Blondies With A Strawberry Balsamic Swirl Recipes

Steps:

• Preheat the oven to 350 degrees F. Line an 8-inch-square baking pan with foil, pressing it into the corners and up the sides; leave an overhang on 2 sides. Butter the foil.
• Put 4 tablespoons butter and the brown sugar in a large microwave-safe bowl. Microwave until the butter is melted, about 1 minute. Stir in the vanilla. Let cool slightly, then stir in the egg.
• Whisk the flour, salt and baking powder in a small bowl. Stir into the butter mixture. Stir in the butterscotch chips and nuts and spread the batter in the pan. Drop dollops of jam on top and swirl with a knife. Bake until set, 20 to 25 minutes. Let cool 15 minutes on a rack, then lift the foil and transfer the blondies to the rack to cool completely. Remove the foil and cut into bars.

Steps:

• Roast white chocolate: Heat oven to 300 degrees. Spread white chocolate on a rimmed baking sheet and bake for about 10 minutes. Remove from oven and stir with a spatula until browned chocolate at edges is evenly mixed with uncooked chocolate in center. Once stirred, chocolate should be the color of dark peanut butter. If it isn't, continue to bake in 5-minute increments to darken. Watch closely: White chocolate can easily burn. Let cool.
• Make blondie batter: Lightly coat a 9x13-inch metal baking pan with butter. Line it with parchment paper so there is a 2-inch overhang on the pan's long sides. Place a clean, empty baking sheet in the oven, and increase the temperature to 350 degrees.
• Place butter and both sugars in the bowl of a stand mixer fitted with the paddle attachment. Beat together on medium speed until light and creamy, about 2 minutes. Add vanilla and salt and beat to incorporate. Add eggs one at a time, beating after each addition to incorporate completely and scraping down the sides of the bowl. Add oil and beat. Scrape roasted white chocolate into bowl (it may have hardened and gotten a little grainy: This is O.K.) and mix it in. Add flour and mix on low speed until absorbed. Scrape batter into the prepared pan.
• Make strawberry-balsamic swirl: Place strawberries and sugar in a small saucepan over medium heat. Cook, stirring frequently with a wooden spoon and smashing the berries, until they release their juices and fall apart, 10 to 12 minutes. Separately, stir cornstarch and a tablespoon of water and drizzle it onto strawberries, continuing to stir for a minute or two until mixture has thickened into jam. Continue cooking for 2 more minutes, stirring constantly, then remove from heat. Stir in balsamic vinegar. Drop generous tablespoons of strawberry mixture over batter and use a butter knife to swirl them together, but don't overmix.
• Place pan on baking sheet in oven. Bake until blondies are golden brown and a toothpick inserted into the center comes out clean, 25 to 35 minutes. They will firm up as they cool, so pull them out 2 or 3 minutes before your desired consistency. Place pan on a wire rack and, once room temperature, remove blondies from pan by pulling on parchment paper. Transfer to a cutting board, cut into squares, and serve.
