Recipe Tips

Don’t overmix the batter – Stir just until everything is combined for a tender texture.
Adjust the sweetness – If you like it sweeter, add an extra teaspoon of sugar.
Fresh or frozen blueberries? – Both work! If using frozen, no need to thaw, but expect a slightly longer cook time.
Mug matters – Use a microwave-safe mug that holds at least 10-12 ounces to prevent overflow.
Test for doneness – If the cake looks slightly undercooked after 60 seconds, microwave in 10-second intervals until fully set.

What to Serve with Blueberry Mug Cake

This Blueberry Mug Cake is delicious on its own, but pairing it with the right toppings or sides can take it to the next level! Here are some tasty ideas:

🍦 Ice Cream – A scoop of vanilla, lemon, or blueberry ice cream adds a creamy contrast to the warm cake.
🍯 Drizzles – Try honey, maple syrup, or a light dusting of powdered sugar for extra sweetness.
🥄 Whipped Cream – A dollop of fresh whipped cream makes it feel extra indulgent.
🍋 Lemon Zest – A sprinkle of lemon zest or a squeeze of lemon juice enhances the fruity flavors.
🫐 More Berries – Serve with extra fresh blueberries, raspberries, or sliced strawberries.
🥜 Nut Butter – A drizzle of almond, peanut, or cashew butter adds a rich, nutty flavor.
☕ Beverages – Pair with coffee, tea, or a glass of cold milk for the perfect treat.
