The image shows two white cups filled with a soft, light yellow cake layer that looks moist and fluffy. On the top layer, there are bright red raspberry pieces embedded, adding texture and color. In the center of each cup, there is a dollop of white cream with a few fresh whole raspberries placed on top. Around the cups on the white marbled surface, there are some loose fresh raspberries scattered for decoration. The light hits the cups softly, highlighting the natural colors and textures of the dessert, photo taken with an iphone --ar 4:5 --v 7

Ingredients

3 tbsp. all-purpose flour
2 tbsp. vanilla protein powder

1/2 tsp. baking powder
Pinch of kosher salt

1 large egg
2 tbsp. plain whole milk Greek yogurt, plus more for serving

2 tsp. honey
1 tsp. finely grated lemon zest
10 fresh raspberries, divided, plus more for serving

Cooking spray

Instructions

Step 1: In a small bowl, whisk together the flour, protein powder, baking powder, and salt. Add the egg, 2 tablespoons of Greek yogurt, honey, and lemon zest, mixing until smooth. Gently fold in 6 raspberries.
Step 2: Lightly spray a large microwave-safe mug with cooking spray. Pour the batter into the mug.

Step 3: Microwave the batter for 30 seconds. Using a fork, gently mash the remaining 4 raspberries and arrange them on top of the batter.
Step 4: Continue microwaving until the cake starts to pull away from the sides of the mug and the top looks dry, about 30 seconds more. If the top is still wet, microwave in additional 10-second increments. Allow the cake to cool slightly.
Step 5: Serve topped with extra Greek yogurt and fresh raspberries for added flavor and creaminess.

Tips & Variations

For a dairy-free option, substitute the Greek yogurt with coconut yogurt and use a plant-based milk instead of regular milk.
Swap raspberries for blueberries or chopped strawberries for a different berry twist.
If you prefer a sweeter cake, add a little more honey or a drop of vanilla extract.

Make sure to use a large enough mug to prevent the batter from overflowing while microwaving.

Storage

It’s best to enjoy this mug cake fresh, as the texture may change upon storing. If you have leftovers, cover the mug tightly and keep it in the refrigerator for up to 1 day. Reheat in the microwave for 15–20 seconds before serving, adding a little extra yogurt if desired.

How to Serve

Three white mugs each hold a single-serving yellow cake with a soft texture. Each cake is topped with a dollop of white cream in the center, surrounded by bright red crushed raspberries spread unevenly across the top. Whole fresh raspberries are placed on the cream, adding three-dimensional detail and a contrasting red color. Some loose raspberries rest on a white marbled surface near the mugs. A spoon is partially inside one mug, breaking the cake to show its moist interior. The overall scene is bright and colorful, with smooth and textured elements in a simple and clean setting. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use a different protein powder?

Yes, you can substitute vanilla protein powder with any flavored or unflavored protein powder you have on hand. Adjust sweeteners as needed based on the flavor.

What if I don’t have fresh raspberries?

If fresh raspberries aren’t available, frozen raspberries can be used. Just thaw them first and drain any excess moisture to avoid a soggy cake.
