For those who prefer a less sweet option, consider reducing the amount of brown sugar or using a sugar substitute. You can also adjust the filling's texture by blending the ingredients longer for a smoother consistency or leaving it a bit chunky for added texture. The possibilities are endless, making this recipe a perfect canvas for your creativity.

Ingredients

For the crust

  • 1 cup all-purpose flour
  • 1/2 cup unsalted butter, softened
  • 1/4 cup powdered sugar
  • 1/4 teaspoon salt

For the filling

  • 1 cup brown sugar, packed
  • 1/2 cup corn syrup
  • 1/4 cup unsalted butter, melted
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup raisins (optional)

Combine all ingredients according to the recipe steps for the best results.

Instructions

Preheat the oven

Preheat your oven to 350°F (175°C) and grease a square baking pan.

Make the crust

In a bowl, mix together flour, softened butter, powdered sugar, and salt until crumbly. Press the mixture into the bottom of the prepared baking pan.

Prepare the filling

In another bowl, whisk together brown sugar, corn syrup, melted butter, eggs, and vanilla extract until smooth. Stir in raisins if using.

Bake the squares

Pour the filling over the crust and bake for 25 minutes or until the filling is set. Let it cool completely before cutting into squares.

Allow the squares to cool completely for the best texture before serving.

Storage Tips

To keep your Butter Tart Squares fresh and delicious, store them in an airtight container at room temperature for up to five days. If you want to extend their shelf life, consider refrigerating them, where they can last for about a week. Just be sure to allow them to come to room temperature before serving, as the flavors are best when enjoyed slightly warmed.

For longer storage, you can freeze these squares. Wrap them individually in plastic wrap and place them in a freezer-safe container. They can be frozen for up to three months. When you're ready to enjoy them, simply thaw in the refrigerator overnight or let them sit at room temperature for a few hours.

Serving Suggestions

Butter Tart Squares can be enjoyed on their own, but they also pair wonderfully with a variety of accompaniments. A dollop of whipped cream or a scoop of vanilla ice cream on the side can elevate this treat to new heights of indulgence. For a richer flavor, drizzle caramel sauce or chocolate syrup over the top for an added touch of decadence.

Consider serving these squares alongside a robust cup of coffee or a sweet dessert wine to enhance the flavors. The contrast between the rich sweetness of the squares and the bitterness of coffee or the fruity notes of wine makes for a delightful tasting experience.
