🍫What you will need
📃Notes/substitutions
- Oat flour - If you do not have any on hand, you can easily make your own at home by blending some oats in a blender or food processor until finely ground.
- Cashew butter - Can be substituted with other nut butter like peanut or almond butter. For a nut-free version, use seed butter like sunflower seed butter instead.
- Milk - Any plant-based milk will work. You can even use water in place.
🔪How to make
Lightly grease a ramekin or mug with some cooking spray or oil.
Place in oat flour, chocolate chips, and baking soda. Stir to combine.
Then, add in maple syrup, cashew butter, plant milk, and vanilla extract. Mix well.
Microwave at high for 30-60 seconds, until cookie appears to be set. Let it cool down slightly before digging into your eggless mug cookie!
✔Helpful tips
- This vegan mug cookie is on the sweeter side, so feel free to reduce maple syrup used to 1 ½ tablespoons if you like it to be less sweet.
- Make sure your mug or ramekin is microwave-safe and large enough. As the cookie will expand slightly while cooking, leave some space and DO NOT fill it to the brim. A small 4-6 oz ramekin or mug should be sufficient.
- Cooking time might vary slightly depending on the modal of your microwave oven. Hence, I recommend checking on your eggless mug cookie at the 30-second mark. If it still looks undercooked, continue cooking it in 10 seconds spurt.
- Do not microwave it for too long, or your cookie might turn out to be rubbery, hard, and dry. As this recipe is eggless, you can get away with undercooking it slightly.
- It is safe to eat the raw cookie dough in this recipe.
✨Variations
Here are a few fun variations you can make to your vegan mug cookie -
Oatmeal raisin - Swap half of the oat flour with rolled oats and chocolate chips with raisins. Add in a pinch of ground cinnamon for some extra flavor.
Double chocolate - Stir in 1-2 teaspoons of cocoa powder into the cookie dough of your eggless mug cookie. You might have to add a splash more plant milk if the mixture appears dry.
Peanut butter - Replace cashew butter with peanut butter.
Molasses - Replace half of the maple syrup with molasses, and omit chocolate chips. You can also throw in a pinch of ground ginger if desired.
🍨How to serve
Although this eggless mug cookie is pretty great on its own, you can definitely pair it with something else!
- Vegan whipped cream
- A giant dollop of your favorite plant-based yogurt + more chocolate chips
- Your favorite vegan ice-cream
- Nut butter like peanut butter, cashew butter, or this coconut almond butter
- Pinch of sea salt flakes
❔Commonly asked questions
You can bake your vegan mug cookie in an oven preheated to 180C/350F for 10-12 minutes, or until set and lightly golden.
This eggless mug cookie is best eaten fresh, but leftovers can be refrigerated for 1-2 days. Make sure to cover your mug to prevent it from drying out.
