Ingredients

Pick up these simple ingredients the next time you're at a grocery store. See the recipe card at the bottom of this post for full ingredients, instructions, and accurate nutrition information (to the best of my ability; please consult your physician or healthcare professional if you have specific dietary needs or need to meet a certain daily value of any nutrient). I give substitutions for the ingredients in the section below this one, so most people can still make this recipe!

Wet Ingredients

• 4 Tablespoons Non-Dairy Milk: We used soy milk for our recipe, but almond milk, cashew milk, and oat milk should work just as well. Avoid coconut milk as the higher fat content may mess with the balance of the cake batter.
• 1 Tablespoon Coconut Oil
• 2 Tablespoons Salted Peanut Butter: We use a smooth peanut butter to make the cake. Of course you can use whatever kind of peanut butter you like but it may affect the final outcome since every peanut butter is different.
• 1.5 Tablespoons Granulated Cane Sugar
• 0.25 Teaspoons Pure Vanilla Extract, Optional

Dry Ingredients

• 0.25 Cup All-Purpose Flour
• 0.5 Teaspoon Baking Powder
• 2-3 Tablespoon Vegan Chocolate Chips: You can use any dairy-free chocolate chips you like! I think dark chocolate chips would be especially good in this recipe but they can be hard to find vegan for some reason.

Substitutions

• Peanut Butter: While it wouldn't be a peanut butter mug cake anymore, there are ingredients that would work in place of it. Cashew butter, almond butter, and seed butters like sunflower butter will work in place of the peanut butter. Try this recipe with my favorite chocolate hazelnut butter!
• Flour: Switch out the flour for an all purpose flour blend and it's easy to make this a gluten-free mug cake! We like King Arthur's Measure for Measure Flour or Bob's Red Mill 1:1 Gluten-Free Flour Blend.
• Cane Sugar: You could switch to a different sugar like brown sugar or coconut sugar. Alternatively, use 1 to 1.25 Tablespoons of a liquid sweetener like pure maple syrup, date syrup, or agave if you want to avoid white sugar.

How to Make a Vegan Peanut Butter Mug Cake

1. Mix the Wet Ingredients: To the bottom of a mug, add all the wet ingredients and the sugar and mix until combined with a fork, spatula, or whisk.
2. Add the Dry Ingredients: Add the flour and baking powder to the mixture and gently mix. Make sure not to over mix it!
3. Add the Chocolate Chips: Pour ⅔ of the chocolate chips into the mug and gently mix them in. Top the cake batter with the remaining chips.
4. Microwave the Mug Cake: Set your microwave to high and then cook for 1:30 to 1:45 minutes. Your cook times may differ depending on your microwave's wattage. We used a 1000 watt microwave. Keep an eye on microwave as the mug cake rises as depending on the mug it can over flow. The cake will no longer be wet and will have pulled away from the walls of the mug when done.
5. Oven Method: If you don’t have a microwave, you can still make this vegan peanut butter mug cake in an oven-safe mug or small ramekin. Bake it on the top rack of your oven at 350 degrees Fahrenheit (or 177 degrees Celsius). You’ll want to bake it for 10-16 minutes (varies by oven and a variety of other factors) or until an inserted toothpick comes out clean. Be extra careful when removing it from the oven.
6. Cool and Enjoy: Let the mug cake cool for about a minute or two. Add vegan ice cream or a drizzle of peanut butter (or other toppings) if desired and serve.
