Easiest Brownies in the World

1 12-ounce bag chocolate chips (use the kind you prefer)
1 cup butter (2 sticks)
1 1/2 cups sugar
4 large eggs at room temperature
1 1/2 cups flour

Preheat oven to 350 degrees. In a medium saucepan over low heat, melt butter and chocolate chips. Stir constantly and remove from heat when chips are fully melted. In the same pot, use a mixer and blend in the sugar. Then add eggs, blending fully one at a time. Add flour and beat until air bubbles form in the batter. Pour into a greased 9 X 13-inch pan (this recipe works great doubled and poured into a large 11 X 17-inch rimmed baking sheet). Bake for 20 minutes. Turn heat down to 325 degrees and bake for 10 more minutes.
