Key Lime Mug Cheesecake
A creamy, tangy Key Lime Mug Cheesecake made in the microwave with a buttery graham cracker crust. Single-serve, quick, and irresistibly zesty—perfect for when dessert cravings strike.
- Total Time: PT35M
- Yield: 1 serving
Ingredients
2 tablespoons graham cracker crumbs
1 tablespoon unsalted butter, melted
3 ounces cream cheese, softened
2 tablespoons granulated sugar (or sweetener of choice)
1 tablespoon sour cream (or Greek yogurt)
1 tablespoon fresh key lime juice
1/2 teaspoon finely grated key lime zest, plus more for topping
1/2 teaspoon vanilla extract
Pinch of fine sea salt
Optional: whipped cream, extra lime zest, crushed graham crackers for garnish
Instructions
1. Make the crust: In a 12-ounce microwave-safe mug, mix the graham cracker crumbs and melted butter until the texture resembles wet sand. Press firmly into an even layer.
2. Make the filling: In a small bowl, whisk or beat the softened cream cheese, sugar, sour cream, key lime juice, lime zest, vanilla, and a pinch of salt until completely smooth and creamy. Spoon over the crust. Tap the mug gently to release air bubbles.
3. Microwave: Cook on 50% power in 20–25 second bursts for 60–75 seconds total, letting it rest 10 seconds between bursts. Stop when edges are set and the center is slightly jiggly.
4. Cool and chill: Let the mug cheesecake cool on the counter for 10 minutes, then chill 20–30 minutes (or freeze for 10 minutes) until set.
5. Finish and serve: Top with whipped cream, extra lime zest, and a pinch of crushed graham cracker. Enjoy straight from the mug.
Notes
Soften cream cheese fully for a silky texture. Tap the mug before microwaving to remove air bubbles. Always cook on 50% power to avoid curdling.

Easy Key Lime Mug Cheesecake (Microwave Method)
Simple steps for consistent results
For a smooth Key Lime Mug Cheesecake, start with softened cream cheese. Whisk in sugar, sour cream, key lime juice, vanilla, and lime zest until satiny. Press a quick graham-butter crust in a microwave-safe mug. Spoon the filling on top, then microwave the cheesecake on 50% power, in short bursts, to avoid overheating. The center should look slightly jiggly. That’s how Key Lime Mug Cheesecake achieves the classic cheesecake set after chilling.
Microwave strengths vary, so keep an eye on the edges. Let the cheesecake rest between bursts to distribute heat evenly. Tap the mug on the counter before cooking to pop air bubbles for a denser, creamier finish. Chill to set the citrus cheesecake and prepare your lime zest garnish.
Practical tips and pro moves
- Use a 12-ounce (or larger) microwave-safe mug to prevent spillover.
- Cook at 50% power for creamy Key Lime Mug Cheesecake. High power can curdle dairy.
- Chill at least 20 minutes for clean spoonfuls. Ten minutes in the freezer works in a pinch.
- Try a shortbread or digestive biscuit crust for a buttery twist on mug cheesecake.
- For a richer Key Lime Mug Cheesecake, add an extra teaspoon of sour cream for lush tang.

Healthy Key Lime Mug Cheesecake Variations
Lighter swaps for your mug cheesecake
There are easy ways to make Key Lime Mug Cheesecake lighter while keeping that creamy, tangy bite. Swap sour cream for plain Greek yogurt, or use Neufchâtel (1/3 less fat) cream cheese. Choose a stevia, monk fruit, or allulose blend instead of sugar. For the crust, try almond flour mixed with a touch of coconut oil, or crumble a gluten-free cookie. Each choice keeps your Key Lime Mug Cheesecake bright and refreshing, with the same citrus cheesecake soul.
- Protein boost: blend in 1 to 2 teaspoons of unflavored whey or collagen.
- Lower carbs: use crushed pecans or almond flour instead of grahams.
- Dairy-light: replace half the cream cheese with thick Greek yogurt for tang.

Make-Ahead Key Lime Mug Cheesecake: Storage & Fixes
How to store your single-serve cheesecake
Key Lime Mug Cheesecake keeps well covered in the refrigerator for up to 2 days. To preserve texture, chill it uncovered for 20 minutes first, then cover. For longer storage, remove from the mug and wrap tightly before freezing up to 1 month. Thaw in the refrigerator and finish with fresh lime zest and whipped cream. This way your Key Lime Mug Cheesecake tastes as bright and creamy as day one.
Troubleshooting and quick FAQs
