Ingredients

• 1.5 cups All-purpose flour
• 0.5 cup Unsalted butter (cold, cubed)
• 0.25 cup Granulated sugar
• 2 Large eggs
• 1.5 cups Brown sugar (packed)
• 0.5 cup Unsalted butter (melted)
• 2 teaspoons Vanilla extract
• 1 teaspoon White vinegar
• 0.25 teaspoon Salt
• 0.5 cup Raisins (optional)
• 0.5 cup Pecans or walnuts (optional, chopped)

Directions

Step 1

Preheat your oven to 350°F (175°C). Grease and line an 8x8-inch baking pan with parchment paper, leaving some overhang to make removing the slice easier.

Step 2

In a medium bowl, combine 1.5 cups of all-purpose flour and 0.25 cup of granulated sugar. Add the 0.5 cup of cold, cubed unsalted butter and use a pastry cutter or your fingertips to blend until the mixture resembles coarse crumbs.

Step 3

Press the mixture evenly into the prepared baking dish to form the crust. Use the back of a spoon or your hands to pack it down firmly.

Step 4

Bake the crust in the preheated oven for 10–12 minutes, or until lightly golden. Remove and let it cool slightly while you prepare the filling.

Step 5

In a mixing bowl, whisk together 2 large eggs, 1.5 cups of packed brown sugar, 0.5 cup of melted unsalted butter, 2 teaspoons of vanilla extract, 1 teaspoon of white vinegar, and 0.25 teaspoon of salt until smooth and fully combined.

Step 6

If using raisins or nuts, sprinkle 0.5 cup of raisins and/or 0.5 cup of chopped pecans or walnuts evenly over the baked crust.

Step 7

Pour the filling mixture evenly over the crust (and toppings, if using). Spread gently with a spatula to ensure an even layer.

Step 8

Bake at 350°F (175°C) for 25–30 minutes, or until the filling is set and slightly browned around the edges. The center may still jiggle slightly but will firm up as it cools.

Step 9

Remove from the oven and allow the slice to cool completely in the pan on a wire rack. Then, use the parchment paper overhang to lift it out of the pan.

Step 10

Cut into 16 squares and serve. Store any leftovers in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 1 week.
