This chocolate protein cake is one of the easiest and most indulgent protein powder recipes. It's moist, fluffy, and packs in 25 grams of protein per slice.
Preheat the oven to 180C/350F. Grease an 8-inch cake pan and set aside.
In a large mixing bowl, whisk together the dry ingredients. In a separate bowl, whisk together the maple syrup, eggs, Greek yogurt, and melted butter.
Slowly add the wet ingredients into the dry ingredients, then stir through the hot water until a smooth and thick batter remains.
Transfer the cake batter into the cake pan and bake the cake for 28-30 minutes, or until a toothpick comes out mostly clean.
Let the cake cool completely before slicing in half down the center.
Make the frosting by whisking together the Greek yogurt, powdered sugar, and chocolate protein powder. If the frosting is too thick, add a little extra powdered sugar.
Frost the base layer of the cake, add the top, and frost on top and around the sides.
