Irresistible Keto Cheesecake In a Mug

The first time I made this keto cheesecake in a mug, it was a rainy Tuesday. My toddler had just gone down for a nap, and I needed something sweet—fast, cozy, and without the sugar crash. I stirred it together with one hand, coffee in the other, and by the time the microwave beeped, it felt like a tiny victory. Soft, rich, and creamy, with the warmth of vanilla and just the right touch of tang… it’s become a go-to dessert when I need comfort without compromise.

Helpful Tips for the Best Mug Cheesecake

Microwave Timing Tips

Microwaves vary, so start with 1 minute, then check. The center should look set and pull away from the edges slightly. If it’s still jiggly, microwave for 10–15 seconds more.

Overcooking will make it rubbery, so keep a close eye.

Optional Flavors & Mix-Ins

You can add a little almond, coconut, or peppermint extract if you’re in the mood to change things up.

Sometimes I add a tiny squeeze of lemon or toss in a few dark chocolate chips for a surprise in every bite.

Want a Baked Version?

If you prefer a firmer, more classic cheesecake texture, just bake it! Preheat your oven to 350°F and bake the mixture in a ramekin for 18 to 20 minutes. Let it cool before diving in—it sets up beautifully.

Tools You’ll Need

All you need is a:

• Microwave-safe ramekin or mug
• Small whisk or fork
• Microwave or oven

Simple tools for a simple dessert.
