What you will need
This recipe uses 6 simple ingredients that you can find at any grocery store:
- 4 tbsp all-purpose flour
- 3 tbsp granulated sugar
- 1 tsp poppy seeds
- 3 tbsp whole milk
- 2 tbsp melted butter
- 1 tsp fresh lemon zest
Step by step instructions
Step 1: Combine Dry Ingredients
Stir together the flour, sugar, and poppy seeds in a large microwave-safe mug until evenly distributed.
Step 2: Add Wet Ingredients
Pour in the milk, melted butter, and lemon zest, then stir until the batter is smooth and the zest is evenly mixed throughout.
Step 3: Microwave the Cake
Microwave on high for 70 to 85 seconds until the surface is set and the cake has risen slightly in the mug.
Step 4: Glaze and Serve
Whisk together a teaspoon of powdered sugar with a few drops of fresh lemon juice and drizzle over the warm cake before serving immediately.
Easy substitutions
Missing an ingredient? Here are some swaps that work perfectly:
- fresh lemon zest → half a teaspoon of lemon extract for a more concentrated citrus flavor
- poppy seeds → chia seeds for a similar texture and visual appearance
Common mistakes to avoid
Watch out for these pitfalls that can affect your results:
- Using bottled lemon juice instead of fresh zest produces a flat and artificial lemon flavor rather than bright and aromatic citrus
- Overcooking the cake makes it dry and rubbery which removes the delicate tender crumb that makes this mug cake special
