Ingredients

Instructions

  1. Step 1: In a large microwave-safe mug, whisk together 4 tbsp all-purpose flour, 3 tbsp granulated sugar, 1/4 tsp baking powder, 1 tsp poppy seeds, and a small pinch of salt until combined.
  2. Step 2: Add 3 tbsp milk, 2 tbsp vegetable oil, 1 tsp lemon zest, 1 tbsp lemon juice, and 1/4 tsp vanilla extract to the dry ingredients, whisking until smooth and free of lumps.
  3. Step 3: Microwave the mug on high for 90 seconds, checking at 60 seconds to ensure it’s rising evenly — the cake should be set but moist.
  4. Step 4: Let the mug cake cool for 2 minutes before eating directly from the mug or gently removing it onto a plate.

Frequently asked questions

Total time is about 7 minutes (5 min prep + 2 min cook). Most home bakers find this fits a weekend afternoon; chill or store as the recipe directs before serving.

How do I store leftover Microwave Mug Lemon Poppy Seed Cake?

Cool fully before storing. Most baked desserts keep at room temperature in an airtight container for 2–3 days, or in the fridge for up to 5 days. Cream- or custard-based desserts must go in the fridge within 2 hours; reheat gently or serve cold per the recipe.

Can I substitute ingredients in Microwave Mug Lemon Poppy Seed Cake?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Microwave Mug Lemon Poppy Seed Cake for a different number of people?

The recipe is written for 1 servings. Multiply each ingredient by (your serving target / 1). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
