Vegan Chocolate S’mores Mug Cake

Summer is just around the corner; what better way to celebrate than to try out this spin on a classic summertime s’more treat. This Vegan Chocolate S’mores Mug Cake is quick and easy to make and can satisfy your sweet tooth in 5 minutes!

To ensure that this recipe is vegan we used vegan marshmallows. The majority of marshmallows are made with gelatin, which is derived from animal collagen, however, vegan marshmallows like these are a great alternative for those following a vegan diet. 

But it’s not just the marshmallows that make this dessert vegan-friendly; the entire recipe is crafted without any animal products! Instead of traditional milk chocolate and graham crackers, we opted for dairy-free dark chocolate chips and vegan graham crackers. 

The beauty of this Vegan Chocolate S’mores Mug Cake lies in its simplicity and convenience. With just a handful of pantry staples and a microwave, you can whip up a decadent single-serving dessert in no time. Whether you’re spending a long weekend at the cottage, roasting marshmallows over a campfire, or simply enjoying a quiet evening at home, this Vegan Chocolate S’mores Mug Cake is the perfect indulgence.

So, gather your ingredients, grab your favorite mug, and get ready to indulge in the irresistible combination of rich chocolate, fluffy marshmallows, crunchy graham crackers, and let this recipe be the sweet highlight of your summer adventures!

Storage Tips: 

While this recipe is designed for a single serving indulgence, if you find yourself with leftovers, fear not!

When ready to enjoy again, gently reheat in the microwave for a few seconds until warm and gooey, and savor the deliciousness all over again.

Vegan Chocolate S’mores Mug Cake Recipe Variations and Substitutes:
