I read a recipe a while back about a chocolate cake that was cooked in 3 minutes in the microwave. I didn’t really believe it, but I tried it out and then proceeded to alter it to suit my own tastes because I thought it was too heavy and the texture was a bit wonky – if decent for an instant chocolate fix at 12:00 in the morning. Still, the unpleasant texture just became more pronounced as I experimented with vanilla variations. At last, here is my 5-minute lemon-poppy seed cake that rises beautifully and is light and airy – unlike the chocolate cake.

Recipe Ingredients

  • ¼ cup all-purpose flour
  • ¼ cup white sugar
  • 3 tablespoons buttermilk
  • 3 tablespoons vegetable oil
  • ½ teaspoon baking soda
  • 1 tablespoon poppy seeds
  • 1 teaspoon lemon extract
  • 1 egg

Cooking Directions

  1. 1 Whisk flour, sugar, buttermilk, vegetable oil, baking soda, poppy seeds, and lemon extract together in a bowl until smooth. Beat in the egg. Pour batter into a large microwave-safe glass or ceramic mug or cereal bowl.
  2. 2 Heat in the microwave on high until a toothpick inserted into the center comes out clean, about 3 minutes.

Chef's Notes

Want a totally vanilla cake? Strike out the poppy seeds and lemon extract and use 1 teaspoon vanilla extract instead; For years my mother made buttermilk for homemade Southern-style biscuits by curdling milk with some vinegar. This seems like a bit of work for this recipe; if I did not have store buttermilk on hand I think I would try plain nonfat yogurt in place of buttermilk.


  1. I was expecting it to be a Little more lemony but the texture was pretty good for a microwave cup recipe.
  2. I tried this and it would just burn and change colors in the middle. I tried changing the cook time because of the high wattage my microwave has. It still burned on me. It was a good experiment but I won't be doing this again.
  3. The taste was okay but I'm reviewing to say DO NOT use yogurt as a sub for buttermilk as suggested in the Cook's Notes. I did & it was horrible!!! It came out rubbery & chewy ick! But I will try it again I just didn't want anyone else ending up with the mess I - Read more ...
  4. I've had the microwave chocolate cake many times and I've never once gotten it to turn out. I tried the vanilla option for this and for a microwave cake it was fantastic. I'm out of eggs so I tried it without an egg and a little extra buttermilk and hoped for the best. I microwaved - Read more ...
  5. I had high hopes for this recipe and really really wanted to like it but for the life of me I can't get this to turn out. I've tried several times each with an oversized 2c. ceramic coffee mug. It always looks great from the outside but it keeps burning on the inside. I've reduced - Read more ...
  6. This was a fun experiment but not one I'll repeat. While not exactly inedible there was just something offputting about the texture and taste. I added a lemon glaze to top it off which definitely helped.
  7. The texture is a bit wierd but it might be because I used Splenda Egg Beaters and fat free buttermilk. The taste is right on for a lemon cake. I thought I had poppyseeds but alas I didn't and already had the rest made. So cooked in my microwave for exactly 2 1/2 minutes worked - Read more ...
  8. I used a large cereal bowl and it turned out quite well at 3 min. The middle looked different/soft at first but cooled to the same shortly. I reduced the sugar to a bit over half but then ended up sprinkling it on top. Not as lemony since I used lemon juice. The milk/vinegar substitute - Read more ...
  9. If you're at high altitude like me better split it between two mugs... mine spilled over during the cook time. I didn't have lemon extract so I used juice and grated peel... probably would have been more flavorful with the extract... not bad overall especially if you sprinkle it with more sugar.
