Step‑by‑Step Instructions for Blueberry Mug Cake
Step 1: Combine Dry Ingredients
In a microwave-safe mug, add 4 tablespoons of all-purpose flour, 2 tablespoons of sugar, 1/8 teaspoon of baking powder, and a pinch of salt. Use a small whisk or fork to blend these dry ingredients until evenly mixed, ensuring no clumps remain. This combination sets the foundation for your Blueberry Mug Cake, creating a light and fluffy texture when cooked.
Step 2: Mix in Wet Ingredients
Next, pour in 3 tablespoons of milk, 1 tablespoon of softened butter, and 1/4 teaspoon of vanilla extract into the mug. Stir the mixture gently until everything is just combined, taking care not to overmix as this can affect the cake’s fluffiness. The batter should form a thick, smooth consistency, ready to receive those delicious blueberries.
Step 3: Fold in Blueberries
Gently fold in 2 tablespoons of blueberries into the batter, ensuring they’re evenly distributed. Be careful not to crush the berries as they will add moisture and flavor to your Blueberry Mug Cake. The vibrant color from the blueberries will make your cake visually appealing, signaling that it’s time for a quick treat.
Step 4: Microwave the Cake
Place the mug in the microwave and cook on high for 1 minute. After the time is up, check the texture; the cake should look set and slightly spring back when tapped. If it’s still wet in the center, microwave in additional 10-second increments until fully cooked but be cautious not to overdo it, as cooking times can vary.
Step 5: Let It Cool
Once cooked, remove the mug from the microwave (it will be hot!) and let it cool for about 1 minute. This brief cooling period allows the flavors to settle while the cake firms up slightly. Your Blueberry Mug Cake should now be ready to indulge in a warm, sweet moment from your own personalized dessert. Enjoy directly from the mug!
