Toffee Espresso Blondies

  • ½ Cup (113g) Unsalted Butter, melted
  • 1 ¼ Cup (150g) All-Purpose Flour
  • 1 ½ Teaspoon Fine Espresso Powder
  • ½ Teaspoon Fine Salt
  • 1 Cup (200g) Light or Dark Brown Sugar, packed
  • 1 Whole Large Egg + 1 Large Yolk, room temperature
  • 1 Teaspoon Vanilla Paste or Extract
  • 4 Ounces (113g) Semi-Sweet or Dark Chocolate Bar, roughly chopped
  • ½ Cup (78g) Homemade Toffee Bits, or store-bought

Instructions

  1. Make Homemade Toffee Bits: In a small saucepan over medium heat, combine butter, brown sugar, and salt. Whisk often and cook until the mixture reaches 300°F (149°C) on a candy thermometer, about 8-10 minutes. If the mixture separates, remove from heat and whisk vigorously until combined again.
  2. Cool and Break Toffee: Pour the hot toffee mixture onto a small parchment-lined baking sheet. Spread thinly and let cool for 15 minutes. Once cooled, break into small pieces using the back of a spoon, rolling pin, or mallet. Set aside.
  3. Prep Oven and Pan: Place a rack in the center of the oven and preheat to 350ºF (176ºC). Butter and line an 8×8 inch (20×20 cm) square baking pan with parchment paper, leaving an overhang for easy removal. Set aside.
  4. Combine Butter and Sugar: Melt ½ cup (113g) unsalted butter. Transfer the melted butter to a large bowl, add 1 cup (200g) packed brown sugar, and whisk until smooth. Let cool slightly for 5 minutes.
  5. Mix Dry Ingredients: In a separate bowl, combine 1 ¼ cup (150g) all-purpose flour, 1 ½ teaspoons fine espresso powder, and ½ teaspoon fine salt. Set aside.
  6. Prep Chocolate: Roughly chop 4 ounces (113g) semi-sweet or dark chocolate and set aside.
  7. Combine Wet Ingredients: To the cooled butter and sugar mixture, add 1 whole large egg and 1 large yolk along with 1 teaspoon vanilla paste or extract. Whisk until fully emulsified.
  8. Add Dry Ingredients: Sift the dry ingredients into the wet mixture and gently mix until just combined with minimal flour streaks. Avoid over-mixing.
  9. Fold in Chocolate and Toffee Bits: Gently fold in the chopped chocolate and ½ cup (78g) of homemade toffee bits, reserving some for topping.
  10. Transfer and Bake: Pour the batter into the prepared pan, smoothing the surface. Sprinkle the reserved chocolate and toffee pieces on top. Bake for 20-24 minutes until edges are golden and center is shiny with a few moist crumbs on a toothpick test. Do not overbake.
  11. Cool and Serve: Cool the blondies completely in the pan on a wire rack for about 2 hours. Once cooled, sprinkle with flaky sea salt, cut into 16 (1-inch) pieces, and enjoy.
