Peanut Butter Chocolate Chip Mug Cake 🥄🍫

Craving a warm, gooey dessert but don’t want to bake a whole batch? This Peanut Butter Chocolate Chip Mug Cake is your instant dessert fix – made in minutes with pantry staples, right in the microwave!

Why You’ll Love It 💚

  • Single-serving: Perfect for when you want dessert—now.
  • No oven needed: Cooks in just 1 minute in the microwave!
  • Super gooey: Peanut butter and melted chocolate chips make the center irresistible.

🛒 Ingredients

  • 2 tablespoons all-purpose flour
  • 1 tablespoon brown sugar
  • ¼ teaspoon baking powder
  • Pinch of salt
  • 2 tablespoons milk (any kind)
  • 1 tablespoon peanut butter (creamy or chunky)
  • ½ tablespoon neutral oil (or melted butter)
  • ¼ teaspoon vanilla extract
  • 1 tablespoon chocolate chips

👩‍🍳 Instructions

  1. Mix dry ingredients: In a microwave-safe mug, whisk together flour, brown sugar, baking powder, and salt.
  2. Add wet ingredients: Stir in milk, peanut butter, oil, and vanilla extract until smooth and fully combined.
  3. Fold in chocolate chips gently, leaving a few on top for a gooey finish.
  4. Microwave on high for 45–60 seconds. The cake should rise and look just set on top, but still soft inside.
  5. Cool slightly before digging in—best enjoyed warm and melty! 🥄

💡 Pro Tips & Variations

  • Use a wide mug: Helps the cake cook evenly and prevents overflow.
  • Don’t overcook: Check at 45 seconds; the center should still be slightly gooey!
  • Richer version: Use whole milk and a dollop of butter for an ultra-decadent treat.
  • Make it nut-free: Swap peanut butter for sunflower seed butter or tahini.
  • Vegan option: Use plant-based milk and vegan chocolate chips—easy!

🍦 Serving Suggestions

  • 🍨 With a scoop of vanilla ice cream for a lava-cake-style dessert.
  • 🍓 Topped with fresh berries for a fruity twist.
  • 🥄 Extra drizzle of warm peanut butter or chocolate sauce on top.

🥡 Make-Ahead & Storage

  • 🕒 Prep ahead: Mix dry ingredients in a mug and store covered. Add wet ingredients just before microwaving.
  • 🚫 Don’t refrigerate: This mug cake is best eaten fresh. Leftovers dry out quickly.

❓ FAQ

  • Can I double the recipe?
    Yes, but use a larger bowl and microwave in 30-second intervals to avoid overflow.
  • Why is my mug cake rubbery?
    It’s likely overcooked. Try reducing microwave time by 10–15 seconds.
  • Can I use almond flour?
    Yes, but the texture will be denser. Use 2.5 tbsp almond flour for best results.
