How to Make Blueberry Vanilla Mug Cake
Combine ingredients: In a microwave-safe mug (10-12 oz), whisk together all-purpose flour, granulated sugar, baking powder, and salt until they're nicely mixed and there are no lumps.
Mix wet ingredients: Add in the milk, melted butter (or your choice of oil), and pure vanilla extract; stir everything together until it’s smooth and lump-free, creating a delightful batter.
Fold in blueberries: Gently fold the blueberries into the batter, taking care to create a marbled effect without overmixing; this ensures those juicy pockets of blueberry goodness shine through!
Microwave: Place your mug in the microwave and cook on high for 1 minute and 30 seconds to 2 minutes. Check for doneness; the cake should rise and appear set, resembling a fluffy dream.
Let cool and serve: Once cooked, allow it to cool for 1-2 minutes. Top your delightful cake with more blueberries and a sprinkle of coarse sugar or a drizzle of custard for an extra touch of sweetness.
