Ingredients for the Best Vegan Mug Cake

Here’s what you’ll need:

• 1 ripe banana (medium-sized, the spottier the better)

• 3 tablespoons almond flour (or oat flour for a heartier texture)

• 1 tablespoon unsweetened cocoa powder
  
  

That’s it. No baking powder, no added sugar (the banana does the sweet-talking), and no fuss.

Optional add-ins if you’re feeling indulgent:

• A pinch of cinnamon or vanilla extract

• A few vegan chocolate chips

• Chopped nuts or shredded coconut

How to Make This Quick Vegan Mug Cake (5 Steps)

1. Mash the banana thoroughly in your CURVD mug.

2. Stir in the almond flour and cocoa powder until smooth. If adding extras, toss them in now.

3. Microwave for 1 to 1.5 minutes on high, depending on your microwave's power.

4. Let it cool for a minute (we know it’s hard to wait).

5. Top with nut butter, coconut yogurt, or eat it as is—straight out of the mug.

Personal Tips from a Vegan Dessert Lover

• Ripe bananas are key. The riper they are, the sweeter and softer your cake will be.

• Almond flour gives the fluffiest result, but oat flour adds a wholesome touch.

• Microwave time matters. Overcooking will dry it out. Start with 1 minute and test.

• Use a CURVD ceramic mug. Its shape retains heat evenly, which is crucial for texture.

• Add a dash of salt if you're using sweet toppings; it balances the flavors beautifully.

• Try it with a homemade iced matcha latte, you won’t regret it! Get our special recipe here.
