"This was really yummy and one of the quicker mug recipes I've ever made!" - Jess
I'm all for using chocolate chips in baking, whether it's a batch of chocolate chip cookies, double chocolate muffins, or homemade granola bars. But some days I'm after a little single-serve indulgence, just for me, and that's where this mug cookie comes in.

Why You're Going To Love This Recipe
- Quick and easy - just mix in a mug and microwave, ready in about 2 minutes total.
- Just for one - perfect for a little late-night indulgence without making a whole batch.

Mug Cookie Ingredients
Simple ingredients you likely already have on hand.
- Caster sugar - also called superfine sugar, dissolves easily when mixed and heated.
- Brown sugar - light brown sugar is used here so it doesn't distract from the chocolate chips.
- Chocolate chips - milk chocolate is used here, but white or dark chocolate chips work too. A good quality brand makes a noticeable difference.
Variations
- Chocolate swap - try dark or white chocolate chips, or even peanut butter chips, instead of milk chocolate.
- Double it - split the mixture between two mugs to share (or not!).
- Extra gooey - press a few extra chocolate chips into the top just before microwaving.
- Nutty - stir through a teaspoon of chopped pecans or walnuts.
How To Make Chocolate Chip Cookie In A Mug
You want this to look puffy on top once cooked, but warm and slightly gooey inside.
Note: Scroll to the recipe card at the bottom for the ingredient quantities and full detailed method.
- Step 1: Melt the butter, add the sugars. Melt the butter in a microwavable mug for 30 seconds, then stir through the caster sugar, brown sugar, vanilla and a pinch of salt.
- Step 2: Add the egg yolk. Mix the egg yolk through until well combined.
- Step 3: Add the flour and chocolate chips. Stir through the flour until no lumps remain, then stir through the chocolate chips.
- Step 4: Microwave and serve. Cook for 40 seconds or until just set on top (don't overcook, you want it fudgy). Enjoy immediately with a scoop of ice cream.
Recipe Tips
- Top tip: all microwaves are different; start with 40 seconds and add 5-second bursts if it's still gooey on top.
- Don't overcook - you want this cookie to still be a little gooey inside.
- Use a large mug or split into two, so it doesn't overflow while cooking.
- Serve while warm with ice cream or cream for the perfect easy dessert.
Chocolate Chip Cookie In A Mug FAQs
Yes. Milk chocolate is used here, but dark chocolate, white chocolate or even peanut butter chips all work well.
This recipe only uses the egg yolk. Store the egg white in a small container in the fridge for up to 2 days, or freeze in an ice cube tray for up to 3 months. Use it in an omelette, or in baking such as meringues, a pavlova or coconut macaroons.
Yes, simply double the ingredients and split between two mugs, cooking them individually so each one cooks evenly.
This usually happens when the mug is too small for the mixture. Use a large mug (at least 350ml) or split the mixture between two smaller mugs.
