Easy Blueberry White Chocolate Protein Mug Cake

Table of Contents

Protein powder is such a versatile ingredient. Not only can it be used in protein shakes, but it also lends well to baking and sweets. It adds sweetness, texture, and a healthy boost of protein in anything you put it in. A nicely flavored protein powder is a great pantry staple to keep on hand.

A favorite protein powder recipe is this Easy Blueberry White Chocolate Protein Mug Cake. Vanilla protein powder is used to create a delicate cake texture. Fresh juicy blueberries and creamy white chocolate chips are suspended throughout the cinnamon-scented cake. This is the perfect late-night sweet snack!

Mug cakes are so easy and are made right in the microwave. No oven required! Simply mix all the cake ingredients in the mug and cook for 2 minutes on high heat. The blueberries will burst in the cake and the white chocolate will melt into rich chocolate puddles.

The cake itself rises in the microwave thanks to the addition of baking powder. Natural maple syrup sweetens the cake instead of pure sugar. Instead of using flour, vanilla protein powder, applesauce, and egg bind together to bake this cake. The texture is like that of a slice of homemade cake.

The cake batter stands out because it has multiple levels of flavor. Ground cinnamon adds warmth to the cake without overpowering the fruit or chocolate. Vanilla extract and vanilla protein powder add the classic flavors that you associate with cake.

Use any flavor of protein powder that you have or like. Vanilla is a very mild base flavor, but you could use cinnamon roll flavor since there is already cinnamon in the cake. Birthday cake-flavored protein powder also exists, so you could make a cake-flavored mug cake! Any flavor of protein powder would work in this mug cake.

If you like other fruit combinations along with white chocolate, feel free to swap out the blueberries! This protein mug cake would be delectable with fresh raspberries, bananas, strawberries, or blackberries. You could also use milk or dark chocolate chips if you prefer.

Once the cake is hot out of the microwave, it is perfectly delicious to eat it as-is. Or, if you want to make this cake over-the-top, you could serve with some whipped cream or ice cream on top. A big scoop of vanilla bean or butter pecan ice cream over the warm mug cake is truly heavenly. Or, use your favorite ice cream flavor!

Make this decadent mug cake on a late night when you need a sweet treat. It comes together in only 5 minutes, which is appealing for someone who just wants to quickly eat cake in their pajamas. Easy Blueberry White Chocolate Protein Mug Cake is the perfect reason to stay up late and snack on some cake!

Ready a large coffee mug. Rub the butter around the inside of the cup to prevent the cake from sticking.


In the greased mug, combine the applesauce, maple syrup, and cinnamon. Mix well. Add the protein powder and baking powder. Finally, mix in the egg, vanilla, and sea salt and combine into a very well-mixed batter. Break up any lumps from the protein powder for even cooking.


Fold in the white chocolate chips and fresh blueberries. They will sink slightly when they cook.


Microwave on high for 2 minutes. If the cake is not fully cooked, heat for another 30 seconds until the cake is done in the middle.


Remove the mug from the microwave. Allow the cake to cool slightly for 1-2 minutes. Serve with whipped topping or your favorite flavor of ice cream, if desired.
