1/2cupwhite chocolate chips, or 3 oz. chopped white chocolate
1 1/2Tbspmilk or half-n-half
Instructions
Preheat oven to 350 degrees. In a mixing bowl, whisk together flour, baking powder and salt, set aside. In a large mixing bowl, using an electric hand mixer, beat egg and egg yolks on medium speed until pale and fluffy, about 3-4 minutes. Add in sugar, butter, sour cream, lemon juice, lemon zest and vanilla, mix until well blended.
Add in dry ingredients and mix just until incorporated. Fold in blueberries. Pour mixture into a buttered 8x8 baking dish and spread into an even layer. Bake 30-34 minutes until toothpick inserted in center comes out with a few moist crumbs attached (I used chilled blueberries so mine took about 33 minutes).
Allow Blueberry Lemon Brownies to cool completely, then pour White Chocolate Glaze over top and spread evenly over brownies (I poured it in the center so it didn't all run down the sides of the bars, then I spread it out near the edges). Cut into squares (for cleaner cutting you can freeze bars for about 10-15 minutes to help glaze set before cutting).
White Chocolate Glaze
Combine all ingredients in a microwave safe bowl. Microwave mixture on 50% in 20 second intervals, stirring after each interval until melted and smooth.
