My girls and I weren’t always Harry Potter fans. It wasn’t until I visited the Harry Potter Studios Tour in London that I fell in love with the wizarding world. I came home and introduced it to my oldest daughter, who was nine at the time, and she was hooked immediately. That’s when we officially became a Harry Potter family.

These days, I may be a little obsessed with this amazing recipe book I was gifted recently. The Unofficial Hogwarts Cookbook For Kids is packed with all the best desserts from the Harry Potter Series, including these little Pumpkin Pasties, colorful Acid Pops, and the second most popular drink at Hogwarts, Pumpkin Juice.

There are so many Harry Potter recipes to choose from. But if you’re looking for great way to impress even the most die hard fans (like my girls), there’s no better option than Harry’s favorite dessert.

What is a Traditional Treacle Tart

A traditional British dessert, a treacle tart starts with a tender and flaky pie crust. It’s also famously known as Harry Potter’s favorite dessert! You pre-bake the crust in a tart tin until golden brown, then fill it with a sticky toffee pudding-like filling and bake to perfection.

Since I’m working through recipes from The Unofficial Hogwarts Cookbook For Kids, this recipe uses molasses (also known as black treacle), along with eggs and fresh bread crumbs. The egg yolks help give the tart filling a thick custard like consistency.

Most traditional recipes all for golden syrup (light treacle) instead, which has a sweeter, buttery caramel flavor. Molasses has a stronger, richer toffee like taste. If you’d rather have a sweeter tart, you can swap in golden syrup instead.

How To Make This Easy Treacle Tart Recipe

For the crust

Step 1: Preheat the oven temperature to 350 °F.

Step 2: In the bowl of a stand mixer fitted with the paddle attachment, or in a large mixing bowl using a hand mixer, cream the butter and sugar together until light and fluffy.

Step 3: On low speed, add the flour a little at a time until just combined.

Step 4: Press the uncooked pastry dough into a 9-inch tart pan with a removable bottom. Use a fork to gently prick the crust all over the bottom.

Step 5: Chill the crust for 15 minutes in the freezer. Then bake for 15-20 minutes until light brown and let cool to room temperature.

For the filling

Step 1: To make the filling, whisk together the melted butter, milk, eggs, lemon zest, lemon juice and molasses in a large bowl. Continue until well combined.

Step 2: Fold in bread crumbs until thoroughly coated with the syrup mixture.

Step 3: Pour the filling into the prepared crust. Place the tart back in the oven for an additional 20 minutes, or until the pastry is golden brown.

Step 4: Remove from heat and let cool for at least 20 minutes before slicing with a sharp knife. Serve with ice cream or a generous dollop whipped cream on top.

Wrap leftovers tightly in plastic wrap and store for up to a week in the refrigerator.

Tips And Variations

• If the dough sticks to your hands while pressing it into the tart pan, dip your fingers in a little cold water, shaking off the access water. The coldness should help the dough release.
• While baking, if the pastry edges begin to brown too much, loosely tint the tart with foil or use a pie crust edge guard.
• If your pie crust seems little crumbly, adding really cold water, one teaspoon at a time, to the dough may help make it more solid.
• If you’re feeling a little fancy, you can make extra pastry dough to create a lattice top.
• Make this tart with a little bit of a pecan pie flair. Add about 1/4 cup finely chopped pecans to the liquid filling before baking.
• Prefer a sweeter tart? Swap the molasses for golden syrup (light treacle) for a milder, buttery caramel flavor instead of a deep toffee one.

This easy Harry Potter Treacle Tart is such a sweet and decadent treat. Like most British desserts, it goes perfectly with a cup of afternoon tea or hot coffee.

My favorite way to serve it, though, is with a glass of Harry Potter Butterbeer! I hope you love this tart as much as we do.
