1-First Step: Preparation and Mise en Place Before you begin, line an 8×8-inch square baking pan with parchment paper, leaving some overhang on the sides for easy removal later. Gather all your ingredients and tools to make the process smooth. Have a microwave-safe bowl, a rubber spatula for mixing, and a separate bowl for the topping ingredients ready. Measure out all ingredients beforehand this technique, known as mise en place, prevents scrambling for items while hot ingredients are waiting.

2-Second Step: Creating the Chocolate Base In a microwave-safe bowl, combine 1 cup of chocolate chips and ½ cup of peanut butter. Microwave in 30-second intervals, stirring between each heating session. This prevents the chocolate from scorching and ensures even melting. Continue until the mixture is completely smooth and creamy. The stirring motion helps distribute heat evenly, so be patient and thorough during this step.

3-Third Step: Building the Fudge Mixture To your melted chocolate and peanut butter, add ¼ cup of softened cream cheese and the can of sweetened condensed milk. Stir these ingredients together until completely incorporated. The mixture should become thick and glossy. This combination is what gives the fudge its smooth, sliceable texture while still maintaining that creamy mouthfeel we love.

4-Fourth Step: Adding Texture Gently fold in 4 cups of Chex cereal, being careful not to crush the cereal pieces as you mix. You want to maintain that satisfying crunch in every bite. Next, stir in 2 cups of mini marshmallows they will soften slightly from the warmth of the chocolate mixture but still retain some structure, creating wonderful pockets of sweetness throughout the fudge.

5-Fifth Step: Pressing Into the Pan Transfer your mixture to the prepared 8×8-inch pan. Use the back of a spoon or your spatula to press the mixture firmly and evenly into the pan. This step is crucial for ensuring the fudge holds its shape when cut. Make sure the surface is as level as possible, which will help the top layer set evenly.

6-Sixth Step: Creating the White Chocolate Topping In a separate microwave-safe bowl, melt 1 cup of white chocolate with ½ cup of peanut butter using the same method as before microwave in 30-second intervals, stirring between each session. Once smooth and creamy, pour this mixture over the fudge base in the pan. Use a spatula to spread it evenly, creating a beautiful contrasting layer.

7-Final Step: Adding the Signature Puppy Chow Finish Dust the top generously with 2 cups of powdered sugar. This creates the classic puppy chow appearance and adds that signature sweet finish. Place the pan in the refrigerator and chill for at least 2 hours, or until completely firm. Once set, use the parchment paper overhang to lift the fudge from the pan, then cut into 16 equal squares. For clean cuts, wipe your knife between each slice or use a knife dipped in hot water. Your Puppy Chow Fudge is now ready to serve! Store any leftovers in an airtight container in the refrigerator for up to a week.
