Ingredients

1 cup (220 g) Greek yogurt 5% fat or higher recommended
1 large egg
⅓ cup (30 g) cornstarch
⅓ cup (30 g) protein powder vanilla whey (replace with 2 tbsp cornstarch)
3 to 4 tbsp (60 ml) maple syrup or honey
3 tbsp freshly squeezed lemon juice from ½ lemon
1 tsp vanilla extract

Healthy Frosting

¼ cup (60 g) Greek yogurt
2 tbsp cream cheese low fat or full fat
1 to 2 tbsp maple syrup to taste
½ tsp vanilla extract

Instructions

Preheat the oven to 350°F (180°C) and line a 6-inch (15 cm) baking pan with parchment paper or grease it with oil.
In a large bowl, whisk together Greek yogurt, egg, maple syrup, lemon juice and vanilla extract until smooth.
Sift in the cornstarch and protein powder, then fold gently until fully combined; there should be no lumps left in the batter.
Pour the batter into the prepared pan and bake for about 30 minutes, or until the top is golden and a toothpick inserted into the center comes out clean.
Let cool for at least 15 minutes before frosting and serving.

Healthy Frosting

Add all ingredients to a bowl and mix until combined, adjusting sweetness to taste.
Using a spatula or spoon, gently spread the frosting on top of the lemon loaf, once it has cooled.

Notes

Storage directions

To store. After frosting, keep leftovers in an airtight container in the fridge for up to 3 days. The flavors deepen as it chills, so it tastes even better the next day.
To freeze. For a longer storage you can also freeze it, preferably before adding the icing. To freeze, wrap individual slices in plastic wrap, place them in a freezer-safe bag and store in the freezer for up to 3 months. When ready to enjoy, thaw at room temperature or warm it up in the oven.
