Strawberry
Eggless Strawberry Mug Cake
Pink, fluffy, and entirely egg-free. Tastes like a strawberry milk shake set with flour.
Steps
-
Fork-whisk flour, sugar, baking powder, and salt in the mug. Strawberries are acidic, so the baking powder reacts quickly once liquid joins — work without long pauses from here.
-
Pour in the strawberry puree, milk, oil, and vanilla. Stir until the batter is uniformly pink with no flour pockets at the bottom.
-
Drop the strawberry jam on top of the batter and drag a chopstick through in two figure-eights. Stop — over-swirling sinks the jam to the bottom.
-
Microwave on high for 70-80 seconds. The top should spring back lightly when tapped.
-
Cool for 60 seconds. The jam pockets are nuclear straight out of the microwave.
Tips from the test kitchen
Frozen strawberries (thawed) puree more smoothly than fresh ones and the color is brighter. Pat off excess liquid before blending or the cake turns gummy.
Success guide
Make it work the first time
Expected texture
Expect a fluffy cake with moist fruit pockets. Strawberry puree and jam add water, so the cake should be set on top but not cooked until dry.
Success tips
- Use a microwave-safe mug with visible headroom. If the batter fills more than about half the mug, move it to a larger mug before cooking.
- Start with the lower end of the microwave time in the steps. Add time in short bursts only if the center still looks wet.
- Let the cake rest before eating. The crumb keeps setting after the microwave stops, and the mug will be very hot.
- This recipe avoids a whole egg, which helps prevent the bouncy texture people often dislike in small mug cakes.
Substitutions
- Milk
- Whole milk gives the softest crumb. Unsweetened oat or almond milk can work, but the cake may taste a little lighter.
- Fat
- Neutral oil keeps mug cakes moist. Melted butter works in some chocolate or vanilla cakes, but it can make the crumb firmer as it cools.
- Flour
- Do not assume a direct gluten-free flour swap unless the blend is labeled cup-for-cup; the texture may turn gummy.
- Mix-ins
- Keep heavy mix-ins near the center of the batter. If they touch the mug wall, they can overheat before the cake finishes.
Troubleshooting
- Rubbery texture
- Usually caused by overmixing, overcooking, or too much egg for one mug. Mix only until no dry flour remains and stop at the first set-top cue.
- Dry crumb
- The cake likely cooked too long. Next time start at the low end of the time range and let rest instead of microwaving until fully dry.
- Overflow
- The mug was too small or too full. Use more headroom and set the mug on a paper towel if your microwave runs hot.
- Wet center
- Microwave in one short burst, then rest again. A slightly glossy center is fine; a puddle of batter needs more time.
Variations
- Add a few mini white chocolate chips for a strawberries-and-cream feel.
- Spoon a little extra jam on top after the cake rests.
- Add a fresh spoonful of jam after cooking if you want brighter fruit flavor.
