Why You'll Love This Chocolate Peanut Butter Mug Cake
- Super quick: It literally only takes a few minutes to make this vegan cake.
- Made for one: This is a great option when you want to satisfy your chocolate craving but you don't want to make an entire cake or pan of brownies.
- No bowls needed: You only need a mug so cleanup couldn't be easier!
- Chocolate + peanut butter: The perfect combination.
Ingredient Notes
- Flour - I use regular all purpose flour.
- Sugar - I prefer using white sugar but you can do brown as well for a little molasses flavor.
- Oil - I recommend using regular vegetable oil or canola oil as they have a very neutral flavor.
- Non-dairy milk - I use unsweetened soy milk for all my baking and cooking. Almond milk and oat milk would work well too. Coconut milk will add a coconut flavor to your cake.
- Vegan chocolate chips - Any kind you can find works. I like using Trader Joe's Chocolate Chips which are accidentally vegan.

Variations
I like this recipe as written but feel free to mix it up a bit.
- A la mode - Add a scoop of vegan vanilla ice cream on top!
- Super chocolatey - If you don't like peanut butter you can leave it out and just have a very chocolatey cake.
- Nutty flavor - Instead of peanut butter, you can substitute almond butter or sunflower butter. You can also add in some chopped nuts.
- Mug cake sundae - Add some non-dairy whipped cream on top and some sprinkles.
- Caramel - Add a drizzle of vegan caramel on top.
How To Make Vegan Chocolate Peanut Butter Mug Cake
This easy recipe uses simple ingredients and a microwave-safe mug. That's right...no other bowls needed!

Step 1: To begin, put the flour, sugar, cocoa powder, baking powder and salt in a mug and whisk together.

Step 2: Now it's time for the wet ingredients. Add the oil, non-dairy milk, and vanilla extract to the dry ingredients and mix well. It should resemble regular chocolate cake batter.

Step 3: For the peanut butter, you want to keep it together in one piece instead of swirling it in. I use two spoons to put the peanut butter in the middle of all the batter. You'll want to make sure it's submerged in the chocolate.

Step 4: Put your chocolate chips on top. You do not need to mix it in. I love a lot of gooey chocolate and peanut butter but you can also use less chocolate chips if you prefer.

Step 5: Cook the mug cake in your microwave for 1 minute. Let it cool for a minute or two before digging in. It will be very chocolatey!
Expert Tips
- When you are mixing the batter, make sure you incorporate all the ingredients right down to the bottom of the mug. You don't want to have a clump of flour at the bottom.
- I prefer to eat it right out of the mug but you can also transfer it to a plate. It's not super attractive but it tastes amazing.
Love peanut butter? If so, try my vegan fluffernutter cookies. They're the delicious combination of peanut butter and marshmallow.
Storage Tips
This vegan chocolate peanut butter mug cake is best eaten right after making it. Do not try to store this mug cake and then reheat it.
Recipe FAQs
I like using regular vegetable or canola oil. Sunflower oil is another good neutral option. Melted coconut oil could work too but it will give some coconut flavor.
I only make mug cake with regular all purpose flour. But if you want to experiment with whole wheat or oat flour, try just substituting 1-2 tablespoons of the regular flour. Let me know how it turns out!
Sure! Using an alternative sugar will just change the flavor a bit but it will still work out. Brown sugar will give it a light molasses flavor.
Not at all. I like an all natural peanut butter without added oil and sugar but use your favorite brand.
