Matcha Rice Krispie Treats

I had a lot of marshmallows leftover from my s’mores mochi donut recipe, so naturally, I was like let’s make matcha rice krispie treats! Rice krispie treats are one of my favorite desserts to make because they are just so easy and so good. These treats have a healthy dose of matcha powder and a little bit of black sesame seeds, so you get 2 really yummy flavors. And they’re also not that sweet! The matcha powder balances out the sweetness from the marshmallows really well.

Some details about key ingredients
- Matcha powder – Gives the Rice Krispie treats their green color and adds the matcha flavor. I like to use Aiya’s culinary grade matcha powder because the color and flavor hold the best out of all the matcha I’ve tried.
- Rice Krispie cereal – This is what makes this bar a Rice Krispie treat! Rice Krispie cereal has gluten in it, so if you want to make it gluten free, make sure to get the gluten free version. The brand does make it.
- Marshmallows – You can use either large or small marshmallows. I personally like to use small marshmallows because they melt faster and better.

Tips on how to make the perfect matcha rice krispie treats
Pre sift the matcha powder
Matcha tends to clump easily which prevents the rice krispie treats from having an even green color. So in order to reduce clumping, I sifted the matcha into a bowl before adding it to the melted marshmallows. I did this first because I found it too stressful to sift it while melting the marshmallows. This is a technique I use for almost all my matcha recipes.
Use high quality matcha
I mention this in a few of my previous matcha recipes like my crispy matcha cookies and matcha halva. High quality matcha makes your food greener and gives it a more intense matcha flavor. If you think you have lower quality matcha, I would highly recommend using more than 2 tablespoons of matcha powder.

This recipe is so easy and SO delicious! I was making it for our Hawai’i Girls Volleyball Team. I thought they may want it a tiny bit sweeter so I mixed in some semi-sweet chocolate chips at the end. Ohhh, my goodness! It turned out absolutely delicious! Thank you for sharing, Becca!
I love that you added chocolate chips! Makes them even better in my opinion! Thank you so much for making this recipe!
Hi Becca! Do you think I can add protein powder to this recipe?
I think you can, but am not sure how that would taste. Let me know if you try it!
Wanted to love this but it just didn’t work. There wasn’t enough Marshmallow so I feel like half of it was just dry unstuck cereal.
Thank you for trying the recipe! I’m sorry it didn’t work out for you
Just made these, so easy and delicious! I put 1.5 tbsp instead of 2 and it was perfect!
Yay! So glad you enjoyed them!
Is there a cooking step!? In the recipe it goes straight to “cool for ten minutes..”
You only need to cook the matcha marshmallow mixture. That is the “cooking” step. Once done, pour over the rice krispie treats. Mix and quickly press it into the pan. The rice krispie will harden as it cools.
