In a microwave-safe mug, add softened butter and sugar. Cream together with a spoon until light and fluffy.
Add all-purpose flour and baking powder. Gently fold until combined.
Pour in warm milk and vanilla extract. Stir until smooth and lump-free, scraping the sides and bottom of the mug.
Microwave on high (900W) for 50–60 seconds, until the cake has risen and the top looks set but still moist inside.
Let the mug cake rest in the microwave for 1 minute to finish cooking evenly.
Beat cream cheese and butter together until smooth and creamy.
Add powdered sugar and vanilla, mix until light and fluffy. Taste and adjust sweetness if needed.
Spread or pipe frosting over the cooled mug cake.
Add chocolate chips, caramel bits, or fruit chunks into the batter for fun flavor twists.
For a lighter texture, don’t overmix the batter.
Replace butter with coconut oil for a dairy-free version.
Cook at 900W for 50–60 seconds. If using a lower watt microwave, add 10–15 seconds.
Do not overcook — it continues to set as it cools.
Can I make this mug cake gluten-free?
Yes, you can use oat flour or gluten-free flour as a substitute for all-purpose flour to make it gluten-free.
How can I make this recipe dairy-free?
You can replace butter with coconut oil and use a dairy-free milk alternative to make this recipe dairy-free.
What can I use instead of sugar?
You can use coconut sugar or honey as a natural sweetener instead of regular sugar.
Why is my mug cake dense?
If your mug cake is dense, it might be because the batter was overmixed. Mix just until smooth to avoid this.
How do I store the mug cake?
This mug cake is best enjoyed fresh, but if frosted, you can store it covered in the fridge for up to 12 hours and reheat for 10 seconds before serving.
