As an environmental scientist, I’m always looking for ways to reduce food waste. And single-serving desserts are a great place to start!

Green tip: Did you know that of the billions of pounds of food wasted annually, it is estimated that 50% of it happens in our homes? It’s always best to avoid food waste as much as you can!

And when single-serving means slapping some ingredients together and chucking them in the microwave, I’m even more excited. This is the quickest, easiest, and most delicious microwave mug recipe you’ll ever find!

Vegan Mug Brownies Tips and Tricks



What You’ll Need

You’ll need an 8-ounce microwave-safe mug, and a fork to stir.

Outside of your mug, here’s everything you’ll need:

sugar, vanilla almond milk, oil, cocoa powder, chocolate chips, all-purpose flour

Add Your Dry Ingredients First

The key to getting a delicious vegan mug dessert is making sure there are no lumps of flour or cocoa powder.

Add your dry ingredients to the mug first, and use a fork to mix together. Ensure that there are no lumps in the dry mixture before adding your wet ingredients.

Wet Ingredients Next

Next, you’ll add both the milk and the oil. I like to use Vanilla Almond milk because it means I don’t need to add any vanilla extract.

If you don’t have any vanilla almond milk, no worries! Use any milk you have in the fridge. Option to add just a splash of vanilla extract if you’d like, but it’s not necessary.

This mug brownie is fudgy and delicious with or without it.

Once you add your wet ingredients, stir again with the fork. Make sure to run the fork around the inside edge of the mug.

This will help make sure you get any dry ingredients clinging to the edge of the mug so you don’t have any powder left in your batter.

Add Chocolate Chips Last

Once you’ve thoroughly mixed your dry and wet ingredients, all that’s left is adding your chocolate chips.

Add them last and just leave them on top—no need to stir them into your batter.

This will give you a melty chocolate top, adding to that perfect fudgy consistency.

Consider a Pinch of Sea Salt

This part is optional, depending on your taste.

For me, finishing this mug brownie with flaky sea salt is the perfect addition. The touch of salt actually enhances the chocolate flavor and is a great contrast to the otherwise sweet vegan chocolate dessert.

Tested Substitutions

Coconut oil is my preference, but this mug cake will be just as delicious with vegetable, canola, safflower, or grapeseed oil. Bear in mind that using coconut oil will lend a very subtle coconut flavor.

Measure the oil in liquid form to get the correct amount.

Green tip: Relatively, the environmental impact of coconut oil is very low. The production of coconuts requires no herbicides or pesticides, uses little land and water, and does not require any tilling or deforestation.

For a healthier alternative, sub in 2 tablespoons + 2 teaspoons of coconut sugar for granulated sugar. You can also opt for cake flour in place of all-purpose flour in equal quantities.

Why Vegan Baking?

The mass production of eggs and dairy farming contributes a staggering amount to our overall greenhouse gas emissions and contamination of soil and water. It’s best to buy local, organic eggs and cheese when you can.

Instead, I save the egg and dairy for when it really counts. I’m talking Eggs Benedict and Cheesy Pasta.

Leaving out the dairy and eggs while baking is a great way to reduce your overall consumption of eggs and dairy. Plus, it’s just as delicious and at times, more nutritious (you know I can’t resist a good rhyme when it presents itself).

Microwaving Time May Vary

Everyone’s microwave is a little bit different. My microwave is 900 watts, and on high, this mug cake is perfect after 80 seconds.

The average microwave is between 600-1200 watts. If you know your microwave is 600 watts, you will probably need an extra 10 seconds. If your microwave is 1200 watts, start with 70 seconds.

But if you’re not sure, stick with 80 seconds. It will be safe to eat and delicious either way, but just make yourself a note for next time if you feel it was slightly overcooked.

If you’re doubling this recipe, start with 130 seconds and dip your spoon in to check if it needs any more time.

This vegan mug brownie is a dream come true. Fudgy and delicious, requires only a mug, six ingredients, and a microwave and is ready in just over 1 minute.

Ingredients

  • 2 tablespoons cocoa powder

  • 1 tablespoon all-purpose flour

  • 2 tablespoons granulated sugar

  • 2 tablespoons oil (vegetable, coconut, canola, safflower, or grapeseed)*

  • 2 tablespoons vanilla almond milk (or other milk of preference)**

  • 2 tablespoons dark chocolate chips

  • 1 pinch sea salt (optional)

Directions

  • Add cocoa powder, flour, and sugar to an 8-ounce microwave-safe mug. Use a fork to stir, ensuring there are no lumps.
  • Add milk and oil and stir well, making sure to get all the dry ingredients that may be hiding in the corners of the mug.
  • Add chocolate chips on top and microwave on high for 80 seconds. Enjoy!

Pro Tips

  • Using coconut oil does result in a mild hint of coconut flavor and aroma. If you want a strictly chocolate flavor, opt for another oil.
  • If you don’t have vanilla almond milk, you can use whatever milk is in your fridge. Option to add a splash of vanilla extract if you’re not using flavored milk.
