Ingredients

Crust:

Filling:

  • 1 ¾ cups (350 g) light brown sugar
  • 1 cup (240 ml) light corn syrup
  • ½ cup (113 g) unsalted butter melted and cooled
  • 4 large eggs at room temperature
  • ¼ cup (30 g) all-purpose flour
  • 1 teaspoon pure vanilla extract
  • ½ teaspoon ground cinnamon
  • ½ teaspoon salt
  • ½ cup (100 g) raisins optional

Instructions

To Make the Crust:

  • Preheat the oven to 350°F (180°C), or 160°C if using a fan oven. Line a 9x13-inch (approx 22x33 cm) baking pan with parchment paper and set aside
  • In a large bowl, whisk together the flour, powdered sugar, and salt.
  • Pour in the melted butter and mix to combine, the dough will be thick and crumbly.
  • Press the mixture into the bottom of the prepared pan and bake in the preheated oven for 10 minutes, or until the crust is puffed a bit and starting to turn golden.
  • Remove from the oven and allow to cool slightly.

To Make the Filling:

  • Prepare the filling while the curst is baking. In a large bowl, whisk together the brown sugar, corn syrup, melted butter, eggs, flour, vanilla, cinnamon and salt until smooth.
  • Fold in the raisins if using.
  • Pour the filling into the prepared crust, then return to the oven to bake for 25-30 minutes, or until the filling is bubbling.
  • Remove from the oven and allow to cool. Chill in the fridge for easier slicing.

Notes

  • Plump the raisins: Let the dried raisins soak in boiling water for about 5 minutes before draining and adding them to the recipe. This isn't necessary, but does make the fruit extra juicy.
  • Other mix-ins: Instead of (or in addition to) the raisins, try adding other dried fruits such as currants or cranberries. For a less sweet butter tart filling, replace the raisins with chopped walnuts or pecans.
  • Adjust the flavor: This recipe calls for pure vanilla extract, but feel free to experiment with other flavor extracts like almond or rum extract here.
  • To Store: The best way to store these butter tart bars is to keep them in an airtight container in the fridge. They will stay fresh for up to 4 days this way.
