Instructions
- Preheat oven to 325°F (160°C). Grease and lightly flour a 9”x 13” baking pan.
- Whisk together the flour, baking soda, and salt. Set aside.
- Using an electric mixer on low speed, beat the butter and brown sugar until fluffy (about 2-3 minutes). Add the peanut butter and beat well. Mix in the egg and vanilla.
- Reduce mixer speed to low. Gradually add the dry ingredients and mix well. Stir in 1/2 cup chocolate chips, 1/4 cup white chocolate chips, 1/4 cup peanut butter chips, and pecans.
- Spread the mixture evenly into the prepared pan. Bake 25 to 30 minutes, or until lightly browned.
- Remove from the oven and sprinkle 1/4 cup chocolate chips and 1/4 cup peanut butter chips on top of the bars. Allow to sit for 1-2 minutes. Using a spatula, smooth out the chips as they begin to melt.
- Cool for 20 minutes. Sprinkle with the remaining 2 tablespoons each chocolate chips, white chocolate chips, and peanut butter chips. Cool completely before cutting into bars.
