Creating Butter Tart Squares is easy if you follow these simple steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C) and greasing an 8-inch square baking pan.

2. Make the Crust: In a mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. Add in the flour and salt, mixing until the dough comes together.

3. Press the Crust: Evenly press the dough into the bottom of the prepared baking pan. Make sure to smooth it out nicely across the base.

4. Bake the Crust: Place the crust in the preheated oven and bake for 15-20 minutes, or until lightly golden.

5. Prepare the Filling: While the crust is baking, combine the brown sugar, corn syrup, melted butter, eggs, vanilla extract, and salt in a mixing bowl. Stir until the mixture is smooth and creamy.

6. Add Any Extras: If you want, fold in nuts or raisins to the filling mixture.

7. Assemble: Once the crust is done, remove it from the oven and pour the filling over the hot crust.

8. Bake Again: Return the pan to the oven and bake for another 25-30 minutes, or until the filling is set and slightly puffed.

9. Cool Down: After baking, remove the pan from the oven and let it cool in the pan for about 15-20 minutes.

10. Slice and Serve: Once cool, cut into squares and enjoy!

Each step is designed to help you achieve the most satisfying Butter Tart Squares without fuss.
