Ingredients for vegan mug brownies.


  • Water + ground flax – This replaces the eggs in traditional brownie recipes.
  • Applesauce – This helps to add moisture and a touch of sweetness to the brownies without overpowering the flavor
  • Maple Syrup – provides sweetness and helps keep the brownies rich and dense.
  • Cacao powder (or cocoa powder) – gives that deep chocolate flavor to the brownies
  • Baking Powder – to help give the brownies some lift during cooking
  • Peanut butter, almond butter, sunflower seed butter – this is the key to getting fudgy brownies out of the microwave.
  • Strawberries – optional but so good.
  • Cacao nibs or chocolate chips (optional) – this will take the brownies to the next level!

How to make these easy vegan brownies

Step 1: Start by mixing together the water, ground flax, applesauce, maple syrup and cacao powder. This will take a minute or so to fully combine, just keep mixing.

Step 2: Add the peanut butter to the mixture and stir well until fully combined. This will take 1-2 minutes.

Step 3: Add the chopped strawberries. You can also add in any other mix in’s (cacao nibs, chocolate chips, coconut flakes) you want now as well.

Step 4: Divide the brownie mixture between 2 ramekins. Microwave each brownie for 1:30 on high or bake in a 350F oven for 20 minutes.

If you love single serving desserts

Even though most of my recipes are packed with really healthy ingredients, I can quickly go overboard with servings, especially when it comes to sweets.  

I love single serving desserts, they help me control my portions while feeling fully satisfied by getting to eat “the whole thing”. I’m not really good at portion control when I’m staring down a plate of brownies.

If you are the same way, you might enjoy some of my other favorite single serve desserts including:

Common questions

How to make brownies without eggs

You can use ground flax seeds or chia seeds to help bind and set the batter to make brownies without eggs.

Can you use frozen strawberries

I suggest using fresh strawberries since frozen strawberries are often not as sweet as fresh strawberries and they tend to give off a lot of extra water when cooking.

If you want to use frozen strawberries, make sure they are defrosted first, and you might want to add a small sprinkle of coconut sugar to the strawberries to help sweeten them.

Other fruits that would be good in these brownies

  • Raspberries (fresh or frozen)
  • Sweet cherries (pitted or defrosted from frozen)

What other mix-in’s can you add

What kind of ramekins to use

I have made this recipe using coffee mugs, regular bowls, glass ramekins, traditional ceramic ramekins and these fun square ramekins. When using traditional ramekins, the center of these really stays gooey and fudgy. The edges of the square ramekins can overcook in the oven but stay nice and gooey in the microwave. 

How to make a cakey single serve brownie

These gluten free microwave brownies are pretty fudgy and dense. If you love a brownie that has a more cake like flavor, add 1 1/2 tablespoons of gluten free flour to the mix before stirring. This will make the perfect mug cake brownie.

How to store single serve brownies

Fridge: This recipe makes 2 brownies, so if you are by yourself, make both and store the leftover in the fridge for up to 4 days. You will want to cover the ramekin/mug so the brownies don’t dry out.

Freezer: You could freeze these brownies in the ramekins or mugs but that means you won’t have your ramekin/mug for some time. If you are trying to freeze brownies for later, it’s probably best to make a big batch and freeze individual servings.


  • Ground flax + water: You could also use chia seeds for this. The flax replaces a single egg so if you are not vegan/egg free, you could use 1 egg in place of the flax + water.
  • Applesauce: I like using applesauce because it does not overpower the flavor of the brownies. You could also use mashed banana or mashed sweet potato in place of the applesauce. Just note that the banana may add a little banana flavor to the brownies.
  • Maple syrup: This makes the brownies sweet and fudgy. You could also use a low sugar monk fruit based syrup if you are trying to keep your carbs down. Other options are honey or date syrup. I tried this with coconut sugar and the brownies dried out and were crumbly so I don’t recommend that.
  • Cacao powder: I like cacao powder over cocoa powder because the cacao is less bitter. However if cocoa powder is all you have, you can use that in place of the cacao.
  • Baking powder: This is optional but if you have it on hand, it does help the brownies rise a bit while cooking.
  • Peanut butter: What makes these brownies thick and fudgy is the nut butter added. You could use peanut butter, tahini, sunflower seed butter, almond butter or cashew butter in this recipe and they will all work well.
  • Strawberries: Use fresh or frozen, be sure to cut them into small pieces to easily incorporate into the brownies. You could also use raspberries or sweet cherries in place of the strawberries. You can also omit the fruit completely and just make brownies without fruit.
