Butter Tart Squares

There’s nothing more Canadian than butter tarts! They are a classic summer dessert and are made in many ways and varieties; like a thicker jelly-style filling or a runny gooey mess, with pecans, raisins or rich almost boozy-like filling! However you like it, there’s a butter tart out there for you!

I grew up with my grandma making the best butter tarts around. Light flaky pastry that fell apart in your hands, one bite and the runny, rich filling came spilling out. If you didn’t eat the butter tart quickly, the filling would leak out and slowly drip down your fingers. Messy but definitely worth it! Instead of making a mess, these butter tart squares are quick and easy to make, are more manageable, travel easily, and are a crowd pleaser just like the classic butter tart!

How To Make Butter Tart Squares

Step 1 – In a food processor add flour, sugar and butter. Pulse until the mixture is crumbly (you can also cut the butter into the flour mixture using 2 knives or using a pastry cutter). Pour the butter mixture into your prepared pan. Using the palm of your hand or the bottom of a glass press the mixture evenly into the pan.

Step 2 – Bake for 10–13 minutes or until the edges are lightly golden brown. Meanwhile, in a large mixing bowl beat the eggs and brown sugar until well incorporated and light and fluffy. Next, add the melted butter, vinegar, flour and vanilla, mix well. Add pecans or raisins if desired and mix in with a spoon. Pour over base and continue to bake for another 20–25 minutes or until set.

Step 3 – Let cool and cut into squares.

FAQ’s

What are butter tart squares?

Butter tart squares are very similar to butter tarts but are made with a shortbread crust instead of pastry and are made into bars or squares. The filling is rich and gooey just like butter tarts. They are simpler to make and to transport to picnics and backyard bbq’s.

Should you use light brown sugar or dark brown sugar for butter tart squares?

You can use either type of brown sugar to make your butter tart filling. The darker the sugar the richer the filling will be.

Can you freeze butter tart squares?

Butter tart squares freeze well. Simply add your squares pre-cut into an airtight container and freeze for up to 2 months. Let squares come down to room temperature before serving.

How do you know when butter tart squares are done?

The longer you bake your squares the thicker the filling and the crisper the crust will get. Since your shortbread is pre-baked the second bake time is mainly to set the filling. They are done when a slight crust develops on the top and when you jiggle the pan there isn’t any movement from the filling.

These squares were absolutely decadent but easy to make. You need to cut them into tiny pieces!! They looked great on a dessert platter with iced brownies for a backyard party.

Life is uncertain, but dessert doesn't have to be!
