Chocolate Chip Mochi Cookies

Soft chocolate chip cookies filled with sweet and stretchy mochi for the ultimate play on textures!

Mochi-filled desserts have been all the rage over the past couple of years and for good reason! The deliciously chewy and stretchy nature of mochi makes it perfect as a surprise filling in any baked treat, whether that be a cookie, brownie, or cake.

What is mochi?

Mochi is a chewy treat made from glutinous rice flour. While the term mochi has been popularised all over the world, mochi is the Japanese term for the glutinous rice cake that is commonly eaten all over Eastern and South-Eastern Asia, whether that be China, Korea, Philipines, Indonesia, Vietnam, etc.

Each country has their own unique preparation method and flavours to create this delicious treat, whether that be filled with sweet pastes like red bean, dusted with savoury powders, or eaten plain.

The most traditional method of making mochi is pounding steamed sweet glutinous rice flour into a paste with water. The pounding action increases the smoothness and elasticity of the mochi for a chewy treat!

How to make perfect mochi cookies

There are two components to this cookie, the mochi and the cookie dough. Both are super simple to make, but there are a couple of tips that will help ensure success when making these!

Mochi

Microwave at 1 minute bursts

There are a couple of ways to make mochi, but microwaving is the most time-efficient and easy way.

When microwaving mochi it is important to keep an eye on it and give the batter a mix in between the cooking process. This allows the mochi to cook evenly while preventing it from burning. After the initial 1 minute cook time give the batter a mix, and then cook it on 1 minute bursts until fully cooked and no longer milky.

Overcooking your batter will lead to a firmer, tougher mochi so keep that in mind!

Knead in the oil

Mochi is traditionally pounded to increase the elasticity and texture and we can recreate this at home! Rather than pounding the cooked mochi with a mallet, it is a lot easier to knead the dough.

Once the mochi has cooked pour over the vegetable oil and give it a quick mix. At this stage the vegetable oil will not be fully incorporated, however, this will help prevent the mochi from drying out as it cools.

Once the mochi dough has cooled enough to be handled, used food-safe gloves or oiled hands to knead the dough. This action will incorporate the oil, while giving the dough a softer, chewy texture. Then portion into balls to be stuffed into the cookie batter.

Cookie

Chill the dough

Chilling the dough is one of the most important tips when making any kind of cookie. Chilling the dough helps the butter to firm up, and prevents the cookie from spreading excessively while baking. In this case, it is even more important because unchilled dough will melt and slide off your balls of mochi while the cookies are baking.

You can make the cookie dough first and allow it to chill as you make your mochi. Once your mochi has cooled and been portioned the dough should be at the perfect temperature to be formed and baked.

Frequently Asked Questions

Why did my cookies spread?

The most common reason as to why your cookies spread is because the dough wasn’t chilled enough. Chilling the dough allows the butter to firm up and prevents it from melting before all the other ingredients have had time to cook during the baking process.

If you live in a warm country the process of forming the cookie dough into balls can also make your dough too warm. In this case, I would chill the assembled cookies filled with mochi for 30 minutes in the fridge before baking.

Why is my mochi tough?

Mochi can turn out tough if it has been overcooked. Everyone’s microwave is different and some will be more powerful than others, therefore it is important to keep an eye on your mochi while it is baking to prevent it from overcooking.

Overcooking the mochi draws out the moisture in the dough, resulting in a loss of elasticity and softness.

How long do these last?

These are best consumed on the day they’re made as mochi tends to firm up over time. However, they will last up to 2 days when stored in an airtight container.

Other flavour combinations

There are so many possibilities with these cookies, whether it be switching up the flavours or the toppings.

To make matcha cookies simply replace 1 tbsp of flour with 1 tbsp of matcha powder.

To make chocolate cookies replace 2 tbsp of flour with 2 tbsp cocoa powder.

Or change up the toppings and use ingredients like white chocolate, dried fruits, cookie crumbs and so much more!

    1. Hi Sheree, I would let the dough sit out at room temperature a little bit so that it softens up, that way it’ll be easier to fold in the mochi ????

  1. Hi! Am I able to chilled the dough with the mochi filling inside already over night? Or will the mochi texture be different?
