Start by taking a large bowl and adding the crispy rice cereal squares. Set this aside for now; we'll come back to it shortly.
In a saucepan over low heat, melt the butter and semi-sweet chocolate chips. Stir them gently until they create a smooth mixture. The aroma of melting chocolate is simply delightful!
Once melted, add the peanut butter to the pan. Mix it in thoroughly until everything is well combined and smooth. If it seems a bit thick, don’t hesitate to raise the heat slightly but keep it low to avoid burning.
If you prefer the microwave, you can also microwave the chocolate chips, peanut butter, and butter together in a large bowl. Start with one minute on high, then stir, and keep microwaving in 30-second intervals until it’s all melted and smooth.
Stir in the vanilla extract until the mixture is evenly blended. This step adds a wonderful depth to the flavor!
Now, pour the melted chocolate mixture over the bowl of crispy rice cereal. Using a spatula, gently stir everything together until the cereal is well coated, ensuring no dry pieces remain.
Once mixed, transfer the coated cereal into a large resealable food storage plastic bag. This makes it easy to coat everything with the powdered sugar.
Next, add the confectioners’ sugar into the bag, seal it tightly, and shake it vigorously. This step is not just fun; it ensures that every piece is evenly coated.
Spread the mixture onto waxed paper to cool completely. This cooling step is crucial as it allows the chocolate to harden.
After it has cooled down completely, mix in the M&Ms and mini peanut butter cups. Gently stir to combine, being careful not to break any of the cereal pieces.
Store your Reindeer Chow in an airtight container. It can last for several days, but I doubt it will stick around that long!
