Chocolate Mug Cake

You know how much I love vegan mug cake recipes, right? I already shared my vegan vanilla mug cake or peanut butter mug cake before and you love them both.

Today I am back with the best vegan chocolate mug cake ever!

How to make a chocolate cake in a mug?

Mug cakes are the easiest cake to make in less than 5 minutes, preparation included. They require only basics ingredients and a microwave oven for baking. All you need to make this chocolate vegan mug cake recipe are:

  • All-purpose flour – I tested the recipe with standard wheat flour and all-purpose gluten-free flour. Both options work but the cake is dense and not as fluffy using a 1:1 all-purpose gluten-free flour blend.
  • Unsweetened cocoa powder
  • Coconut sugar – or unrefined cane sugar or erythritol for a sugar-free option. Of course, regular sugar works too. But I always prefer to use unrefined sugar options, they are healthier and higher in nutrients.
  • Olive oil – use light olive oil or avocado oil. Both are healthy low-saturated-fat oils to bake with and keep the mug cake fudgy, not dense or dry. Coconut oil works as well, but the coconut flavor is not always appreciated. I didn’t try the recipe oil-free, but I recommend using 1 tablespoon of mashed banana or applesauce to replace oil if you want to try it oil-free.
  • Baking powder
  • Vanilla extract
  • Chocolate chips – make sure they are vegan, most dark chocolate chips contains added milk so it is better to double-check the ingredient list.

Combining the dry ingredients

First, bring all the dry ingredients into a small bowl: flour, sugar, cocoa powder, baking powder, and salt. Use a whisk to combine, this prevents lumps and fine the grounded ingredients.

Stirring in wet ingredients

Now add in almond milk, olive oil, and vanilla and whisk again until the batter is smooth with no lumps. Finally, stir in chocolate chips to make a vegan chocolate chip mug cake.

This is optional, but the extra chocolate chips in the batter add a boost of sweetness and gooey texture too. I don’t recommend skipping this part.

Transferring into a microwave-safe mug

You must use a tall coffee mug to avoid the mug cake to overflow in the microwave. Make sure the coffee mug is suitable for the microwave too. Finally, sprinkle some extra chocolate chips before baking for a boost of chocolate flavor.

How to cook the cake in a microwave?

That’s the tricky part! First, check the power of your microwave. Most microwaves run between 600W and 1200W. This recipe is baked at 900W the most popular microwave heat.

It takes 90 seconds to perfectly cook this chocolate mug cake at this power.

What if I don’t’ know my microwave power?

If you are unsure of your microwave power, always start microwaving the cake for 60 seconds. Then, check the texture, if still wet in the center return to the microwave by 15 seconds burst until set. You may also want to keep the center slightly moist, to achieve a molten lava cake.

Cook time

As a general rule, this is some cooking time recommendation based on the microwave power you are using

  • At 900W – microwave for 90 seconds
  • At 1200W – microwave 60 seconds
  • At 600W – microwave 90 seconds, then test texture you may enjoy the chocolate lava center or want to return in the microwave for an extra 20 seconds to set.

How to bake mug cakes?

If you don’t have a microwave at home, you can use your oven to bake this recipe. First, make sure you are using an oven-proof ramekin. Fill the ramekin to 3/4 level and place it in the center rack of a preheated oven at 180C (350F).

Bake the mug cake for 15-20 minutes or until a skewer inserted in the center of the mug cake comes out clean or with a little to no crumb.

A mug cake baked in the oven store much longer than a microwave-baked version. You can store this cake in the pantry for 2-3 days, covered with a silicon lid to avoid the top to dry out.

How to store mug cakes?

Unfortunately, you can’t store mug cakes baked in your microwave. Microwave is a fast cooking process that dehydrates food quickly.

While it is a convenient method to cook a cake in less than 2 minutes, it allows dry out the ingredients quickly.

Therefore, a mug cake shouldn’t be baked in advance and eat straight away from the mug to enjoy its best texture.

However, you can make ahead the mug cake batter, store in the fridge, and microwave just before serving.

How to serve this vegan mug cake?

A microwave mug cake is better served immediately, straight away from the mug. You can also flip it over a plate too but it won’t look as beautiful. The best vegan toppings are:

  • Vegan ice cream
  • Vegan whipped coconut cream
  • A dollop of peanut butter or almond butter

Ingredients

Instructions

  • In a small mixing bowl, whisk flour, unsweetened cocoa powder, coconut sugar, baking powder, and sea salt until combined.
  • Add olive oil, almond milk, and vanilla. Whisk until smooth.
  • Stir in chocolate chips if desired.
  • Transfer the batter into a tall microwave-safe coffee mug and sprinkle few extra chocolate chips on top.
  • Microwave for 80-90 seconds at 900W or until cook on top, no runny in the center. You can return to the microwave by 10 seconds burst if undercooked. Also, if your microwave works at a lower power, you may have to increase baking time by 20 seconds bursts. If your mug is low and wide, your mug cake will bake faster and you may have to bake only 60 seconds first then adjust baking by 20 seconds burst.
  • Enjoy immediately, mug cake baked in the microwave doesn't store well.

Notes

Sugar-free option: replace sugar with the same amount of erythritol and use sugar-free chocolate chips.
Gluten free flours: you can use all-purpose gluten-free flour but the cake won't raise ! Gluten is the active ingredient that raise cake when combined with baking powder, so any gluten-free flour will make this cake flat and dense.

    Hello, thank you for this recipe! What size ramekin should I use if I am baking this cake and could I substitute the coconut sugar for date sugar?

  2. liz

    does it actually rise? ive used it with gluten free flour and also randomly tried chickpea flour and both dont rise. They just go up about a centimetre or 2, is this what is supposed to happen?

    • Carine

      Gluten free flour never raise as gluten is the active ingredients that react with baking powder and raise cakes. This recipe has been create for all-purpose flour, it contains gluten and therefore the cake raise with it. The flours you used are gluten free so they can’t raise. Enjoy, XOXO Carine
