Butter Tart Squares Recipe

Introduction

Butter Tart Squares are a delightful twist on the classic Canadian treat, combining a buttery shortbread crust with a rich, gooey filling. These bars are perfect for dessert or a sweet snack, offering a wonderful balance of sweet and nutty flavors.

Ingredients

• 1 cup unsalted butter (softened)
• 1/2 cup powdered sugar
• 2 1/4 cups all-purpose flour
• 1/2 cup unsalted butter (softened)
• 1 cup brown sugar (light or dark)
• 2 tablespoons all-purpose flour
• 4 large eggs
• 2 teaspoons vanilla extract
• 3/4 cup dark corn syrup
• 2 tablespoons white vinegar
• 1 cup raisins, currants or chopped walnuts (optional; recommended 1/2 cup currants and 1/2 cup chopped walnuts)

Instructions

1. Step 1: Preheat the oven to 350°F. Line a baking pan with parchment paper, leaving an overhang around the edges for easy removal.
2. Step 2: In a large bowl, beat 1 cup softened butter and powdered sugar until fluffy. Mix in 2 1/4 cups flour until the mixture is thick.
3. Step 3: Press the dough evenly into the bottom of the prepared pan. Bake for 15-20 minutes, or until the top is set and pale golden. Keep the oven on after removing.
4. Step 4: While the crust bakes, prepare the filling. Beat 1/2 cup softened butter, brown sugar, and 2 tablespoons flour until smooth.
5. Step 5: Add eggs and vanilla extract to the butter mixture and beat until combined.
6. Step 6: Stir in dark corn syrup and white vinegar. Fold in optional raisins, currants, or chopped walnuts if using.
7. Step 7: Pour the filling over the warm crust and return the pan to the oven. Bake for 30-35 minutes until the top is set and the filling is no longer liquidy when gently nudged.
8. Step 8: Remove from the oven and let cool completely before slicing to ensure clean cuts and set bars.
9. Step 9: Use the parchment paper overhang to lift the bars out of the pan. If edges are too crispy, slice them off before cutting into squares with a sharp knife.

Tips & Variations

• Substitute raisins or currants with chopped dates or dried cherries for a different fruity flavor.
• Use toasted pecans or almonds instead of walnuts for added crunch and richness.
• Allow the bars to cool fully or chill briefly to make slicing easier and prevent the filling from sticking.

Storage

Store butter tart squares in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze for up to 3 months. Reheat briefly in a warm oven to soften if desired.

FAQs

Can I make these squares gluten-free?

Yes, you can substitute the all-purpose flour with a gluten-free flour blend that measures cup-for-cup. Make sure it contains xanthan gum for structure.

Can I omit the raisins, currants, or nuts?

Absolutely. The filling is delicious on its own, but adding dried fruit or nuts gives extra texture and flavor if desired.
