Ingredients You’ll Need

What makes Old School Butterscotch Tart truly nostalgic is its use of easy-to-find staples that, together, create something much greater than the sum of their parts. Every ingredient has a key role to play, whether it’s adding texture, flavor, or that unmistakable butterscotch hue.

• All-purpose flour: This forms the sturdy-yet-tender base for your tart; don’t skip the sifting for the flakiest results!
• Unsalted butter: Chilled for the pastry and melted for the filling, butter is the secret to both a crumbly shell and a silky, rich custard.
• Cold water: Just enough to bring the dough together—add gradually to avoid a sticky base.
• Pinch of salt: Elevates all the other flavors and keeps the sweetness in check.
• Light brown sugar: The heart of that classic butterscotch flavor and color—choose soft brown sugar for caramel notes.
• Whole milk: Keeps the filling creamy and lush without being too heavy.
• Vanilla extract: Rounds out the butterscotch flavor for a rich, fragrant finish.

How to Make Old School Butterscotch Tart

Step 1: Make the Pastry Base

Start by combining the flour and a pinch of salt in a bowl, then rub the chilled, cubed butter through the mixture with your fingertips. You’re aiming for a texture like coarse breadcrumbs—this helps the pastry stay crumbly and not tough. Slowly add cold water a tablespoon at a time, mixing gently until the dough just comes together. Don’t overwork it! Wrap the dough and let it chill; this step prevents shrinking and ensures a tender base for your Old School Butterscotch Tart.

Step 2: Pre-bake the Crust

Roll out your chilled dough on a floured surface, then carefully lift it into a tart tin. Press it in gently, trim any overhang and prick the bottom with a fork to keep it from puffing up in the oven. Bake in a preheated 350°F (175°C) oven for about 15–18 minutes until it turns lightly golden and the kitchen starts to smell irresistible. Cool the crust completely before adding your butterscotch filling.

Step 3: Prepare the Butterscotch Filling

Now, the magic happens! Melt butter and light brown sugar together in a saucepan over low heat, stirring until the sugar dissolves and the mixture turns glistening and caramel-colored. Sprinkle in the flour and whisk for a minute or two—this thickens your custard and gives it body. Gradually pour in the milk, whisking constantly, then let the mixture simmer until it thickens to a luscious, pudding-like consistency. Take off the heat and stir in vanilla for that signature aroma. Marvel at how the kitchen smells exactly like the school canteen of your dreams.

Step 4: Assemble

Pour the glossy butterscotch filling into your cooled tart shell, smoothing the top with a spatula. Now comes the most challenging part: the wait. Chill the tart in the fridge for 2–3 hours, or until it’s completely set and easy to slice. The patience is worth it—Old School Butterscotch Tart gets creamier and more flavorful as it chills!

Step 5: Serve

Once set, remove from the tin and slice into generous wedges. For extra pizazz, sprinkle a pinch of flaky sea salt over the top. Enjoy every soft, decadent mouthful of your homemade Old School Butterscotch Tart!

How to Serve Old School Butterscotch Tart

Garnishes

This tart is a looker on its own, but a sprinkle of sea salt, a dusting of icing sugar, or some delicate chocolate shavings can really make it pop. For a retro twist, scatter a few toasted pecans or caramel shards for crunch.

Side Dishes

A scoop of vanilla ice cream, a dollop of clotted cream, or even a spoonful of whipped cream pairs beautifully with Old School Butterscotch Tart. If you want to go extra nostalgic, a spoonful of custard served warm alongside really hits the mark.

Creative Ways to Present

Try slicing the tart into mini squares for a dessert table, or serve individual tartlets for a posh afternoon tea. You can get playful with plating—add edible flowers or serve with a drizzle of caramel sauce for a modern, restaurant-worthy look.

Make Ahead and Storage

Storing Leftovers

Old School Butterscotch Tart keeps well in the fridge, tightly covered, for up to four days. The filling stays silky, and the flavors deepen beautifully—making leftovers (if you have any) even more delicious the next day.

Freezing

To freeze, wrap slices tightly in plastic wrap and foil, then freeze for up to two months. Thaw overnight in the fridge—just know the texture may become a shade softer, but the flavor will still be nostalgic and comforting.

Reheating

If you prefer the tart slightly warm, gently heat individual slices in the microwave for 10–15 seconds. The filling will loosen up a bit, almost pudding-like, which some say makes Old School Butterscotch Tart even better!

FAQs

Can I use store-bought pastry instead of homemade?

Absolutely! If you’re short on time, ready-made shortcrust pastry works just fine. You’ll still get that classic Old School Butterscotch Tart flavor with a lot less fuss.

What if I don’t have light brown sugar?

No worries—you can use dark brown sugar for a deeper molasses flavor, but keep in mind the tart will turn out a shade darker and a bit richer in taste.

How do I know when the butterscotch filling has thickened enough?

The filling should coat the back of a spoon and look luxuriously glossy. Once it cools, it will set even more. Don’t wait until it’s super thick in the pan, or it might become too stiff after chilling.

Can I make Old School Butterscotch Tart ahead of time?

Yes, and it’s actually better that way! Prepare the whole tart a day in advance, keep it in the fridge, and it will slice beautifully and keep its creamy texture.

Is there an easy way to get slices out neatly?

Make sure the tart is fully set and use a sharp, warm knife (dip it in hot water, then dry) for extra-clean slices. Running the knife along the edges before lifting helps too!

Final Thoughts

There’s nothing quite like the simple, nostalgic joy of slicing into an Old School Butterscotch Tart.
