My Favortie Brands to Use in this Recipe:
- Wholesome Organic Powdered Confectioners Sugar: Wholesome powdered sugar is made from organic cane sugar, meaning it’s grown without synthetic pesticides, herbicides, or harmful chemicals. It is certified Non-GMO, ensuring that no genetically modified ingredients are used and free from artificial preservatives, colors, and flavors. Unlike many conventional powdered sugars that use cornstarch as an anti-caking agent, Wholesome uses organic tapioca starch. Wholesome Organic Powdered Confectioners Sugar isn’t just a sweetener—it’s a commitment to healthier eating, sustainable farming, and ethical practices. By choosing Wholesome, you’re opting for a product that’s better for your health, better for the environment, and better for the communities that produce it.
- Mapehill Organic 100% Grass-Fed Greek Yogurt: made from high-quality organic milk sourced from grass-fed cows, ensuring higher levels of beneficial omega-3s and CLA (conjugated linoleic acid) for heart and brain health. Unlike conventional yogurts, it’s free from artificial additives, hormones, and GMOs, making it a cleaner, more nourishing option. Its rich, creamy texture and probiotic content support gut health and digestion while providing a high-protein, nutrient-dense snack.
- A High Quality Protein Powder Brand: When choosing a protein powder, it’s important to avoid conventional options that contain artificial sweeteners like sucralose and aspartame, which can disrupt gut health and cause inflammation. Many also contain fillers, gums, and additives that can lead to bloating and digestive discomfort. Conventional protein powders may be sourced from low-quality, factory-farmed dairy with added hormones and antibiotics, or from heavily processed plant proteins treated with chemical solvents like hexane. Additionally, some contain heavy metals, pesticide residues, and GMOs, making them a less-than-ideal choice for long-term health. Opting for clean, organic, and minimally processed protein powders ensures better digestion, absorption, and overall wellness.


Chocolate Protein Cake
Ingredients
For the Cake:
- 1 Egg
- 1/2 cup Chocolate Protein Powder
- 1/2 cup Organic Pasture Raised Greek Yogurt
- 1/2 cup Oat Flour
- 1/4 cup Cocoa Powder
- 3/4 tsp Baking Powder
- 1/4 to 3/4 cup Milk: the quantity of milk depends on the type of protein powder you use. Casein and vegan protein powder will require more milk (about 180 ml or 3/4 cup) than whey (about 60 ml or 1/4 cup). Start with little and add as much milk as you need to get a smooth batter.
For the Vanilla Icing:
- 1 cup Confectioners’ sugar
- 45 ml Milk
Instructions
- Preheat your oven to 175°C (350°F). Line a 20 cm (7.8-inch) cake mold with parchment paper or lightly grease it
- In a mixing bowl, whisk together the chocolate protein powder, oat flour, cocoa powder, and baking powder.
- Crack the egg into the dry mixture, followed by the Greek yogurt. Stir to combine.
- Slowly add the milk, a little at a time, until you get a smooth batter. The exact amount will depend on your protein powder.
- Pour the batter into the prepared cake mold, smoothing the top. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
- Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool fully before icing.
- Whisk together the confectioners’ sugar and milk until smooth. If too thick, add a tiny bit more milk. If too thin, add more sugar.
- Drizzle the icing over the cooled cake. Slice and enjoy!
