The classic Canadian treat - Butter tarts but in bar form. Could it get any better? These Butter Tart Bars are ooey-gooey and everything you could ever want from a butter tart. The shortbread base is very similar to the flaky pastry and the sweet filling is almost identical but I actually like this version better than your regular butter tart.
If you're looking for that butter tart fix, you definitely need to try this and if you've never tried a butter tart then you definitely need to try this too!

Ingredients:
- All purpose flour
- Powdered sugar
- Salt
- Butter
- Brown sugar
- Eggs
- White vinegar
- Pure vanilla extract
Equipment:
- 9 x 13 pan
- Parchment paper
- Large bowl
- Pastry cutter
- Medium bowl
- Whisk
Instructions:
Line a 9×13" pan and line with parchment paper and spray with non stick spray. Preheat oven to 350 degrees F.
In a large bowl, combine flour and powdered sugar.
Cut butter into icing sugar and flour with a pastry cutter or your hands until pea-sized lumps of butter remain. When you grab a handful and squeeze, you want it to hold together. If it doesn't hold together, add 1-2 tablespoons of water.
Dump flour mixture into pan and press down evenly to form a crust. Bake for 10 minutes.
Meanwhile, prepare your filling. In a medium bowl, melt butter in the microwave. Whisk in brown sugar until smooth. Whisk in eggs, one at a time, then add the vinegar and vanilla.
Pour over crust and bake another 25-30 minutes until filling is set or almost set — a slight jiggle is fine but you don't want a lot of movement. Cool to room temperature and refrigerate several hours before slicing.
