1-First Step: Mise en Place Measure out all ingredients ahead. Line your 8×8-inch pan with parchment paper, leaving overhangs for lifting. Crush 2 cups Rice Chex cereal into small pieces using a zip-top bag and rolling pin. This prep keeps everything moving smoothly, especially for busy professionals or college students.

2-Second Step: Melt the Base In a large microwave-safe glass bowl, combine 2 cups semi-sweet chocolate chips, 1 cup creamy peanut butter, and 1/2 cup unsalted butter. Microwave in 30-second bursts, stirring after each until fully melted and smooth, about 2 minutes total. Stir vigorously to avoid hot spots. For dietary tweaks, use vegan alternatives here; they melt just as well.

3-Third Step: Mix in Dry Ingredients Sift 4 cups powdered sugar into the melted mixture to prevent lumps. Add 1 teaspoon vanilla extract. Stir with a sturdy spoon or electric mixer on low until creamy and thick, like frosting. If too stiff, microwave 10 seconds more. This step builds the fudgy texture central to your no bake fudge.

4-Fourth Step: Layer the Fudge Spread half the fudge mixture evenly into the prepared pan using a spatula. Sprinkle 2 cups crushed Chex over the top, pressing lightly. Pour and spread the remaining fudge on top, covering the cereal completely. For extra flair, mix in 1/2 cup mini chocolate chips to the top layer. Pat down gently for even layers. Gluten-free? Rice Chex works perfectly here.

5-Fifth Step: Chill and Set Refrigerate the pan uncovered for 2-4 hours until firm to the touch. No need to cover initially to avoid condensation. Test by pressing the center; it should spring back. This chilling mimics baking without heat, ideal for apartment dwellers.

6-Final Step: Cut and Serve Lift fudge from the pan using parchment. Cut into 36 even 1.5-inch squares with a sharp knife dipped in hot water for clean edges. Dust tops with extra powdered sugar if desired. Serve at room temperature for best flavor. Store leftovers as detailed later. Pro tip: For low-calorie versions, portion smaller squares. This easy no bake puppy chow fudge impresses every time.
