Ingredients for Fluffy Blueberry Mug Cake

This recipe makes 1 serving (use a 12 oz microwave-safe mug).

Mug Cake Ingredients:

¼ cup all-purpose flour
1 tbsp granulated sugar
¼ tsp baking powder
¼ tsp salt
3 tbsp milk (any kind)
1 tbsp butter, softened
¼ tsp vanilla extract
3 tbsp blueberries (fresh or frozen)

Optional Toppings:

Whipped cream
Greek yogurt
A drizzle of honey or maple syrup
Lemon zest

Step-by-Step Instructions

Step 1: Mix dry ingredients In a microwave-safe mug (about 12 oz), combine the flour, sugar, baking powder, and salt. Stir well until evenly mixed.

Step 2: Add wet ingredients Add the milk, softened butter, and vanilla extract. Stir until just combined — do not overmix. A few small lumps are okay for a tender texture.

Step 3: Fold in blueberries Gently fold the blueberries into the batter using a spoon. Be careful not to crush them so they stay whole and juicy.

Step 4: Microwave Microwave on high for 1 minute. Check the cake — it should be risen and look set like a baked cake. If needed, continue in 10-second increments up to a total of 90 seconds.

Step 5: Cool & serve Let the cake cool for about 1 minute (it will be very hot). Enjoy straight from the mug or top with whipped cream, Greek yogurt, a drizzle of honey, or fresh lemon zest.

Pro Tips for Perfect Fluffy Blueberry Mug Cake

Frozen Blueberries: No need to thaw them — add directly for best results.
Don’t Overmix: Overmixing develops gluten and can make the cake dense. Stir just until combined.
Microwave Variations: Every microwave is different. Start checking at 60 seconds to avoid overcooking.
Mug Size: A 12 oz or larger mug prevents overflow as the cake rises.
Extra Flavor: Add a pinch of lemon zest to the batter for a bright, fresh note that complements the blueberries.
Butter Tip: Softened (not melted) butter creates better emulsion with the milk for a fluffier result.

Variations to Try

Lemon Blueberry Mug Cake: Add ½ tsp lemon zest and a squeeze of lemon juice to the batter.
Oatmeal Version: Replace 1 tbsp flour with rolled oats for a heartier texture.
Gluten-Free: Use a 1:1 gluten-free flour blend.
Vegan: Substitute plant-based milk and vegan butter.
Protein Boost: Stir in 1 tsp vanilla protein powder (adjust milk slightly).
Mixed Berry: Combine blueberries with raspberries or chopped strawberries.
Cinnamon Spice: Add ⅛ tsp ground cinnamon for warm flavor.
