How Long do You Cook Mug Cakes?

This answer varies from Microwave to microwave, I found that this mug cake was best when microwaved for 90 seconds on 70% or medium-high power. It may require less or more time with your microwave.

A slightly under-cooked mug cake is always better than an over-cooked mug cake so err on that side of caution when you make your first one! If it gets over-cooked it will be dry and crumbly.

If it is your first time making a microwave mug cake, start with 60 seconds and check to see if it is done. Then cook at 30 second intervals until the top is firm but springy.

What Size Mug do You Need for Mug Cakes?

I would suggest using a mug anywhere in the 8-12oz. size range for this mug cake. A standard sized mug should be OK. If you use a smaller sized mug the batter will overflow as it bakes, creating a mess in your microwave.

You can also prepare this in a small bowl and split between two 6-8oz ramekins.

Ingredients for the Funfetti Mug Cake.

About the Ingredients for Vanilla Birthday Mug Cake with Sprinkles

Butter – Unsalted butter will give you the best control over the amount of salt in the recipe. If all you have on hand is salted butter, omit the added salt.

Milk – You can use any milk of your choice. Room temperature is best if you can.

Vanilla extract – Pure vanilla extract is best but artificial vanilla extract is just fine if that is all you have on hand.

Egg – We don’t need a whole egg, so just use the yolk. Save the egg white for breakfast or use in another recipe. Room temperature is best if you can.

Sugar – Plain white granulated sugar.

Flour – Spoon and level your flour so that your cake doesn’t end up dense. Never pack down flour when measuring. If you happen to have cake flour on hand, use that instead of all-purpose, it will give it more of a cake texture and flavour.

Baking powder – Leavens the cake, make sure it is fresh or still active before using.

Salt – Brings out all the flavours, omit if you use salted butter.

Sprinkles – You can use any type of sprinkle you like here, although I think rainbow sprinkles look best.
