5-Minute Lemon Raspberry Mug Cake

This easy raspberry lemon mug cake can be made in a microwave in less than 5 minutes! It's light, fluffy and all you need are a couple of ingredients.
Prep Time: 3 minutes
Cook Time: 2 minutes
Total Time: 5 minutes
Servings: 1


  • 1/4 cup all purpose flour
  • ½ tsp baking powder
  • 2 tbsp granulated sugar
  • 1/4 cup milk
  • 2 tbsp melted butter or vegetable oil
  • ½ tsp lemon zest
  • 1 tbsp fresh raspberries

For serving (optional): 

  • whipped heavy cream


  • In a small bowl, place the flour, baking powder and sugar. 
  • Mix to combine. 
  • Add the milk, melted butter and lemon zest and whisk to combine. 
  • Fold in the fresh raspberries. 
  • Pour the batter in a large microwave safe mug. 
  • Microwave on high for 1 ½ -2 minutes or until just firm to touch and toothpick inserted into the center comes out clean.  
  • Serve with whipped heavy cream.


  • Use a different flour. I usually make most of my homemade mug cake recipes with the combo all purpose flour and baking powder. However, every now and then I’ll run into a recipe where that combination just doesn’t quite cut it and I end up with a mug cake that isn’t rising properly. Switching to a self-rising flour is a great way to easily resolve this issue.
  • Monitor the microwave time. Mug cakes are notorious for being super easy to accidentally overcook. You’re going to be far better off if you undercook your mug cakes as opposed to overcooking them. It’s easy to fire your mug cake into the microwave for a few extra seconds to fix if it’s undercooked but once you overcook your mug cake, it’s overcooked forever.
  • Enjoy with your favorite toppings. Mug cakes can be delicious when enjoyed on their own but they’re even better when served with just the right topping. For this particular lemon raspberry mug cake recipe, you can use either heavy whipped cream or your preferred mug cake topping. A few other great options include fresh berries, chocolate sauce (or even raspberry sauce), or chopped nuts (such as almonds, pecans, or walnuts).
