How to make a 3 Ingredient Mug Cake
Ingredients:
- 4 tablespoons all-purpose flour (sifted for best results)
- 2 tablespoons granulated sugar
- 2 tablespoons unsweetened cocoa powder (Dutch-processed optional)
- 4–5 tablespoons milk (use plant-based milk for a dairy-free option)
- ¼ teaspoon vanilla extract (optional, but highly recommended for that extra warmth)
Directions:
- Start by lightly spraying your microwave-safe mug with cooking spray. This little step will ensure your cake slides right out, just like Grandma used to do.
- In that same cozy mug, combine the flour, sugar, and cocoa powder. Stir them together until they blend smoothly, akin to a gentle Southern breeze.
- Gradually pour in the milk, stirring as you go until the batter is consistent. Just imagine it, thick, rich, and oh-so-chocolatey!
- Place the mug in the microwave and cook on high for 60 to 90 seconds. After that, check doneness with a toothpick; it should come out clean—not a stray crumb in sight!
How to serve a 3 Ingredient Mug Cake
When it’s piping hot, you can enjoy it as-is or dress it up even more. A dollop of whipped cream or a sprinkle of powdered sugar adds a touch of elegance. You could even toss in some chocolate chips before microwaving—because some days, you just need a little extra chocolate love.
How to store a 3 Ingredient Mug Cake
If there are any leftovers (unlikely, I know!), let the mug cake cool completely and cover it tightly with plastic wrap or store it in the fridge for a day. Reheating it in the microwave for a few seconds will have it feeling cozy again.
Tips to make a 3 Ingredient Mug Cake
- For the fluffiest texture, make sure to sift the flour.
- Adjust the milk based on how moist you like your cake—add a little more for a richer experience.
- Feel free to experiment! A pinch of cinnamon or a scoop of peanut butter can transform your mug cake into something uniquely yours.
Variations
- If you’ve got a sweet tooth for fruity treats, add in some chopped strawberries or a handful of blueberries.
- For a nutty twist, try a tablespoon of finely shredded coconut or some chopped walnuts—both offer a delightful crunch and flavor.
