The Story & Introduction
Hi, I’m Marilyn, 38, from the beautiful island of Crete in Greece. Growing up, I learned from my grandmother that baking wasn’t just about following recipes it was about creating little moments of happiness. I remember her telling me, “Even a small dessert can make a big smile.”
That’s exactly how I feel about this Chocolate Chip Cookie in a Cup recipe. It’s the perfect dessert for when you crave something sweet right now but don’t want to turn on the oven or make a mess. Just mix, microwave, and enjoy!
The first time I made this, it was late at night, and I wanted a cookie without the cleanup. I grabbed a mug, a few simple ingredients, and within a minute, I was sitting on the couch with a warm, gooey cookie. It felt like a cozy hug in dessert form!
This Chocolate Chip Cookie in a Cup is soft, buttery, and filled with melty chocolate chips. It’s a single-serve treat made in your favorite mug no mixing bowls, no baking trays, and no waiting.

Step 5: Microwave & Enjoy
Microwave for 45–60 seconds (depending on your microwave power). The cookie should look set on top but still soft inside it’ll continue cooking as it rests.
Let it cool for 2 minutes, then grab a spoon and enjoy your warm, gooey Chocolate Chip Cookie in a Cup straight from the mug!
Serving & Tips
Serve your cookie warm for the best texture. You can top it with a scoop of vanilla ice cream, whipped cream, or a drizzle of chocolate syrup.
Pro Tips:
- Use a microwave-safe mug that holds at least 8 oz.
