These white chocolate espresso blondies are a sweet, rich, and chewy pick-me-up for any time of the day. Try these with your morning shot of espresso or heated up as an evening dessert served with ice cream.
Melt the butter over low heat and let cool. Preheat the oven to 350°F and line an 8x8-inch pan with parchment.
226 g unsalted butter
In a small bowl, whisk the flour, espresso powder, cornstarch, baking powder, and salt.
270 g all-purpose flour, 3 –4 tablespoon instant espresso powder, 1 Tbsp cornstarch, ½ tsp baking powder, 1 tsp salt
In a medium bowl, whisk together the cooled butter, brown sugar, cane sugar, eggs, egg yolk, and vanilla until combined.
200 g brown sugar, 100 g granulated, 2 large eggs + 1 egg yolk, 2 tsp vanilla extract
Whisk the dry ingredients into the wet until just combined.
Stir in the white chocolate chips, if using.
120 g white chocolate chips
Transfer the thick batter to the prepared pan and bake at 350°F for 30–40 minutes, until the center is just set. Cool before cutting.
Notes
For a softer interior, bake 25–30 minutes; for firm but chewy, 35–40. Pull them when the center is just set and barely jiggles.Line the pan with parchment so you can lift out the whole slab and cut clean squares.Store at room temperature 2–5 days, or freeze 3–6 months.
