These Easy Baseball Diamond Rice Krispies Treats are a quick, fun, and nostalgic snack perfect for game day celebrations. They combine the classic sweet, crunchy Rice Krispies base with playful baseball diamond decorations.

Ingredients

Scale
  • 6 cups Rice Krispies cereal (or your favorite crispy rice cereal)
  • 3 tablespoons unsalted butter, softened
  • 1 package (10 oz / about 40) mini marshmallows (or 4 cups regular marshmallows melted down)
  • White royal icing or store-bought white icing (for the diamond lines)
  • Red gel icing or red decorating gel (to mark the bases and outline the baseball stitches)
  • Optional: edible glitter or white sanding sugar (adds a fun sparkle)

Instructions

  1. Lightly grease an 8×8-inch baking pan or line it with parchment paper for easy removal.
  2. In a large microwave-safe bowl or saucepan, melt 3 tablespoons of unsalted butter over low heat or in 30-second bursts in the microwave, watching closely to avoid browning.
  3. Stir in the entire package of mini marshmallows to the melted butter. Continue heating and stirring every 15 seconds until the marshmallows are completely melted and smooth.
  4. Immediately add 6 cups of Rice Krispies cereal to the marshmallow mixture. Use a spatula or buttered wooden spoon to gently fold and mix until every crisp is coated evenly. Avoid overmixing.
  5. Transfer the mixture to your prepared pan. Using a buttered spatula or wax paper, gently press the mixture evenly into the pan without pressing too hard.
  6. Let the pan sit at room temperature for at least 30 minutes to firm up. Optionally, refrigerate for 15 minutes to speed cooling.
  7. Once set, carefully remove the block from the pan. Using a sharp knife, cut into a large diamond shape (rotated square), then slice smaller squares inside to resemble bases.
  8. Using white icing, pipe lines to outline the diamond and base paths. Use red decorating gel for the bases and stitching details on the ‘baseball.’ Optionally, sprinkle edible glitter. Let icing set for about 15 minutes before serving.

Notes

Butter your hands or spatula to prevent sticking when pressing the mixture. Let treats cool fully before cutting and decorating to avoid melting icing. Use a sharp knife dipped in hot water for clean cuts. Mini marshmallows melt faster and smoother than regular marshmallows.
