What Are Butter Tart Squares?
Before we get into the recipe, let’s define what makes Butter Tart Squares stand out.
Butter Tart Squares are essentially a simplified version of butter tarts. These squares have a shortbread crust topped with a sweet, gooey filling made primarily from brown sugar, butter, eggs, and vanilla. You can also add raisins for extra texture, although they are optional. The result is a decadent, melt-in-your-mouth treat that is rich in flavor but surprisingly easy to make.
Unlike traditional butter tarts, which require you to prepare individual tart shells, Butter Tart Squares allow you to bake everything in a 9×13-inch pan, saving you time and effort while still delivering that beloved buttery flavor. They are cut into squares after baking, making them a more convenient and mess-free version of the classic tart.

The Essential Ingredients for Butter Tart Squares
To create the best Butter Tart Squares, you’ll need to have the right ingredients. Here’s a breakdown of what you’ll need and what each component brings to the table:
- All-purpose flour – This forms the base of your shortbread crust. It gives the crust its structure and texture.
- Powdered sugar – Adds sweetness to the crust while making it more delicate and melt-in-your-mouth.
- Unsalted butter – The star of the recipe, butter adds richness to both the crust and the filling. Use cold, cubed butter for the best results when making the crust.
- Brown sugar – This is the main sweetener for the filling, giving the squares their signature caramel-like sweetness.
- Eggs – Eggs help bind the filling together, making it thick and gooey once baked.
- Vanilla extract – For added flavor and depth in the filling.
- White vinegar – A traditional ingredient in butter tarts, the vinegar helps balance out the sweetness of the sugar, giving the filling a more complex flavor profile. (Note: You can adjust or omit this if preferred.)
- Raisins (optional) – For those who like a chewy element, raisins are a great addition, but they’re totally optional.
Tools You’ll Need:
- 9×13-inch baking pan – This is the ideal size to bake your squares, ensuring the right thickness for both the crust and the filling.
- Mixing bowls – For combining the crust ingredients and the filling ingredients.
- Pastry cutter or hands – To mix the butter into the flour for the crust, creating the perfect crumbly texture.
- Whisk – To beat the eggs and mix the filling ingredients until smooth.

Step-by-Step Guide to Making Butter Tart Squares
Now that you know the key ingredients, let’s walk through the process of making these delightful squares. Follow this simple recipe to create a batch of Butter Tart Squares that will have everyone coming back for more.
Prep Time: 15 minutes
Cook Time: 30 minutes
Total Time: 45 minutes
Servings: 36 squares
For the Crust:
- Prepare the Pan: Start by lining a 9×13-inch baking pan with parchment paper, ensuring it hangs over the edges for easy removal. Lightly spray the paper with non-stick spray to prevent sticking.
- Mix the Crust: In a large bowl, combine the flour and powdered sugar. Add the cold, cubed butter. Use a pastry cutter or your hands to work the butter into the flour mixture until it forms pea-sized crumbs. If the mixture doesn’t hold together when you squeeze it, add a tablespoon of cold water, one at a time, until it does.
- Press the Crust into the Pan: Dump the crumbly mixture into the prepared pan and press it down evenly to form the crust. Bake in a preheated oven at 350°F (175°C) for 10 minutes. While it bakes, prepare the filling.
For the Filling:
- Melt the Butter: In a medium bowl, melt the butter in the microwave. Once melted, whisk in the brown sugar until the mixture is smooth.
- Add the Eggs: Add the eggs, one at a time, whisking after each addition. This ensures the eggs are fully incorporated into the filling.
- Flavor the Filling: Stir in the vanilla extract and white vinegar. If you’re using raisins, now’s the time to add them in.
- Pour the Filling: Once the crust is done baking, remove it from the oven and pour the filling evenly over the hot crust.
- Bake the Squares: Return the pan to the oven and bake for 25-30 minutes, or until the filling is set with only a slight jiggle in the center. Be careful not to over-bake—over-baking can lead to a dry, crumbly filling.
- Cool and Slice: Allow the squares to cool to room temperature, then refrigerate them for a few hours to help them firm up. Once chilled, cut into squares and enjoy!

Pro Tips for Perfect Butter Tart Squares
- Watch the Bake Time: For gooey squares, it’s important not to over-bake the filling. It should be set but still slightly wobbly in the center.
- Chill Before Cutting: Allowing the squares to cool and chill before cutting helps the filling set and makes them easier to slice into neat squares.
- Customize the Filling: Feel free to add nuts, such as pecans or walnuts, for a delightful crunch. Or experiment with flavored extracts like maple or rum for an extra twist.
Storing and Freezing Your Butter Tart Squares
Once you’ve made your Butter Tart Squares, you might find yourself with a lot of leftovers (or maybe not!). No worries—these squares store well, and there are ways to keep them fresh for later. Here’s how to properly store and even freeze your Butter Tart Squares for future enjoyment.
How to Store Butter Tart Squares
- Room Temperature: If you’re planning to eat your Butter Tart Squares within a few days, store them at room temperature. Simply place them in an airtight container or cover them tightly with plastic wrap. They’ll stay fresh for up to 3 days.
- Refrigeration: To make them last longer, refrigerate your Butter Tart Squares. Place them in an airtight container to prevent them from drying out. These squares will keep well in the fridge for up to 1 week, allowing you to enjoy them at your leisure.
Freezing Butter Tart Squares
If you want to keep your Butter Tart Squares for an extended period, freezing them is a great option. Here’s how to do it properly:
- Cool Completely: Make sure your Butter Tart Squares are completely cooled before freezing them. This prevents condensation from forming inside the container, which could cause them to become soggy.
- Layering for Freezing: Place your squares in an airtight container or freezer bag. If you’re stacking the squares, place wax paper or parchment paper between the layers to prevent them from sticking together.
- Freeze for Up to 3 Months: Butter Tart Squares freeze beautifully and can be stored for up to 3 months. When you’re ready to enjoy them, simply remove them from the freezer and let them thaw at room temperature for 20-30 minutes.
- Quick Thaw Option: If you’re in a hurry, you can eat them straight out of the freezer. They’re still delicious when slightly frozen, making them a great treat for those moments when you need a quick sweet snack.
Variations of Butter Tart Squares: Making Them Your Own
One of the best things about Butter Tart Squares is how easy it is to make them your own. You can tweak the recipe to suit your taste preferences or to give it a unique twist. Here are some ideas to make your Butter Tart Squares stand out:
1. Add Nuts for Crunch
Adding chopped pecans, walnuts, or even almonds can give your Butter Tart Squares a delightful crunch. These nuts pair beautifully with the caramelized filling and buttery crust.
2. Go Maple
Maple syrup is a beloved Canadian flavor, and it can add a rich, aromatic twist to your Butter Tart Squares. Swap out the white vinegar for maple syrup to deepen the flavor and give the squares a more authentic Canadian taste.
3. Add Chocolate
For a decadent, indulgent twist, try adding chocolate chips or chunks to the filling. The sweetness of the brown sugar and butter combined with the richness of chocolate creates an irresistible flavor combination.
4. Raisins or No Raisins?
The addition of raisins is a classic choice, but feel free to skip them if they aren’t your favorite. Some people love the chewy texture they add, while others prefer a smooth, gooey filling without the fruit. It’s all about what you enjoy most!
5. Experiment with Flavors
If you’re feeling adventurous, you can experiment with different extracts, like rum, almond, or even a touch of cinnamon, to elevate the flavor profile of your Butter Tart Squares. A small amount can go a long way in enhancing the overall taste of the filling.

FAQs on Butter Tart Squares
Q: Can I use salted butter for the crust?
A: It’s best to use unsalted butter for both the crust and the filling, as it gives you more control over the level of saltiness in the final product. If you only have salted butter, just skip any additional salt in the recipe.
Q: Can I make Butter Tart Squares gluten-free?
A: Yes, you can easily make gluten-free Butter Tart Squares by using a gluten-free all-purpose flour blend in place of the regular flour. Just ensure your other ingredients are also gluten-free (such as the powdered sugar and vanilla extract).
Q: What’s the best way to cut Butter Tart Squares neatly?
A: To cut Butter Tart Squares neatly, it helps to let them cool completely and refrigerate them for a few hours. Use a sharp knife to cut them into even squares. If the knife becomes sticky, wipe it clean between cuts.
Q: Can I add coconut to the filling?
A: Yes! Adding shredded coconut is a fun variation that adds texture and flavor. It pairs beautifully with the caramelized filling and gives the squares an extra chewy bite.
