Looking for a sweet treat that satisfies and supports your fitness goals? This high-protein vanilla cake is your new go-to. Soft, subtly sweet, and packed with protein, it’s the perfect guilt-free snack for any time of day. Plus, it’s super easy to make—with a few smart ingredient swaps that keep it light, fluffy, and full of flavor. Trust me: this isn’t your average “healthy” cake. You’ll want to bake it again and again.
Separate the eggs and set the egg whites aside. I always use three bowls to prevent egg yolk from getting into the last egg. So crack the egg, pour the egg white into another bowl, and repeat with the rest.
Add all the other ingredients for the cake to a bowl or put them in the blender. Blend until smooth.
Beat the egg whites until stiff and fluffy. Do this in a grease-free bowl.
Fold the egg whites into the cake mixture with a spatula, trying to keep as much air in as possible.
I spray the silicone cupcake molds with a little fat and divide the batter between them. You can fill them quite high because they will rise a little, but not too much. Place the cupcake molds in a muffin tin.
Bake in the preheated oven for about 18 minutes or until the cakes are done and golden brown. Remove from the oven and leave to cool completely on a wire rack.
Mix the cream cheese with the erythritol and mix well. This can be done with a fork. Stir in the cinnamon and taste to see if you want to add more sweetener.
Transfer the mixture to a piping bag and pipe small swirls onto the cakes.
