Butter Tart Squares

Golden, gooey, buttery, and filled with rich brown sugar flavor, Butter Tart Squares are a beloved Canadian-inspired dessert that combines a tender shortbread crust with a sweet caramel-like filling. These irresistible bars are easier to make than traditional butter tarts, yet they deliver the same comforting taste in every bite. Perfect for holidays, family gatherings, afternoon tea, or cozy evenings at home, these dessert squares are loved by both children and adults alike.

Introduction

Butter Tart Squares are the bar-cookie version of the famous Canadian butter tart. Instead of shaping individual pastry shells, the dessert is baked in layers inside one pan and sliced into neat squares. The result is a buttery shortbread base topped with a rich filling made from brown sugar, butter, eggs, and vanilla.

The filling becomes soft, sticky, and slightly chewy while the crust stays tender and crumbly. Some bakers love adding raisins, pecans, or walnuts for extra texture and flavor. Whether served warm or chilled, these squares melt beautifully in the mouth and leave a delicious caramel finish.

Ingredients

For the Shortbread Crust

  • 1 1/2 cups all-purpose flour
  • 1/2 cup powdered sugar
  • 1/2 cup unsalted butter, softened

For the Butter Tart Filling

  • 2 large eggs
  • 1 cup packed brown sugar
  • 1/4 cup unsalted butter, melted
  • 2 tablespoons all-purpose flour
  • 1 teaspoon vanilla extract
  • 1 tablespoon white vinegar
  • 1/2 cup raisins or chopped pecans (optional)

Equipment Needed

  • 8×8-inch baking pan
  • Mixing bowls
  • Hand mixer or whisk
  • Measuring cups and spoons
  • Rubber spatula
  • Cooling rack
  • Parchment paper

Instructions

Step 1: Prepare the Oven

Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking pan or line it with parchment paper for easier removal.

Step 2: Make the Crust

In a medium bowl:

  1. Combine the flour and powdered sugar.
  2. Add softened butter.
  3. Mix until the texture becomes crumbly like wet sand.

Press the mixture evenly into the bottom of the prepared pan.

Bake for 15 minutes until lightly golden around the edges.

Step 3: Prepare the Filling

While the crust bakes:

  1. Whisk together eggs and brown sugar until smooth.
  2. Add melted butter.
  3. Stir in flour, vanilla extract, and vinegar.
  4. Fold in raisins or pecans if desired.

The mixture should look glossy and silky.

Step 4: Assemble

Pour the filling over the warm crust evenly.

Use a spatula to spread gently into all corners.

Step 5: Bake Again

Return the pan to the oven and bake for 20–25 minutes.

The center should be set but slightly soft when gently shaken.

Do not overbake or the filling may become too firm.

Step 6: Cool and Slice

Allow the squares to cool completely before slicing.

For cleaner cuts:

  • Refrigerate for 30 minutes
  • Use a sharp knife
  • Wipe the blade between cuts

Methods and Baking Tips

Method 1: Classic Traditional Style

Use raisins for the classic Canadian butter tart flavor. The raisins absorb the buttery filling and become soft and sweet.

Method 2: Nut Lover’s Version

Replace raisins with chopped pecans or walnuts for added crunch and richness.

Method 3: Maple Butter Tart Squares

Add 2 tablespoons of maple syrup for a deeper Canadian-style flavor.

Method 4: Chocolate Twist

Sprinkle mini chocolate chips over the filling before baking.

The History of Butter Tarts

Butter tarts are considered one of Canada’s most iconic desserts. Their origins date back to the early 1900s in Ontario kitchens, where home bakers created simple desserts using pantry ingredients like butter, sugar, eggs, and pastry.

Over time, butter tart recipes evolved into many forms:

  • Traditional butter tarts
  • Nut-filled versions
  • Raisin butter tarts
  • Butter tart pies
  • Butter tart squares

Today, butter tart festivals are celebrated across parts of Canada, where bakers compete to create the best variation of this treasured dessert.

Formation and Texture

A perfect Butter Tart Square has three beautiful layers:

  1. Bottom Layer: Tender buttery shortbread crust
  2. Middle Layer: Gooey caramel-like butter tart filling

The contrast between the soft filling and crumbly crust creates the dessert’s signature texture.
