Chocolate Chip Cookie Dough Fudge

Place flour in a medium-size microwaveable bowl. Microwave on HIGH, stirring at 30-second intervals, until flour is hot, about 30 seconds to 1 1/2 minutes. Let cool slightly, about 5 minutes.

Beat butter, sugar, and vanilla in a large bowl with an electric mixer on medium-high speed until fluffy, about 3 minutes. With mixer on low speed, beat in cooled flour until combined, about 1 minute.

Combine sweetened condensed milk and melted white chocolate in a large bowl. Fold in butter mixture and 1/2 cup of the semisweet chocolate chips. Place in a parchment paper-lined, lightly greased (with cooking spray) 8-inch square baking pan, smoothing top with a spatula. Sprinkle with remaining 1/4 cup semisweet chocolate chips. Refrigerate until firm, about 2 hours. Cut into pieces, and serve. Store in an airtight container in refrigerator for up to 4 days.
