FAQs
Can I use frozen raspberries instead of fresh?
Yes, frozen raspberries work well. Thaw them slightly and drain any excess juice before adding to the batter to prevent extra moisture.
What if I don’t have protein powder?
You can omit the protein powder and increase the flour to 5 tablespoons. The cake will be less protein-rich but still tasty.

- 3 tbsp. all-purpose flour
- 2 tbsp. vanilla protein powder
- 1/2 tsp. baking powder
- Pinch of kosher salt
Wet Ingredients
- 1 large egg
- 2 tbsp. plain whole milk Greek yogurt, plus more for serving

Other
- Cooking spray
Instructions
- Mix dry ingredients. In a small bowl, whisk together the all-purpose flour, vanilla protein powder, baking powder, and kosher salt to evenly combine the leavening agents and dry components.
- Add wet ingredients and raspberries. Crack in the egg and add 2 tablespoons of plain whole milk Greek yogurt, honey, and finely grated lemon zest. Mix all ingredients thoroughly into a smooth batter. Fold in 6 of the fresh raspberries gently to distribute without crushing them.
- Prepare the mug. Lightly spray a large microwave-safe mug with cooking spray to prevent sticking. Pour the prepared batter into the mug, spreading it evenly.
- Microwave partially. Microwave the mug cake on high for 30 seconds. This initial cook sets the batter.
- Add raspberries on top. After microwaving, use a fork to smash the remaining 4 raspberries slightly, then arrange them evenly on top of the semi-cooked batter to add extra juiciness and flavor.
- Microwave until done. Return the mug to the microwave and cook for about 30 more seconds. Check if the cake begins to pull away from the sides of the mug and if the top looks dry. If wet batter remains, continue microwaving in 10-second increments until fully cooked but moist.
- Cool and serve. Let the cake cool slightly to avoid burning. Top with additional Greek yogurt and fresh raspberries for an added creamy, fruity finish before enjoying.
Notes
- Microwave times may vary depending on the wattage of your microwave; adjust times accordingly to prevent overcooking.
- You can substitute vanilla protein powder with your preferred flavor or unflavored for variety.
- For extra moisture, add a teaspoon of unsweetened applesauce or milk if batter feels too thick.
- This recipe is best enjoyed fresh but can be stored covered in the refrigerator for up to 24 hours and reheated gently.
