilla | Flavoured with peppermint |
| Pale yellow or cream in colour | Pastel green (with food colouring) |
| Often served with sponges or pies | Perfect with chocolate or jam-based puddings |
It’s this contrast, cool mint against warm pudding, that made mint custard so popular in British school kitchens.
How to Make Traditional British Mint Custard at Home
Step-by-step recipe preparation
Making British mint custard at home is surprisingly easy and incredibly satisfying. This version uses custard powder, just like the old school kitchens did, but with a fresh twist of peppermint that takes it from simple to nostalgic perfection.
Step 1.
In a small bowl, mix custard powder and sugar with a few tablespoons of cold milk to form a smooth paste. Stir well to avoid lumps.
Step 2.
Heat the rest of the milk in a saucepan over medium heat until it begins to steam, but not boil. Stir gently to keep it from catching.
Step 3.
Pour the custard paste into the warm milk while whisking continuously. Keep the mixture moving to prevent clumps and ensure a silky finish.
Step 4.
Continue cooking the custard over low to medium heat, stirring constantly, until it thickens to your desired consistency. It should coat the back of a spoon smoothly.
Step 5.
Remove from heat and stir in peppermint extract. Start with a few drops and taste, you can always add more, but you can’t take it out.
Step 6.
If you want that classic school dinner look, add a drop or two of green food colouring and stir until the colour is evenly distributed.
Step 7.
Pour over your favourite warm dessert and serve immediately.

Serving ideas from British tables
British mint custard was often ladled generously over dense puddings that needed a sweet, silky lift. It pairs beautifully with chocolate sponge, sticky traybakes, or jam-soaked puddings. The mint cuts through richness and brings everything together.
At home, you can try it over:
- Chocolate sponge (just like in school)
- Jam roly poly
- Coconut and jam cake
- Cornflake tart (another school dinner favourite)
You can also serve it on its own in little bowls for the kids, topped with sprinkles or a flake for a fun after-dinner treat. Warm, cooling, smooth, and sweet, it’s a dessert sauce that stands proudly on its own.
FAQs Answered & Fun Facts
What is mint custard made of?
British mint custard is made from custard powder, sugar, whole milk, peppermint extract, and sometimes a touch of green food colouring. It’s a simple blend, but the mint flavour gives it a distinct identity that sets it apart from vanilla or chocolate varieties. This nostalgic twist became a school pudding staple for decades.
What is English custard made of?
Traditional English custard is typically made from milk, egg yolks, and sugar, thickened gently over heat to create a creamy pouring sauce. However, most homes and schools in the UK used custard powder (like Bird’s), which contains cornflour and colouring. This powdered version is what gives British yellow custard its iconic taste and texture.
Is mint custard a thing?
It absolutely is, though it’s less commonly found today, mint custard was a real highlight of British school dinners in the 60s through the 90s. It’s still loved by those who remember it and is now enjoying a quiet comeback through home cooks and nostalgic blogs like ours.
What is custard called in the UK?
In the UK, custard is simply called “custard.” The term usually refers to a warm, sweet sauce served with desserts, not the set version used in some tarts. When Brits talk about custard, they typically mean the pouring kind made from powder or eggs.
What do British people eat with custard?
Custard is one of the most versatile dessert sauces in Britain. It’s often served with sponges, puddings, crumbles, or tarts. Dishes like classic jam roly poly, chocolate sponge, or Manchester tart all benefit from a generous pour of warm custard, mint or otherwise.
Is custard healthy or unhealthy?
Custard is best enjoyed as a treat. While it provides calcium from milk, it also contains sugar and in some traditional versions, egg yolks. The powdered version is typically lower in fat but still high in carbohydrates. For a lighter version, you can use skimmed milk and less sugar.
Modern spins & dietary tweaks
While the classic British mint custard remains a nostalgic favourite, there’s still plenty of room to make it your own. For a dairy-free version, swap in oat or almond milk, just be sure to choose one with a neutral taste to keep the custard smooth and clean. If you’re aiming for a lighter take, reduce the sugar or leave out the green food colouring entirely, especially when serving children.
