We have been making mug cakes for a couple of years now, and it takes a little work to find the perfect balance of ingredients. This is not the type of recipe where you want to wing it! Definitely find a good recipe and use it! You also want to make sure to use a microwave-safe mug or ramekin and you do not want to overcook it!

I love mug cakes. They are simple, quick, and satisfy your sweet cravings. We make mug cakes year-round and I know that this peanut butter cookie version will definitely be added to our rotation! After making these Healthier Peanut Butter Cup Mini Pies , I have been experimenting with other non-dairy dessert recipes, and was able to make this Microwave Mug Cake non-dairy! I swapped out regular milk for almond milk, which worked perfectly! The nutty almonds complimented the peanut butter so well. If you are not concerned about your dairy intake, feel free to use regular milk!

You can’t have dessert without whipped topping, and I was so excited to find this Reddi-wip® at Walmart that is made with almond milk! It is deliciously creamy, gluten-free, and vegan. It has all the cravable flavors of regular Reddi-wip® without dairy, artificial flavors, or artificial sweeteners. It tastes great on any dessert, fruit, or even a dollop in your morning coffee! I actually think I like it even better than regular whipped cream!
