Friday night, I made a bunch of mini malted milk cookie tarts  for a Bake Sale for Japan  and had some malted milk powder and Whoppers leftover. I immediately thought of the Brewer’s Blondies recipe in the Baked cookbook that I flagged the first time I skimmed the book and knew they had to be made.
The blondies are buttery, rich, and not too sweet. I cut the Whoppers into quarters and they gave the blondies a little bit of texture which was nice. I didn’t find the malted flavor very noticeable, but that may be because I ate salt and vinegar Pop Chips before I tried the blondies and my taste buds were dead. However, I brought the bars into the office today and received a ton of compliments on them. Apparently they make a very good breakfast.
2 1/3 cups all-purpose flour
1 1/2 teaspoons baking powder
1 teaspoon salt
2 tablespoons malted milk powder
14 tablespoons unsalted butter, softened, cut into 1-inch cubes
1 3/4 cups firmly packed dark brown sugar
2 large eggs
2 teaspoons pure vanilla extract
3/4 cup malted milk balls (like Whoppers or Maltesers), coarsely chopped in a food processor
3/4 cup semisweet chocolate chips
Preheat the oven to 350 degrees F. Butter the bottom and sides of a 9-by-13-inch baking pan.
In a medium bowl, whisk the flour, baking powder, salt and malted milk powder together.
In the bowl of an electric mixer fitted with the paddle attachment, beat the butter and brown sugar on medium speed until completely combined. Scrape down the bowl, add the eggs and vanilla, and beat until combined.
Add the flour mixture in two batches until just combined. Add the malted milk balls and chocolate chips and beat until just combined, about 10 seconds. The mixture will be thick. Turn the mixture out into the prepared pan and use an offset spatula to spread it evenly.
Bake in the center of the oven for 25 to 30 minutes, or until a toothpick inserted into the center of the blondie comes out clean.
Transfer to a wire rack and let cool for 20 minutes.
