Ingredients

Puffed Wheat Mixture

  • 10 cups toasted puffed wheat

Chocolate Sauce

  • 1 cup packed brown sugar
  • 2/3 cup unsalted butter
  • 2/3 cup golden or dark corn syrup
  • 1/4 to 1/2 cup Dutch process cocoa powder (1/4 cup for less intense chocolate, 1/2 cup for more chocolate flavor)

Marshmallows

  • 1 1/2 cups mini marshmallows (divided: 1 cup mixed in, 1/2 cup sprinkled on top)

For Greasing

  • Butter (for greasing baking dish and hands/spatula)

Instructions

  1. Prepare the baking dish: Grease a 9×13-inch baking dish well with butter and set aside to prevent sticking.
  2. Combine sauce ingredients: In a medium-large heavy-bottomed saucepan, mix 1 cup packed brown sugar, 2/3 cup unsalted butter, 2/3 cup corn syrup, and 1/4 to 1/2 cup Dutch process cocoa powder depending on your preferred chocolate intensity.
  3. Boil the sauce: Cook the chocolate mixture over medium-low heat, stirring occasionally until it reaches a rolling boil. Maintain the boil for exactly 60 seconds to develop the right consistency.
  4. Remove from heat and combine: Take the saucepan off the heat immediately after boiling, then pour the hot chocolate sauce over the 10 cups puffed wheat in a large bowl.
  5. Mix with marshmallows: Toss the puffed wheat thoroughly in the chocolate sauce until evenly coated, then add 1 cup of mini marshmallows and fold gently to combine.
  6. Press into baking dish: Transfer the coated puffed wheat mixture into the greased baking dish and press down firmly to compact. Use a buttered spatula or lightly buttered hands to avoid sticking while pressing evenly.
  7. Add marshmallow topping: Sprinkle the remaining 1/2 cup mini marshmallows evenly on top and allow them to soften and melt slightly before spreading if desired.
  8. Cool and set: Let the squares cool and set at room temperature for at least 60 minutes to firm up before slicing into squares for serving.

Notes

  • Adjust the cocoa powder to your taste preference: less for mild chocolate, more for richer flavor.
  • Use a buttered spatula or hands when pressing to prevent sticking and achieve a compact texture.
  • The squares need to cool fully to set properly; avoid refrigerating as it can harden the chocolate sauce excessively.
  • Store leftovers in an airtight container at room temperature for up to 3 days for optimal texture.
