Soft, thick, and chewy Vanilla Chai Blondies made in one bowl with warm chai spice and plenty of vanilla. These spiced dessert bars have crackly tops, fudgy centers, and taste like a spiced vanilla latte you can slice.
Preheat the oven to 325°F. Line an 8x8 metal pan with parchment paper, leaving an overhang for easy lifting.
Whisk 10 tablespoons cooled melted butter, 1 1/4 cups brown sugar, and 1/4 cup granulated sugar until thick and glossy.
Add 2 large eggs, 1 egg yolk, and 1 tablespoon vanilla, then whisk until the mixture ribbons off the whisk.
Stir in 2 1/2 to 3 teaspoons chai spice.
Fold in 1 3/4 cups flour, 1/2 teaspoon baking powder, and 1/2 teaspoon salt until just combined. The batter will be thick.
Spread the batter evenly into the prepared pan.
Bake for 28 to 33 minutes, until the edges are set and the center still has a soft jiggle.
Cool completely in the pan before slicing for the best fudgy, chewy texture.
Whisk the butter and sugar until glossy for those crackly tops, and pull the blondies while the center still jiggles slightly for a fudgy middle.
Start with 2 1/2 teaspoons of chai spice and add more to taste. Fresh homemade chai spice gives the best flavor.
