How to Make the Perfect Salted Caramel Mug Cake
Whisk Together: In a microwave-safe mug, whisk together the all-purpose flour, granulated sugar, and baking powder until they are well combined. This will form the base of your delicious cake.
Mix Ingredients: Stir in the melted unsalted butter, milk, egg, and vanilla extract. Combine these ingredients until you have a smooth batter that's ready for the next step.
Add Caramel: Swirl a generous amount of caramel sauce into the batter. Be careful not to mix it in completely; you want those beautiful streaks of caramel throughout.
Top with Salt: Sprinkle a pinch of flaky sea salt on top of the batter. This will enhance the flavor and contrast beautifully with the sweetness of the caramel.
Microwave: Place the mug in the microwave and cook on high for 90 seconds. Keep an eye out for the cake as it rises; you want to catch it just as it sets.
Cool and Serve: Once done, let the cake cool for a few minutes. Top it with additional caramel sauce and a sprinkle of sea salt for that extra indulgence before diving in.
Optional: Serve with a scoop of vanilla ice cream or a dollop of whipped cream for an extravagant treat!
