Essential Ingredients for the Recipe
Ingredients
- 4 tbsp all-purpose flour
- 2 tbsp granulated sugar
- 1/4 tsp baking powder
- Pinch of salt
- 3 tbsp milk (dairy or plant-based)
- 1 tbsp vegetable oil or melted butter
- 1/4 tsp vanilla extract
- 2 tbsp forest blueberries (fresh or frozen)

Forest Blueberries
The star of the show! Forest blueberries are smaller and more intense in flavor than regular blueberries, giving this mug cake a unique, fruity burst. If you can’t find forest blueberries, regular blueberries or even frozen ones work just as well.
Flour
All-purpose flour is the base of this recipe. For a gluten-free version, you can substitute it with almond flour or a gluten-free flour blend.
Milk
Milk adds moisture and richness. Use dairy or plant-based milk like almond, oat, or soy milk depending on your preference.
Ingredient Preparation
Step 1 – Gather Your Ingredients
Before beginning, ensure all your ingredients are measured and prepared. This helps maintain a smooth process and avoids any last-minute rushing.
Step 2 – Prep the Blueberries
If using fresh blueberries, rinse and pat them dry. For frozen blueberries, there’s no need to thaw—just toss them in straight from the freezer.
Step 3 – Mix Dry Ingredients First
Combine the flour, sugar, baking powder, and a pinch of salt in your mug. This ensures even distribution and a perfectly fluffy texture.
Step-by-Step Cooking Instructions
Step 1 – Mix the Batter
Add the milk, oil (or melted butter), and vanilla extract to the dry ingredients. Stir until just combined—don’t overmix!
Step 2 – Add the Blueberries
Gently fold in the blueberries, making sure they’re evenly distributed throughout the batter.
Step 3 – Microwave and Enjoy
Microwave on high for 1–2 minutes, adjusting based on your microwave’s power. The cake is ready when it has risen and is set on top. Allow it to cool for a minute before enjoying it.
Tips for an Even Tastier Version
Adding Extra Ingredients
Try adding a sprinkle of cinnamon, a handful of chocolate chips, or a dollop of nut butter for extra flavor.
Techniques to Enhance Flavor
Drizzle honey or maple syrup on top for added sweetness, or add a scoop of vanilla ice cream for a decadent twist.
Adjustments for Preferences
For a vegan version, use plant-based milk and a flax egg. For a low-carb option, swap sugar with a keto-friendly sweetener.
Recipe Variations and Adaptations
Gluten-Free Option
Substitute all-purpose flour with almond flour or a gluten-free alternative.
Vegan Option
Use plant-based milk and a flax egg (1 tbsp ground flaxseed + 3 tbsp water).
Seasonal Variations
Swap blueberries for other fruits like raspberries, diced apples, or even banana slices depending on the season.
Serving Suggestions
Toppings Galore
Top your mug cake with whipped cream, a dusting of powdered sugar, or a handful of fresh berries.
Pair with a Drink
Enjoy your mug cake with a cup of herbal tea, a glass of cold milk, or even a latte for a cozy treat.
