The top is thickly swirled with creamy white icing that is smooth and slightly glossy, lightly melting into the warm roll. There are some crumbly bits scattered on the surface and edges where the roll meets the mug. The mug sits on a white marbled surface, and a slightly blurred silver spoon lies beside it on the left. photo taken with an iphone --ar 4:5 --v 7

Ingredients

1/4 cup vanilla or unflavored protein powder
2 tablespoons oat flour or almond flour for gluten-free
1/2 teaspoon baking powder
1/2 teaspoon ground cinnamon
Pinch salt
1 large egg
3 tablespoons unsweetened almond milk or milk of choice
1 tablespoon maple syrup or honey
1/2 teaspoon vanilla extract
1 teaspoon coconut oil or melted butter
1 teaspoon brown sugar or coconut sugar
1/2 teaspoon ground cinnamon (for the cinnamon swirl)
Optional Frosting:
- 2 tablespoons Greek yogurt
- 1 teaspoon cream cheese, softened
- 1/2 teaspoon maple syrup or powdered sugar

Instructions

Step 1: In a microwave-safe mug (at least 12 ounces), combine the protein powder, oat or almond flour, baking powder, cinnamon, and salt. Mix these dry ingredients well.
Step 2: Add the egg, almond milk, maple syrup, and vanilla extract to the dry mixture. Stir thoroughly until the batter is smooth, making sure to scrape the sides of the mug.
Step 3: In a small separate bowl, mix the coconut oil or melted butter, brown sugar, and cinnamon until evenly combined to create the cinnamon swirl mixture.
Step 4: Spoon the cinnamon swirl mixture on top of the batter in the mug. Use a toothpick or knife to gently swirl it into the batter for that classic cinnamon roll effect.
Step 5: Microwave the mug cake on high for 60 to 90 seconds, checking until the center is just set. Be careful not to overcook as microwave power varies.
Step 6: For the optional frosting, blend Greek yogurt, softened cream cheese, and maple syrup or powdered sugar in a small bowl until smooth.
Step 7: Spread or drizzle the frosting over the warm mug cake and enjoy immediately.

Tips & Variations

Use almond or oat flour to make the recipe gluten-free.
Swap the protein powder for a flavor you enjoy, like chocolate or cinnamon spice, to customize the taste.
Try using honey instead of maple syrup for a different sweetness profile.
For a vegan version, try flax egg instead of the egg and plant-based yogurt for frosting, but note texture may vary.
If you prefer, add chopped nuts or raisins to the batter for extra texture and flavor.

Storage

This mug cake is best enjoyed fresh but can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently in the microwave for 15–20 seconds before serving. If you add frosting, you may want to add a fresh layer after reheating.

FAQs

Can I use other types of protein powder?

Yes, you can use any protein powder you prefer, such as whey, plant-based, or collagen. Keep in mind flavors vary and may slightly affect the taste and texture.

What if I don’t have oat or almond flour?

You can substitute with whole wheat flour or all-purpose flour if gluten is not a concern, but the texture might be a bit different. Adjust moisture slightly if needed.
