Deliciously thick and chewy blondies that are infused with vanilla, and stuffed full of salted caramel. These blondie bars are absolutely irresistible!
Preheat the oven to 180C/350F/Gas 4. Line an 8x8-inch square baking pan with parchment paper. Set aside.
In a large bowl, whisk together the butter and sugar until combined. Add the egg, egg yolk, and vanilla, and whisk until smooth and combined.
Add the flour and salt, and whisk until completely combined.
Spoon half of the batter into the prepared pan and spread out evenly.
For the Caramel Centre
Place the caramels and milk in a microwave-safe bowl, and heat in 30 second intervals, stirring after each one, until melted and smooth.
Allow to cool slightly and thicken up in the fridge - about 20 - 25 minutes.
Stir in the sea salt. Spread the caramel evenly over the blondie batter, then freeze until the caramel is firm - about 15 - 20 minutes.
Top with the remaining batter and spread out evenly.
Bake for 40 - 45 minutes or until the top is dry and golden. The centre will still be jiggly, but will firm up as the caramel layer cools.
Allow to cool completely in the pan on a wire rack before cutting into bars. For cleaner, neater slices, place the pan in the freezer for 1 hour before cutting.
Notes
Blondies can be stored in an airtight container at room temperature or in the fridge for up to 1 week. They also freeze well for up to 3 months. Thaw overnight in the fridge before serving.
