Ingredients
• (Makes 1 Cupcake)
• 1 large egg white (approx. 16 g), beaten to stiff peaks
• 2 tsp walnut oil (approx. 10.4 g)
• 1 tsp European-style butter (approx. 5 g), melted
• 1 heaping tsp coconut flour (approx. 4.2 g)
• 1/2 tsp calorie-free granulated sweetener (approx. 1.5 g)
• 1/8 tsp baking powder (approx. 0.2 g)
• 3–5 drops high-quality vanilla flavor
Instructions
1. Preheat your oven to 350°F (175°C). Place a single silicone cupcake liner on a small baking sheet.
2. In a clean, dry bowl, beat the egg white until stiff, glossy peaks form. This is the most crucial step for a light, airy texture.
3. In a separate small bowl, whisk together the coconut flour, sweetener, and baking powder to remove any lumps.
4. Gently fold the melted butter, walnut oil, and vanilla flavor into the beaten egg whites. Use a spatula and be careful not to deflate the mixture.
5. Sift the dry over the egg white mixture and fold again until just combined. Do not over-mix.
6. Carefully pour the batter into the prepared silicone liner and bake for approximately 15 minutes, or until the top is golden and a toothpick inserted into the center comes out clean.
7. Let cool slightly before frosting or enjoying as is.

Pro Tips
• For the fluffiest result, ensure your egg white is at room temperature before beating. This helps it achieve maximum volume.
• Use a gentle, figure-eight folding motion with a spatula to combine the . This prevents deflating the delicate egg white foam.
• Don’t have walnut oil? Melted coconut oil or a neutral avocado oil are excellent substitutes.
• For a richer flavor, try browning the butter before melting and adding it to the batter for a nutty, caramelized note.
FAQ
Q: Why is my single serving vanilla cupcake dense instead of fluffy
A: The key to a light and fluffy texture is the beaten egg white. Ensure you beat the room-temperature egg white to stiff, glossy peaks. When combining ingredients, use a gentle folding motion to avoid deflating the air you’ve incorporated, which is crucial for a fluffy keto cupcake.
Q: Can I use a different flour for this keto cupcake recipe
A: This recipe is specifically formulated for the high absorbency of coconut flour. Substituting it with another flour like almond flour would require changing the liquid and fat ratios and is not recommended for achieving the intended light texture.
Q: What can I substitute for walnut oil in this recipe
A: Yes, if you don’t have walnut oil, you can easily substitute it with an equal amount of melted coconut oil or a neutral-flavored oil like avocado oil. For a richer, nuttier flavor, you can also use browned butter.
Q: Can I make this cupcake in the microwave
A: While this recipe is designed for oven-baking to get a traditional cupcake texture, you could adapt it for the microwave. Place the batter in a microwave-safe mug and cook for 60-90 seconds. The result will be closer to a spongey mug cake.
