Ingredients You’ll Need
Nothing fancy here—just your usual baking besties plus a few fun extras. All stuff you probably already have chilling in your kitchen.
- 4 tablespoons all-purpose flour – the base of all good things
- 2 tablespoons granulated sugar – sweet, like you
- ¼ teaspoon baking powder – gives it lift so it’s not sad and dense
- Pinch of salt – trust me, it matters
- 3 tablespoons milk – dairy or plant-based, both work
- 1 tablespoon melted butter – for flavor (can sub oil if you must)
- ¼ teaspoon vanilla extract – makes it taste like actual cake
- 1 tablespoon rainbow sprinkles – non-negotiable
- Optional: extra sprinkles for topping, because ✨vibes✨
Step-by-Step Instructions
- Grab your favorite mug.
Choose one that’s microwave-safe and holds at least 10–12 oz. Bigger is better—no one likes mug lava. - Mix the dry stuff.
Add flour, sugar, baking powder, and salt right into the mug. Stir with a fork like a baking rebel. - Add the wet ingredients.
Pour in milk, melted butter, and vanilla. Stir again until smooth. Don’t overthink it—no one’s judging your technique. - Sprinkle in the fun.
Fold in the rainbow sprinkles. Don’t skip this. Life is hard; your cake shouldn’t be. - Microwave that beauty.
Heat on high for 60 to 75 seconds, depending on your microwave’s mood. It should puff up and look set on top. - Cool (slightly) and top.
Let it sit for a minute unless you enjoy burning the roof of your mouth. Add extra sprinkles, whipped cream, or ice cream if you’re feeling extra.
Common Mistakes to Avoid
- Overcooking it.
If you zap it too long, it’ll turn into a rubbery sponge of sadness. Start with 60 seconds and check from there. - Using too small of a mug.
Overflow = microwave disaster. Go big or…clean up later. - Leaving out the salt.
It sounds skippable, but salt makes the vanilla flavor pop. Don’t be that person. - Adding too many sprinkles.
Yes, that’s possible. Too many = weird texture. Stick to about a tablespoon inside the batter. - Microwaving with metal.
Just… no. Your mug should not have a metallic rim. Let’s not set anything on fire today.
Alternatives & Substitutions
- No butter?
Use neutral oil like canola or even coconut oil. Butter gives better flavor, but cake is cake. - Vegan?
Use plant milk and oil. Done. It still tastes like a sweet little dream. - Gluten-free?
Use a 1:1 gluten-free flour blend. Mug cakes are forgiving. You’ll still get fluff. - No sprinkles?
Sub chocolate chips, crushed Oreos, chopped nuts—whatever makes your heart sing. - Want it richer?
Add a spoonful of sour cream or Greek yogurt for extra moisture. You fancy.
FAQ (Frequently Asked Questions)
Can I make this without a microwave?
Technically yes, but it’s not ideal. You can bake it in the oven at 350°F for about 10–12 minutes, but honestly? That kind of defeats the whole lazy genius vibe.
What kind of mug should I use?
Go for ceramic, 10–12 oz, microwave-safe. If it’s too small, you’ll end up with cake overflow and probably tears.
Why does my cake look wet on top?
It’s probably fine. Mug cakes keep cooking for a few seconds after microwaving. If it’s super gooey, give it another 10 seconds max.
Can I double the recipe?
Not in one mug. Trust me. The bottom will be raw and the top will explode. Make two separate mugs if you want to share—or not.
Do I need to grease the mug?
Nope, not unless you want to pop the cake out onto a plate. Otherwise, just eat it straight from the mug like a champion.
Is this a real cake or just pretending?
It’s real. Is it bakery-level? No. Is it warm, sweet, and cake-y enough to satisfy your 9pm cravings? Absolutely.
