Equipment

  • 8x8 or 9x9-inch square baking pan
  • Parchment paper
  • Mixing bowls (medium and large)
  • Electric hand mixer or stand mixer
  • Rubber spatula
  • Offset spatula or spoon
  • Fine-mesh sieve

Ingredients

For the Espresso Blondie Base:

  • 1 cup unsalted butter melted
  • 1 ½ cups light brown sugar packed
  • 2 large eggs
  • 1 tablespoon instant espresso powder
  • 1 teaspoon vanilla extract
  • 1 ¾ cups all-purpose flour
  • ½ teaspoon baking powder
  • ½ teaspoon salt

For the Mascarpone Cream Topping:

  • 8 ounces mascarpone cheese room temperature
  • ½ cup heavy cream
  • cup powdered sugar
  • 1 teaspoon vanilla extract
  • To Finish:
  • 1 tablespoon unsweetened cocoa powder for dusting

Instructions

Prepare the Pan and Preheat

  • Line pan with parchment and preheat oven to 350°F (175°C).
  • Tip: Use metal clips to secure the parchment.

Make the Blondie Batter

  • Whisk melted butter and brown sugar until glossy. Add eggs, espresso powder, and vanilla. Mix well.

Add Dry Ingredients

  • Sift in flour, baking powder, and salt. Gently fold until just combined.
  • Tip: Avoid overmixing for soft, chewy bars.

Bake

  • Spread into pan and bake 22–25 minutes. Edges should be golden; toothpick comes out with moist crumbs.

Cool

  • Cool completely in the pan. Refrigerate to speed up.
  • Tip: A cool base ensures the topping sets properly.

Whip the Cream Layer

  • Beat mascarpone, cream, powdered sugar, and vanilla until thick but soft.
  • Tip: Don’t overwhip — soft peaks are ideal.

Assemble

  • Spread topping over blondie. Smooth the surface. Chill 1–2 hours or overnight.

Finish

  • Dust with cocoa powder just before slicing into bars.
  • Tip: Wipe knife clean between cuts for sharp layers.
