Okay, picture this: its late. You’re curled up on the couch, binge-watching your favorite show (currently obsessed with 'The Great British Baking Show,' btw!). That sugar craving hits HARD. But the thought of baking a whole cake? Absolutely not. Been there, felt that, right? That's precisely when the Salted Caramel Swirl Mug Cake enters the scene – your single-serving savior.

This isn't just any mug cake; it's an experience. The warmth of the cake, that gooey caramel ribbon dancing through every bite, and a whisper of salt that just elevates everything? It's pure comfort, pure joy, and ridiculously easy to whip up. Honestly, I think it's better than those complicated recipes i've tried. Trust me, your taste buds will thank you. Oh! I almost forgot to tell you about my friend Sarah’s hilarious attempt to make a soufflé last Thanksgiving. It deflated before it even left the oven! But this mug cake? Foolproof, even for Sarah.

So, what makes this mug cake so special? It's all about balance. The sweetness of the caramel is perfectly offset by the touch of sea salt, creating a symphony of flavors that dances on your tongue. The texture is spot-on too - moist, tender, and with just the right amount of crumb. Plus, it’s endlessly customizable! Add a sprinkle of chopped nuts, a dollop of whipped cream, or even a scoop of ice cream for the dessert of your dreams. What could be better than that? Nothing, I tell you!

🍽 Ingredients

📖 Instructions

  1. Grab your favorite mug: A standard 12-ounce mug works perfectly for this recipe.
  2. Melt the butter: In the mug, melt 2 tablespoons of unsalted butter in the microwave. This usually takes about 20-30 seconds, but keep an eye on it to prevent splattering.
  3. Add the sugar: Stir in 2 tablespoons of granulated sugar and 1 tablespoon of packed brown sugar into the melted butter. Mix well until combined.
  4. Incorporate the egg yolk: Add 1 large egg yolk to the mug and whisk vigorously until the mixture is smooth and slightly lightened in color.
  5. Add vanilla extract: Stir in 1/4 teaspoon of vanilla extract for added flavor.
  6. Combine dry ingredients: In a separate small bowl, whisk together 1/4 cup of all-purpose flour, 1/4 teaspoon of baking powder, and a pinch of salt.
  7. Gradually add dry ingredients to wet: Add the dry ingredients to the wet ingredients in the mug, mixing until just combined. Be careful not to overmix; a few small lumps are okay.
  8. Prepare the caramel swirl: Drizzle 2 tablespoons of salted caramel sauce over the batter in the mug. Use a knife or skewer to gently swirl the caramel into the batter, creating a marbled effect.
  9. Microwave the mug cake: Microwave on high for 60-90 seconds, or until the cake is cooked through. Cooking times may vary depending on your microwave, so start with 60 seconds and add more time in 10-second intervals if needed. The cake should be puffed up and slightly firm to the touch. If it is still liquidy, cook for a little longer.
  10. Let it cool slightly: Allow the mug cake to cool for a minute or two before serving. This will help prevent it from being too hot and allow the flavors to meld together.
  11. Garnish and serve: Sprinkle a pinch of sea salt over the top of the mug cake for that signature salted caramel flavor. You can also add a dollop of whipped cream or a scoop of vanilla ice cream, if desired. Grab a spoon and enjoy your Salted Caramel Swirl Mug Cake while it's still warm!

📝 Notes

  • Microwave cooking times may vary; adjust as needed.
  • Feel free to add chopped nuts or whipped cream for extra indulgence.
