🍫 Classic Chocolate 3 Ingredient Mug Cake Recipe – Pure Comfort in a Cup

3 ingredient mug cake

If I had to pick one dessert to keep me company on cozy evenings, this would be it. The classic chocolate 3 ingredient mug cake was the very first one I ever made—and honestly, it was love at first bite. 💘

It’s rich, gooey, and full of deep cocoa flavor, yet so light and pillowy you’d never believe it’s made with just three ingredients. This recipe has become my go-to on rainy days, Netflix marathons, and even stressful work nights when all I want is a warm, chocolatey hug in dessert form. 🍫🫶

The best part? No fancy tools, no long ingredient list, no waiting for preheating. Just one mug, a few pantry staples, and 60 seconds of microwave magic. ✨


🧁 What You’ll Need:

  • 1 ripe banana (the riper, the better – it makes the cake extra sweet and moist) 🍌
  • 2 tablespoons unsweetened cocoa powder
  • 1 tablespoon nut butter (peanut butter, almond butter, or whatever you love most)

👩‍🍳 How to Make It:

  1. Mash the banana directly in your mug using a fork until it’s completely smooth.
  2. Stir in the cocoa powder and nut butter. Mix well until the batter is thick and evenly blended.
  3. Microwave on high for about 60 seconds. The cake should puff up and look set in the center.
  4. Let it sit for 30 seconds (trust me, it’s hot!), then dive in with a spoon and a big smile. 😍

🍫 Optional but Highly Recommended:

  • Sprinkle a few dark chocolate chips on top before microwaving for a gooey, molten center.
  • Add a dash of cinnamon or vanilla extract for extra flavor.
  • Want to feel fancy? Top it with whipped cream, a scoop of vanilla ice cream, or a drizzle of nut butter once it’s done.

This 3 ingredient mug cake has saved me from so many dessert emergencies. It’s rich enough to feel indulgent, but wholesome enough (hello, banana! 🍌) that I don’t feel guilty one bit. Whether it’s a self-care Sunday or a mid-week reward, this chocolatey dream is always a good idea. 💭💕
