Green Rice Crispy Treats Recipe: Matcha-Infused Sweet and Crunchy Squares

This recipe transforms classic rice crispy treats with a vibrant green twist using matcha powder. The earthy tea flavor balances the sweetness beautifully.

You’ll get crispy edges, chewy centers, and a striking color that’s perfect for themed parties. No artificial dyes—just natural, delicious flavor.

Ingredients for Green Rice Crispy Treats

Eight simple ingredients. A vibrant green treat with earthy matcha magic.

The matcha powder is the star here—look for culinary grade at Whole Foods or Trader Joe’s. Avoid ceremonial grade (it’s pricier and too delicate for baking). I prefer Ippodo Tea or Jade Leaf brands for consistent color and flavor. The butter needs to be unsalted so you control the salt level. For marshmallows, Dandies are a great vegetarian option (gelatin-free).

No matcha? Green tea leaves finely ground work in a pinch, but the color won’t be as vibrant. Swap the rice cereal for puffed rice if that’s what you have. For a less sweet version, reduce marshmallows by 2 oz. The vanilla extract can be swapped for almond extract (use half the amount). Powdered sugar is optional but adds a nice finish.

These keep well in an airtight container at room temp for 4-5 days. For longer storage, freeze for up to 3 months—thaw at room temperature before serving. The matcha color stays bright if stored properly (don’t expose to direct sunlight).

Step-by-Step Instructions for Matcha-Infused Rice Crispy Treats

Here’s how to get that signature crispy texture while infusing vibrant matcha flavor throughout.

Step 1: Prepare the Pan and Measure Ingredients

Lightly grease an 8×8-inch baking pan with the 1 tsp Coconut Oil, making sure to coat the bottom and sides evenly. This prevents sticking and makes it easier to remove the treats later. I use a paper towel to spread it thinly and uniformly.

Measure out all your ingredients precisely—the 6 cups Crispy Rice Cereal, 10 oz Mini Marshmallows, 0.25 cup Unsalted Butter, 1.5 tbsp Matcha Powder, 1 tsp Vanilla Extract, and 0.25 tsp Sea Salt. Having everything ready to go ensures a smooth process with no frantic searching mid-recipe.

Step 2: Melt Butter and Toast Marshmallows

In a large, heavy-bottomed pot, melt the 0.25 cup Unsalted Butter over low heat. Once fully melted, add the 10 oz Mini Marshmallows and stir constantly with a silicone spatula. The marshmallows will start to soften and collapse after 3-4 minutes.

Keep stirring until the mixture is completely smooth with no visible marshmallow lumps. Be patient—if the heat is too high, the sugars can burn. You want a glossy, fully homogeneous mixture that coats the back of your spatula. Remove from heat immediately once achieved.

Step 3: Incorporate Matcha and Flavorings

Working quickly while the marshmallow mixture is still hot, stir in the 1.5 tbsp Matcha Powder, 1 tsp Vanilla Extract, and 0.25 tsp Sea Salt. The matcha will dissolve into the warm mixture, creating a vibrant green color and earthy aroma. Stir vigorously for 30-45 seconds to ensure even distribution.

The matcha should fully incorporate without clumping—if you see any dry spots, keep mixing. The vanilla adds depth, while the sea salt balances the sweetness. This step transforms your basic marshmallow mixture into something uniquely flavorful.

Step 4: Combine with Crispy Rice Cereal

Add all 6 cups Crispy Rice Cereal to the pot at once. Using your spatula, fold the cereal into the matcha marshmallow mixture gently but thoroughly. You want every piece of cereal coated in the green mixture, but avoid crushing the cereal—this preserves that essential crispy texture.

Stop mixing once the cereal is evenly coated and no dry spots remain. The mixture will look sticky and slightly glossy. If it seems too thick, you’ve likely overcooked the marshmallows slightly, but it will still set up properly once pressed into the pan.

Step 5: Press, Cool, and Finish

Transfer the mixture to your prepared pan. Using your spatula or the bottom of a measuring cup (lightly greased if needed), press the mixture evenly into the pan with firm, consistent pressure. This ensures the treats hold together and have a uniform texture.

Let the treats cool completely at room temperature for 30-45 minutes. Once set, use a sharp knife to cut into squares. For presentation, dust the tops lightly with 0.25 cup Powdered Sugar if desired. The result should be crispy on the outside with a slightly chewy center and vibrant matcha flavor throughout.

Dietary Considerations for This green rice crispy treats

Vegan Adaptation

Swap the 10 oz Mini Marshmallows for Dandies vegan marshmallows and use vegan butter like Miyoko’s or Earth Balance. The matcha flavor works perfectly with plant-based ingredients, and the texture remains just as crispy and chewy. 🌱

Gluten-Free Option

Use gluten-free crispy rice cereal like Nature’s Path Organic or Erewhon. Ensure all other ingredients, especially marshmallows, are certified gluten-free. The matcha adds a nice earthy contrast to the neutral cereal base.

Reduced Sugar

Cut the 10 oz marshmallows to 8 oz and add 1 tbsp chia seeds for fiber. The matcha’s bitterness balances the sweetness beautifully. The treats will be slightly less sticky but still hold together well.

Nut-Free Version

This recipe is naturally nut-free if you use standard ingredients. Always double-check marshmallow brands for cross-contamination warnings. Kraft Jet-Puffed marshmallows are a safe choice for nut allergies. 💡

Dairy-Free

Replace 0.25 cup Unsalted Butter with coconut oil or vegan butter. The matcha flavor pairs especially well with coconut, adding a subtle tropical note to the earthy green tea.

Lower Calorie

Use puffed rice cereal instead of crispy rice to reduce calories by about 20%. You can also reduce the marshmallows to 8 oz without sacrificing texture. The matcha provides rich flavor without added calories.
