1-First, pour the 9 cups of Rice Chex cereal into a large bowl to create your base.

2-Next, combine the 2 cups of semisweet or bittersweet chocolate chips and ½ cup of creamy peanut butter in a microwave-safe bowl, then heat in 1-minute intervals, stirring between each until smooth and creamy, and stir in a pinch of coarse kosher salt.

3-Once melted, drizzle the chocolate mixture over the cereal and fold it together gently with a flat rubber spatula until everything is evenly coated.

4-Then, place the 1 ½ cups of dry brownie mix powder in a large bag, add the chocolate-coated cereal in batches, and shake vigorously until fully covered; or use a large container to layer and shake gently.

5-After coating, let the mixture cool completely on a flat surface.

6-Once cool, add the 4 cups of small pretzels and mix gently to incorporate that salty crunch.

7-Finally, store the finished Brownie Batter Puppy Chow covered at room temperature for several days, as it keeps well and stays fresh.
