Traditional Canadian Butter Tarts Variations
This recipe is inspired by traditional Canadian Butter Tarts. However, making them is much easier by turning those tasty tart treats into bite-sized squares.
The traditional butter tart is a tart consisting of butter, sugar, syrup, and egg baked into a small pastry shell. What makes the butter tart so delicious is the sweet bottom, gooey center, and semi-solid crunchy top.
As a Canadian expat, traditional Butter Tarts are still one of my favorites treats to make. However, they can be time consuming with having to make individualized pastry shells and, personally, sometimes too sweet with the only sugar-based filling.
The variations that exist for this tart include adding raisins, walnuts, and/or pecans. Around the Thanksgiving, I like to make the traditional tarts, but add in pecans to give it an almost mini pecan pie feel.
For these squares, I have added raisins and walnuts to give the traditional butter tart a chewy texture which slightly calms the sweetness from the tart. Even better the whole recipe is made in a 9 x 9 inch baking dish so there is no need to form individual tartlets.
How to Make Butter Tart Squares
There are only two layers to the squares, although it may look like more because of the top. That’s what so great about these bars! They get a slightly crunchy top to cover that gooey middle.
Firstly, you need to make the bottom layer. This is a simple shortbread layer involving flour, brown sugar, and chilled cubed butter that you have to cut into the dough.
There are a couple of ways you could cut the butter into the dough. Pictured above is a traditional pastry cutter / dough blender that you use to cut the butter up and mix it with the flour and sugar. If you don’t have one of these, you could always cut it in using two butter knives (although it takes longer, this option does work!) Alternatively, you could put the ingredients in a food processor and pulse just until the butter is less than pea-sized and incorporated with the rest of the mixture.
Next, press the mixture into the bottom of an ungreased 9 x 9 baking pan. Bake for 10 minutes until just set.
Secondly, to make the filling you will need to cream together the brown sugar and eggs until frothy. This is an essential step and really gives the butter tart squares the puffed and chewy center. You can use a hand mixer or whisk for this step. Beat until the eggs and sugar are incorporated and the mixture looks lighter in color.
Butter Tart Squares with Raisins and Walnuts
Lastly, fold in the remaining ingredients, including the walnuts and raisins. You could substitute pecans for the walnuts or golden raisins if you like. Additionally, you could leave the raisins and walnuts out altogether and make a more traditional version of the Canadian butter tart.
Pour on top of the baked shortbread layer and return to oven for about 25-30 minutes or until just set in the center.
Cool the squares on a wire rack completely before cutting, if you can wait that long! You could also pop these in the fridge. I like to cut my squares into small pieces, which is why I say you can get 36 squares from this recipe.
