Ingredients for butter tart cookie
Buttery dough, golden syrup, and foil-sealed magic—here's what you'll need for perfect butter tarts every time.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for dough |
| Granulated Sugar 🍚 | ½ cup | White or light brown |
| Golden Syrup 🍯 | ½ cup | Or light corn syrup |
| Large Eggs 🥚 | 1 whole | Room temperature |
| Vanilla Extract 🌿 | 1 tsp | Pure vanilla preferred |
| Sea Salt 🧂 | ½ tsp | Fine grain preferred |
| Raisins 🍇 | 1 cup | Plump, soaked optional |
| Aluminum Foil 📄 | 1 sheet | Heavy-duty preferred |
| Dark Brown Sugar 🍚 | ½ cup | Packed, for filling |
| Light Corn Syrup 🍯 | ¼ cup | If no golden syrup |
| Heavy Cream 🥛 | ¼ cup | Cold, for filling |
The butter is non-negotiable—European-style or Plugrá is ideal for that rich flavor. Grab it cold from Whole Foods or the dairy case at Trader Joe's—it makes all the difference. Golden syrup? British imports like Trebor or Keiller are worth hunting down, but light corn syrup works in a pinch. Raisins should be plump and moist—if yours look dry, soak them in warm water for 10 minutes. For the foil, heavy-duty is key—it needs to seal tight during baking. I always double-check the foil's freshness; old foil can tear and ruin the seal.
No golden syrup? Light corn syrup plus a splash of molasses mimics that caramel depth. Swap raisins for chopped dates or dried cranberries if you prefer. The dough can handle 1 tbsp sour cream if you want extra tenderness, but trust me on the full-fat butter—it's what creates that legendary crunch. For a tangy twist, add 1 tsp lemon zest to the filling. And if you're feeling fancy, toasted pecans on top add crunch. Just don't skip the foil—it's the secret weapon for that gooey center.
Dough keeps for 4 days in the fridge wrapped tightly, or 3 months frozen between parchment. The filling? Mix it up the day you bake—it's best fresh. Once baked, these stay crisp for 2 days at room temp in an airtight container. For holidays, I make a triple batch and freeze the unbaked dough cups—just add filling and bake straight from frozen. Pro tip: Store filled dough cups in the freezer for up to 2 weeks before baking. The foil-sealed technique makes them reheat beautifully—just 10 seconds in the microwave to revive that molten magic.

Step-by-step instructions for foil-sealed butter tarts
Here's how to create the perfect balance of crispy crust and gooey caramel centers—every time.
Prepare the Tart Dough
In a large mixing bowl, combine the 2.5 cups all-purpose flour, 0.5 teaspoon sea salt, and 0.5 cup granulated sugar. Whisk lightly to distribute the ingredients evenly—this prevents dense pockets in your cookies. Cut in the 1 cup cold unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces. This texture is crucial for achieving that signature crunch.
Add the 1 whole large egg and 1 teaspoon vanilla extract, mixing just until the dough comes together. Avoid overworking the dough—it should hold when pressed but still feel slightly shaggy. Divide the dough into 4 equal portions (about 4 ounces each) and flatten into discs. Wrap each in plastic wrap and chill for at least 30 minutes (up to 24 hours). Chilling firms up the butter, ensuring crispy edges when baked.
Make the Caramel Filling
In a medium saucepan, combine the 0.5 cup dark brown sugar, 0.25 cup light corn syrup, and 0.25 cup heavy cream. Stir over medium heat until the mixture reaches a gentle boil, then reduce heat to low and simmer for 3-4 minutes, stirring occasionally. The filling should thicken slightly but remain pourable—this ensures it creates those signature rivers when baked.
Remove from heat and stir in the 1 cup raisins. Let the mixture cool for 5 minutes while you prepare the baking sheets. If using golden syrup instead of light corn syrup, the filling will have a deeper, richer flavor—worth the extra effort for true authenticity.
Assemble and Seal the Tarts
Preheat your oven to 375°F and line a baking sheet with parchment paper. Unwrap one chilled dough disc and roll it between two sheets of parchment paper into a 6-inch circle (about ⅛-inch thick). Place the circle on the prepared baking sheet and use a 3-inch round cutter to cut out 4 tart shells, re-rolling the scraps for additional shells if needed.
Spoon 1 tablespoon of caramel filling into each shell, leaving room at the top. Fold a 3-inch square of aluminum foil in half to create a crease, then fold it again to make a small triangle. Place the foil triangle on top of each tart, pressing gently to seal the edges. This foil seal is what creates those irresistible caramel rivers when baked.
Bake to Golden Perfection
Bake the tarts on the middle rack for 12-15 minutes, until the edges are golden brown and the foil begins to puff slightly. Rotate the baking sheet halfway through for even baking. The foil will create steam, which helps the filling bubble and create those beautiful rivers when you remove it.
Remove the tarts from the oven and carefully peel back the foil. Return them to the oven for 1-2 minutes to let the caramel set slightly. Let them cool on the baking sheet for 5 minutes before transferring to a wire rack. The centers should still be soft and gooey, with crisp edges that contrast perfectly against the creamy filling.
Pro Tips For Making Butter Tart Cookie
- CHILL THE DOUGH: After mixing the butter, sugar, and golden syrup into the flour, wrap the dough in plastic and refrigerate for at least 2 hours—overnight works even better. I used to skip this and ended up with flat, greasy cookies that spread like pancakes. Cold dough holds its shape and develops better flavor.
- MELT THE BUTTER SLOW: When creaming the butter and sugar, use room-temperature butter (not melted) and mix on medium speed until light and fluffy—about 3-4 minutes. I learned this the hard way after overmixing and ending up with dense, tough cookies. Let the mixer do the work here.
- WEIGH THE FLOUR: Spoon the flour into the measuring cup, then level it off with a knife—don’t scoop directly from the bag. Golden syrup is sticky, and too much flour makes the cookies dry. I now weigh mine (120g for this recipe) to avoid guesswork.
- ADD EGGS ONE AT A TIME: Beat the first egg into the dough until fully incorporated, then add the second. Stop mixing as soon as the dough comes together—overworking it introduces air, which causes flat cookies. I was skeptical until I tried it, and now it’s non-negotiable.
Flavor customization for these flavors
Classic Raisin Twist
Keep the traditional raisin filling but boost the flavor by tossing them in 1 teaspoon warm rum or orange liqueur before adding to the caramel. This adds a subtle boozy depth that pairs perfectly with the buttery crust.
For extra richness, fold in 2 tablespoons chopped pecans—they add crunch while balancing the gooey raisins. 🍯
Spiced Caramel Version
Infuse the caramel filling with warm spices by adding ½ teaspoon ground cinnamon, ¼ teaspoon cayenne pepper, and ¼ teaspoon freshly grated nutmeg while simmering.
The spices caramelize beautifully, creating a complex flavor profile that’s both sweet and slightly spicy. Swap raisins for chopped dried apricots to complement the spices.
Salted Caramel Upgrade
Take the classic filling to the next level by finishing it with a pinch of flaky sea salt (like Maldon) while still warm. The salt cuts through the sweetness, enhancing the caramel’s depth.
For an extra touch, sprinkle toasted flaked sea salt on top of each tart after baking. This technique is inspired by Canadian butter tarts, where salt is a key flavor enhancer. ✨
Chocolate-Dipped Variation
After baking, let the tarts cool slightly, then dip the bottom half into melted dark chocolate (use 70% cocoa for balance). Place them on parchment paper to set, then drizzle with extra melted chocolate.
This adds a sophisticated twist while keeping the classic butter tart experience intact. Store in an airtight container to maintain crispness.
Nut-Free Option
For a nut-free version, replace raisins with chopped dried cherries or diced dates (pitted and chopped). The natural sweetness of cherries adds a tart contrast, while dates provide a chewy texture.
If you prefer fruit, dried cranberries (unsweetened) work beautifully too. This keeps the filling cohesive without relying on nuts or raisins.
Vegan Adaptation
Use vegan butter (like Miyoko’s) and flax eggs (1 tablespoon ground flaxseed + 3 tablespoons water per egg) to make the dough. For the filling, substitute heavy cream with coconut cream (chilled overnight) and use agave syrup** instead of golden syrup.
The texture will be slightly denser but still delicious, with a subtle coconut note that complements the caramel. 🌱

Frequently asked questions
Why do I need to use foil for these butter tarts?
The foil creates an airtight seal that traps steam during baking, which transforms the filling into those signature molten rivers. Without it, you'll get a flat, dry caramel instead of the gooey center everyone loves. The steam also helps the crust crisp up perfectly—it's the secret weapon behind this recipe's texture magic!
Can I make these without raisins?
Swap raisins for chopped dried cherries, dates, or even pecans if you prefer. For a fruit-free version, try toasted coconut flakes or white chocolate chips—just adjust the amount to 1 cup total to maintain the filling's consistency. The key is keeping the texture contrast with the crisp crust.
How do I fix runny filling after baking?
If your filling is too liquidy, it likely didn't set properly. Return the baked tarts to 350°F for 2-3 minutes to thicken the caramel. For next time, ensure your filling reaches a soft-ball stage (when dropped from a spoon, it forms a ball that flattens slightly) before baking. Chilling the filling for 10 minutes after mixing also helps.
Can I use this dough for other desserts?
Yes! This versatile dough works perfectly for mini cheesecakes (press into muffin tins), hand pies (fill with fruit), or even cinnamon rolls. The high butter content gives everything a rich, flaky texture. Just reduce baking times by 20-30% since it's thinner than traditional pastry dough.
How long can I store the unbaked dough?
The dough stays fresh for 4 days in the fridge wrapped tightly, or 3 months frozen between parchment. For best results, freeze in 1-ounce discs (about 4 per quart bag) to make thawing easier. Let it thaw in the fridge overnight before rolling—never at room temperature to prevent soggy dough.
