FAQs
Can I make this without milk?
Yes! Use water or dairy-free milk like almond, oat, or soy milk.
Why is my mug cake rubbery?
Overcooking can cause a rubbery texture. Start with 60 seconds and check before microwaving longer.
Can I make this in the oven?
Yes! Bake in an oven-safe ramekin at 350°F (175°C) for 10-12 minutes.
Can I add protein powder?
Yes! Replace 1 tablespoon of flour with protein powder for a protein-packed treat.
Do I need baking powder?
No, but it helps make the cake fluffier. Without it, the cake will be denser.
Can I use flavored Oreos?
Absolutely! Try Mint Oreos, Peanut Butter Oreos, or Birthday Cake Oreos for variety.
How do I make this vegan?
Use plant-based milk and vegan Oreos (most Oreos are already dairy-free!).
Can I make this without flour?
Yes! The Oreos break down enough to form a cake-like texture without flour.
What’s the best way to crush the Oreos?
Use a fork or spoon to crush them directly in the mug, or blend for a smoother texture.
Can I double the recipe?
Yes! Use a larger mug and increase the microwave time by about 15-20 seconds.
