• ¼ cup (35g) all-purpose flour
• 2 tablespoons (25g) granulated sugar
• ¼ teaspoon baking powder
• Dash of salt
• 2 tablespoons (28g) unsalted butter, melted
• 3 tablespoons (45ml) milk (any kind – whole milk is richest)
• ½ teaspoon vanilla extract (use pure for best flavor)

Prep Time: 2 minutes Cook Time: 70–90 seconds Total Time: Under 5 minutes Calories: ~320 (without toppings)

Instructions

1. Choose your mug — Use a large microwave-safe mug (at least 12–16 oz) to prevent overflow.
2. Mix dry ingredients — Add flour, sugar, baking powder, and salt directly into the mug. Stir well with a fork.
3. Add wet ingredients — Pour in melted butter, milk, and vanilla extract. Stir until the batter is completely smooth and no dry pockets remain. Scrape the bottom of the mug.
4. Add mix-ins — Gently stir in sprinkles or chocolate chips.
5. Microwave — Cook on high for 70–90 seconds. The cake is done when it looks just set but still slightly shiny on top. Do not overcook — it firms up as it cools.
6. Cool slightly — Let it rest for 1 minute. Top with whipped cream, ice cream, or extra sprinkles and enjoy straight from the mug!

Tip: Microwave times vary. Start with 70 seconds and add 10-second increments if needed.

Pro Tips for the Best Vanilla Mug Cake

• Don’t overmix — Stir just until combined for a tender crumb.
• Mug size matters — Too small and it will overflow. Use a tall, wide mug.
• Milk & butter — Room temperature ingredients blend better.
• Avoid rubbery texture — Stop microwaving as soon as the top looks set.
• Egg version (richer) — Add 1 egg yolk with the wet ingredients for a more cake-like result.
• Gluten-free — Swap all-purpose flour with a 1:1 gluten-free blend.

Delicious Variations

• Funfetti Vanilla Mug Cake — Double the sprinkles!
• Chocolate Chip — Add 2 tbsp mini chocolate chips.
• Lemon Vanilla — Add ½ tsp lemon zest + 1 tsp lemon juice.
• Birthday Cake — Top with vanilla frosting and extra sprinkles.
• Protein-Packed — Stir in 1 tbsp vanilla protein powder (adjust milk slightly).

Make-Ahead & Storage

• Best fresh — Mug cakes are designed to be eaten immediately.
• Refrigerator — Store leftovers (rare!) up to 1 day. Reheat in microwave 15–20 seconds.
• Meal Prep Hack — Mix dry ingredients in advance in several mugs for ultra-fast desserts.
