Double Chocolate-Peanut Butter Chip Brownies

• 3 sticks ( 3/4 pound) unsalted butter, cut into tablespoons, plus more for greasing
• 3/4 pound semisweet or dark chocolate, finely chopped
• 3/4 cup plus 2 tablespoons white rice flour
• 3/4 cup tapioca flour
• 1/2 teaspoon kosher salt
• 6 large eggs
• 3 cups sugar
• 1 tablespoon pure vanilla extract
• 1 cup peanut butter chips
• 1/2 cup semisweet chocolate chips

1. Preheat the oven to 350.
2. Lightly grease a 9-by-13-inch metal baking pan.
3. Place the 3 sticks of butter in a heatproof bowl and set the bowl over a saucepan of simmering water (the bottom of the bowl should not touch the water).
4. Melt the butter, stirring occasionally.
5. Add the chopped chocolate and stir until melted.
6. Remove the bowl from the heat.
7. In a small bowl, whisk the rice flour with the tapioca flour and salt.
8. In a large bowl, whisk the eggs with the sugar and vanilla until blended.
9. Fold in the dry ingredients until incorporated, then fold in the peanut butter chips and chocolate chips.
10. Fold in the melted chocolate mixture.
11. Scrape the batter into the prepared dish.
12. Bake for about 1 hour and 15 minutes, until the brownies are slightly puffed and a tester inserted in the center of the brownies comes out with a few moist crumbs attached.
13. Transfer the pan to a rack and let cool completely before turning out the brownies and cutting them into bars.
