Easy Strawberry Mug Cake Recipe
This is a single-serving strawberry mug cake: a soft, fluffy little cake mixed right in the mug and cooked in the microwave in about a minute and a half. Fresh chopped strawberries fold through the batter so it tastes genuinely fruity, and it's ready before the oven would even preheat.
Why you'll love this
- One mug, a fork and a microwave - no oven, no mixer, and barely any washing up
- A true single serving, so you get a warm cake without half a tray left tempting you
- Real chopped strawberries fold through for fresh fruit flavor, not artificial syrup
- Start to finish in just a few minutes for an instant sweet fix
Key ingredients & swaps
- All-purpose flour — the structure of the little cake; measure it by spooning into the spoon and leveling, since packed flour is the number-one cause of a dense, rubbery mug cake.
- Sugar — sweetens and keeps the crumb tender and moist; a fine granulated or caster sugar dissolves fastest in such a small batter.
- Baking powder — the lift that keeps it light in the short microwave time; make sure it's fresh (opened within about six months) or the cake bakes up flat and tough.
- Milk plus oil or melted butter — the milk brings moisture and the fat brings richness and a soft crumb; oil keeps it tender, while melted butter adds more flavor - either works.
- Vanilla extract and a pinch of salt — small amounts that round out the flavor so the cake doesn't taste flat or purely sweet.
- Fresh strawberries — two or three berries, chopped, folded in for juicy pockets of real fruit; pat them dry and use fresh rather than frozen, which weep liquid and make the batter soggy.
How to make it (step by step)
-
1Mix the dry base
In a roomy microwave-safe mug (at least 10-12 oz), whisk together the flour, sugar, baking powder and salt with a fork until evenly combined. A wider mug keeps the batter shallow so it cooks through without toughening.
-
2Stir in the wet
Add the milk and the oil or melted butter plus the vanilla, and stir just until you have a smooth batter with no dry pockets in the bottom corners. Stop the moment it comes together - overmixing makes a mug cake dense and gummy.
-
3Fold in the strawberries
Gently fold in the chopped strawberries so they're spread through the batter, and scrape down any flour clinging to the sides. The batter should sit no more than halfway up the mug to leave room to rise.
-
4Microwave until just set
Microwave on high for about 1 minute, then check: the top should look set and dry rather than wet or glossy, and a toothpick should come out with just a few moist crumbs. If it's still wet, add 10-20 seconds at a time.

Rest, then top and eat
Let it rest about a minute so the residual heat finishes the center and it firms up slightly. Eat it warm straight from the mug, with a spoon of whipped cream or a scoop of vanilla ice cream if you like.
Pro tips
- Undercook rather than overcook - start at 60 seconds and add short bursts, because a mug cake goes from soft to rubbery in seconds and you can't undo it.
- Spoon and level the flour instead of scooping; too much flour is the main reason mug cakes turn out dense and dry.
- Use a wide mug filled only halfway so the batter cooks evenly and has room to climb.
- Pat fresh strawberries dry, or thaw and drain frozen ones thoroughly, so the extra juice doesn't leave a wet, sunken center.
Variations
- Strawberries and cream: top with whipped cream or a splash of cream for a shortcake feel.
- Chocolate-strawberry: stir a teaspoon of cocoa into the dry mix or scatter a few chocolate chips through the batter.
- Vegan: this version is already egg-free - use a plant milk and oil to keep it fully dairy-free.
Storage & freezing
Mug cakes are best eaten fresh and warm the minute they're made, as they firm up and dry out quickly; if needed, cover and keep at room temperature a few hours and warm for a few seconds before eating.

Tips & notes
- Overmixing the Batter: Overmixing can result in a dense cake. Stir the ingredients until just combined for the best texture.
Using Frozen Strawberries: Fresh strawberries work best for this recipe. Frozen strawberries can make the cake too watery.
Overcooking: Microwaves vary in power, so start with a shorter cooking time and add a few more seconds if needed. Overcooking can make the cake dry.

Frequently asked questions
Why is my mug cake rubbery or dense?
Almost always too much flour, overmixing, or overcooking. Spoon and level your flour, stir only until just combined, and start at about 60 seconds in the microwave, adding time in short bursts so the center stays tender.
Can I use frozen strawberries?
Fresh is best because frozen berries release a lot of liquid that can make the cake soggy and sink. If you only have frozen, thaw them first, drain off the juice, and pat them dry before folding them in.
What size mug should I use?
Use a microwave-safe mug of at least 10-12 oz and fill it only about halfway. A wider, roomier mug keeps the batter shallow so it cooks through evenly and has space to rise without overflowing.
Does this mug cake need an egg?
No - this is an egg-free recipe leavened with baking powder, with milk and oil or butter for moisture and richness. That also makes it quick and easy to keep vegan with plant-based swaps.
How long do I microwave a mug cake?
Generally about 1 to 1.5 minutes on high, but microwaves vary, so check at 1 minute. It's done when the top looks set and a toothpick comes out with just a few crumbs; add 10-20 second bursts if needed.
Why did my mug cake overflow?
The mug was too full or too small. Fill the mug no more than halfway, since the baking powder makes the batter rise quite a bit during cooking, then settle as it cools.
Can I use oil instead of butter?
Yes. Oil keeps the crumb especially soft and moist, while melted butter adds a little more flavor. Use whichever you have - just keep the amount the same.
