Key Ingredients
For the cookies:
- 1 cup peanut butter: Smooth or crunchy, depending on your preference.
- 1/2 cup brown sugar: For sweetness and moisture.
- 1/4 cup granulated sugar: Adds sweetness and helps with texture.
- 1 large egg: To bind the ingredients together.
- 1 teaspoon vanilla extract: For flavor enhancement.
- 1 teaspoon baking soda: Helps the cookies rise.
- 1 tablespoon matcha powder: For flavor and color.
For the mochi filling:
- 1 cup mochiko (sweet rice flour): The main ingredient for making mochi.
- 1/2 cup water: Needed to make the mochi dough.
- 2 tablespoons granulated sugar: For sweetness in the mochi.
Step-by-Step Instructions
Step 1: Prepare the Mochi Filling
- Mix Mochi Ingredients: In a microwave-safe bowl, combine the mochiko, water, and 2 tablespoons of sugar. Stir until smooth.
- Cook the Mochi: Microwave the mixture on high for 1 minute. Stir well, then return to the microwave and heat for an additional minute. Stir again and microwave for another 30 seconds if necessary until the mixture is thick and sticky.
- Cool and Shape: Allow the mochi to cool slightly. Once cool enough to handle, dust your hands with cornstarch, take small portions of the mochi, and shape them into small balls (about 1 inch in diameter). Place the balls on a plate or parchment paper and set them aside to cool completely.
Step 2: Make the Cookie Dough
- Preheat Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
- Mix Cookie Ingredients: In a large bowl, combine the peanut butter, brown sugar, granulated sugar, egg, vanilla extract, baking soda, and matcha powder. Mix until everything is well incorporated.
Step 3: Stuff the Cookies
- Shape Cookie Dough: Take about 1-2 tablespoons of cookie dough and flatten it in your palm. Place a mochi ball in the center and carefully wrap the cookie dough around the mochi, sealing it well.
- Place on Baking Sheet: Space the stuffed cookie dough balls about 2 inches apart on the prepared baking sheet.
Step 4: Bake the Cookies
- Bake: Bake in the preheated oven for about 10-12 minutes, or until the cookies are set and slightly golden at the edges.
Step 5: Cool and Serve
- Cool: Allow the cookies to cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely.
- Enjoy: Serve and enjoy your delicious mochi-stuffed matcha peanut butter cookies!

Tips for the Best Cookies
- Use Fresh Ingredients: Ensure that your peanut butter and other ingredients are fresh for the best flavor.
- Mochi Consistency: If your mochi dough is too sticky, add a little more mochiko. If it’s too dry, add a small amount of water.
- Storage: Store cookies in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week.
- Freezing Options: These cookies freeze well! You can freeze the uncooked stuffed dough and bake from frozen, just add a couple of extra minutes to the baking time.
