Preheat the oven to 350 degrees and generously grease a 9x13 inch pan, or line it with a sheet of parchment paper.

In a large mixing bowl, whisk together the melted butter and both sugars until smooth. (You can also do this in your stand mixer or using an electric mixer)

Whisk in the eggs, milk, vanilla and almond extract until smooth.

Next mix in the remaining dry ingredients, flour and salt into the wet mixture.

Fold in the chopped pistachios and 6 oz small white chocolate chunks.

Using a rubber spatula, pour the blondie batter into the prepared pan.

Spread the blondie mix into an even layer and bake for 25-27 minutes.

Remove from oven and let them cool on a wire rack.

In a small saucepan over low heat, melt the remaining white chocolate. You can also do this in the microwave in 20 second increments.

Drizzle the melted white chocolate over the top of the blondies, and then sprinkle on some extra chopped pistachios.

Let the melted chocolate set, and then cut into small pieces or squares.
