How to Make Almond Butter Mug Cake

Ready to whip up an almond butter mug cake of your very own? Follow these simple steps:

Prep Your Mug

  • Choose a microwave-safe mug that holds at least 12 ounces. This allows room for the cake to rise as it bakes.
  • Do not grease or line the mug. The cake will pull away from the sides when done.

Mix the Batter

  • Whisk together all ingredients right in the mug until smooth and uniform.
  • Be sure the egg and nut butter are fully incorporated so the cake bakes properly.


  • Cook on high for 30 seconds, then check the consistency.
  • Microwave for 10 more seconds if the batter is still very liquid on top. It should be set but still soft.
  • Do not overcook - Mug cakes taste best moist!

Finish and Enjoy

  • Allow to cool slightly before eating so chocolate chips can melt.
  • Top with whipped cream or nut butter if desired.
  • For the best texture, enjoy the mug cake warm straight from the microwave.

That's all there is to it! In just a few minutes you can be enjoying a warm, chocolatey cake layered with melted chocolate chips and creamy nut butter.

Tips for Almond Butter Mug Cake Success

Like any mug cake, there are some tips and tricks to ensure your almond butter cake turns out right:

  • Mix the batter very smoothly so the egg is fully incorporated. Lumps lead to uneven cooking.
  • Use fresh baking powder so the cake rises properly. Check the expiration date.
  • Don't overfill your mug or the cake can boil over as it cooks.
  • Microwave times vary - Cook in short increments to prevent drying out.
  • Enjoy the cake warm and fresh for the best texture before it dries out.
  • Make one mug cake at a time. Do not try to cook multiples together.

Follow these tips and you'll be a mug cake pro in no time!

Simple Variations for Almond Butter Mug Cake

One of the best things about mug cakes is how easy they are to adapt. Try these tasty almond butter mug cake variations:

  • Substitute peanut butter or another nut butter you enjoy.
  • Use chocolate almond butter for extra chocolate intensity.
  • Add cinnamon and vanilla for a snickerdoodle vibe.
  • Mix in chocolate chips or chunks for pockets of chocolate in each bite.
  • Top with sliced strawberries or bananas for fresh fruit flavor.
  • Swirl on peanut butter frosting or Nutella for more decadence.
  • Substitute cocoa powder for a chocolate almond butter mug cake.

What can I use instead of almond butter?

Any nut butter like peanut, cashew, or sunflower seed butter works well. You can also use almond flour.

Can I use quick oats instead of flour?

Yes, quick oats can substitute for flour in a 1:1 ratio. They add great texture.

What sweetener is best for keto diets?

For low-carb diets, use erythritol or stevia instead of sugar. Granulated varieties work best.

How do I make a vegan mug cake?

Swap the egg for a "flax egg" - 1 tablespoon flax meal whisked with 3 tablespoons water.

Why is my mug cake runny inside?

Be sure to cook it fully - this happens if it's undercooked. Check at 30 seconds then 10-second intervals.

Can I use a metal mug or glass dish instead?

Yes, any microwave-safe vessel will work. You may need to adjust cook times.
