Can I use chocolate frosting instead of vanilla?

Why did my mug cake turn out rubbery?
A rubbery texture is usually a result of overcooking. Try reducing the microwave time by 15-20 seconds next time.
Can I double the recipe in a single mug?
It is better to make two separate batches to ensure even cooking and prevent the batter from overflowing.
What size mug should I use?
A standard 12-ounce microwave-safe mug is recommended to allow the cake enough room to rise without spilling.
Can I use honey instead of sugar?
Yes, honey or maple syrup can be used, though it may result in a slightly denser cake texture.
Is the frosting necessary for the recipe?
The frosting is optional but highly recommended for the full 'celebration' experience and extra sweetness.
How do I know when the cake is finished cooking?
The cake should have risen significantly and the top should feel firm to a gentle touch.
Can I add nuts to the batter?
Yes, you can fold in a tablespoon of chopped nuts like walnuts or pecans for added crunch.
Why did my mug cake fail to rise?
This usually happens if the self-rising flour is expired or if the leavening agents were not properly incorporated.
Can I store leftovers of this mug cake?
It is best enjoyed immediately, but you can cover it and store it at room temperature for up to 24 hours.
Is this recipe safe for children to make?

What is the total preparation time?
Preparation takes about 1 minute, and cooking takes about 2 minutes, totaling under 3 minutes.
Do I need to grease the mug before adding batter?
It is not strictly necessary due to the oil in the recipe, but a light coating of cooking spray makes cleanup easier.
Can I make a chocolate version of this?
Yes, you can replace one tablespoon of the flour with cocoa powder to create a chocolate mug cake.
What can I use instead of vanilla extract?
You can substitute with almond extract, maple extract, or simply omit it if none is available.
Can I use brown sugar instead of white sugar?
Yes, brown sugar will add a deeper, caramel-like flavor and slightly more moisture to the cake.
Is this recipe nut-free?

Can I skip the sprinkles inside the batter?
Yes, you can skip them for a plain vanilla mug cake or just use them as a topping after frosting.
What is the texture of a mug cake?
It has a soft, sponge-like texture that is slightly more moist and dense than a traditionally baked oven cake.
