What is mochi?
Mochi are Japanese rice cakes made of glutinous rice (mochigome). Traditionally, the rice is cooked, then pounded, then formed into round balls to be eaten. In this recipe, we add mochi to the center of miso peanut butter cookies for a uniquely flavorful combination.
What is miso?
Miso a traditional Japanese seasoning. It is made of fermented soybeans, salt, and kōji (a fungus). It has a tangy flavor that adds an exciting dimension to the cookies.
Ingredients
- Mochiko glutinous rice flour - Mochiko sweet rice flour provides structure to the cookies. It is also naturally gluten free.
- Natural Peanut butter - Creamy peanut butter is best for a smooth cookie texture.
- All-purpose flour - Flour is the foundation for these mochi cookies.
- Baking soda - Baking soda helps the cookie dough spread.
- Baking powder - Baking powder helps make the miso cookie dough soft and tender.
- Butter - Room temperature butter is best for the cookie dough texture and adds a buttery flavor. We like European butter because it has a higher fat content resulting in a crisper, more buttery cookie.
- Sugar - Sugar adds sweetness to the cookies and helps the cookies spread as the sugar melts.
- Brown sugar - Brown sugar adds moisture and makes the cookies tender.
- Vanilla extract - Vanilla extract adds complexity and sweetness to the cookie dough. For a stronger vanilla flavor, use vanilla bean paste.
- Egg - Egg binds the ingredients together. Use a room temperature egg so it spreads evenly in the cookie dough.
- White miso paste - Miso paste gives the cookie a warm savory and lightly sweet flavor. We like Hikari miso paste because it is high-quality yet affordable.

Assemble Mochi Stuffed Peanut Butter Cookies
- Prepare cookie dough and mochi - Use a small ice cream scooper, cookie dough scooper, or tablespoon to scoop the dough and form cookie dough into 18 or so balls. Divide the mochi into as many pieces as there are cookie dough balls so the quantities match. Dust your hands with corn or potato starch and roll the mochi into balls. (Photo 5, 6, and 7)
- Assemble cookies - Use your hands to flatten each cookie dough ball and place a mochi ball in the center of each cookie dough disk. Hold the cookie dough disc in your hand and fold the edges of the circle into the middle to cover the mochi ball.(Photo 8)
- Roll cookies - Pinch the edges in the middle to seal the cookie dough and roll each ball once in your hands to smooth the bottom. If desired, place coarse sugar in a shallow bowl and gently roll each ball in the sugar bowl until covered. Place the dough balls onto the prepared cookie sheets. Leave 1½-2 inches between each cookie to allow the dough to spread. (Photo 9, 10, and 11)
- Bake the cookies - Place the cookies on the middle rack in the oven and bake for 10-12 minutes. The cookies will look soft in the middle and the edges will turn slightly golden. Let the cookies rest for 5 minutes on the cookie sheet then transfer to a wire rack to cool.
Pro tip: Use room temperature butter and egg so the dough creams successfully.
What to Serve with Mochi Miso Cookies
Mochi cookies are a delicious dessert or snack. We usually enjoy them with as a dessert with a glass of oat milk for dipping, hot chocolate, or caramel iced coffee. They are also delicious as a snack with a matcha lemonade.
Recipe FAQs
One of the most common reasons cookies are too dry is too much flour. People often measure flour incorrectly by scooping directly from the canister and overpacking the flour. Properly measure flour by fluffing the flour in its canister, spooning the flour into a measure cup, and scraping a knife across the top of the measuring cup to level the flour.
Making fork marks helps the cookies bake evenly. Since peanut butter cookie dough is dense, pressing down on the dough with a fork can help ensure they cook evenly. Our recipe works without the fork prints, but you can add them for texture if you would like.
Mochi tastes like sweet rice but with a stretchy and chewy texture.
While mochi isn't super healthy for you, it is better for you than many other sweet snacks and desserts. It is low in saturated fat and cholesterol and is a good source of good source of Vitamins A, C, E, and K; Potassium; Protein; Magnesium, Copper, and Manganese.
No, mochi is traditionally cooked on the stovetop or microwaved. Check out our kinako mochi if you want to make mochi through this method. In this recipe, we bake the mochi and is still delicious.
