Warm Gooey Home Made Brownies - MMMM!

My mom used to make home made brownies when I was growing up...I don't even think I saw her use a box mix. I loved them!! All warm, gooey, chocolatey - melt in your mouth goodness:) So I was excited to come across this yummy looking recipe and can't wait to try them...

Brownies from Amy’s Bread
Recipe from The Sweeter Side of Amy’s Bread.
3 & 1/3 cups (20 ounces) semisweet chocolate chips
1 cup unsalted butter
3 ounces unsweetened chocolate, chopped
1 cup granulated sugar
3 large eggs
1 tablespoon vanilla extract
1/2 cup + 1 tablespoon all-purpose flour
1 & 1/2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon kosher salt
1 & 3/4 cups chopped nuts, toasted (optional)
Preheat oven to 350°. Grease a 9″x 13″ baking pan. Line bottom of pan with parchment paper.
Melt butter, half of the chocolate chips, and unsweetened chocolate in a double boiler (or microwave). Let mixture cool to warm.
Whisk sugar, eggs, and vanilla just until mixed. Over-mixing will cause crumbly brownies. Fold in warm chocolate mixture.
Whisk flour, baking powder, baking soda, and salt. Fold dry ingredients into chocolate mixture until just combined. Stir in remaining chocolate chips and nuts (if using), mixing just until combined.
Pour batter into prepared pan. Spread to an even thickness. Bake 32-36 minutes. The edges will be slightly firm and the center will be soft when they are fully baked. Do not over bake. Cool completely in pan on wire rack.
Makes 12 large or 24 small brownies. These brownies may cut better if they are chilled first.
