gluten free blondie recipe

Daniel J. van Ackere


1 + 3/4 cups (8 ounces) ATK Gluten-Free All- Purpose Flour Blend
3/4 teaspoon salt
1/2 teaspoon baking powder
1/2 teaspoon xanthan gum
7 tablespoons unsalted butter, melted and cooled
1 cup packed light brown sugar
1/2 cup granulated sugar
2 large eggs
2 tablespoons milk
4 teaspoons pure vanilla extract
1/2 cup white chocolate chips
1/2 cup semisweet chocolate chips


1. Place oven rack in middle position and preheat oven to 325°F. Make a foil sling for an 8-inch square baking pan by folding 2 long sheets of aluminum foil so each is 8 inches wide. Lay sheets of foil in pan perpendicular to each other, with extra foil hanging over edges. Push foil into corners and up sides of pan, smoothing foil flush to pan. Spray with vegetable oil spray.

2. Whisk flour blend, salt, baking powder and xanthan gum together in bowl.

3. In large bowl, whisk melted butter, brown sugar and granulated sugar together until no lumps remain. Whisk in eggs, milk and vanilla until very smooth. Stir in flour mixture with rubber spatula until flour is completely incorporated and batter is homogeneous, about 1 minute. Fold in white chocolate and semisweet chocolate chips. Transfer batter to prepared pan and smooth top with spatula.

4. Place blondies in preheated oven and bake until deep golden brown and toothpick inserted in center comes out clean, 50 minutes to 1 hour, rotating pan halfway through baking.

5. Let blondies cool completely in pan on wire rack, about 2 hours. Using foil overhang, remove blondies from pan. Cut into 16 pieces and serve.
