Ingredients:
For the Cake:
- 1 1/2 cups almond flour (240g)
- 1/4 cup coconut flour (30g)
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1/2 cup unsweetened Greek yogurt (120g)
- 3 large eggs
- 1/2 cup melted unsalted butter (113g)
- 1/4 cup erythritol (or your preferred keto-friendly sweetener equivalent to 1/4 cup sugar)
- 2 tablespoons lemon zest (from about 2 lemons)
- 1/4 cup freshly squeezed lemon juice (about 1 lemon)
- 1 teaspoon vanilla extract
For the Lemon Glaze:
- 1/4 cup powdered erythritol (for the glaze)
- 2 tablespoons lemon juice (freshly squeezed)
- 1 teaspoon lemon zest (optional, for extra flavor)

Instructions:
- Preheat the Oven
Start by preheating your oven to 350°F (175°C). Grease an 8-inch round cake pan or line it with parchment paper to ensure easy removal of the cake later. - Prepare Dry Ingredients
In a large mixing bowl, combine the almond flour, coconut flour, baking powder, and salt. Stir them together with a whisk to ensure that the baking powder is evenly distributed throughout the dry ingredients. - Mix Wet Ingredients
In a separate bowl, whisk together the Greek yogurt, eggs, melted butter, erythritol, lemon zest, lemon juice, and vanilla extract. Whisk until smooth and creamy, making sure the butter has cooled slightly before adding it to the mixture to avoid curdling the eggs. - Combine Wet and Dry Ingredients
Gradually add the wet ingredients to the dry ingredients, stirring gently to combine. Be careful not to overmix, as that can cause the cake to be dense. You’re looking for a thick, smooth batter. - Pour and Bake
Pour the batter into the prepared cake pan and spread it out evenly. Smooth the top with a spatula. Bake in the preheated oven for 25-30 minutes or until a toothpick inserted into the center comes out clean. - Cool the Cake
Once baked, remove the cake from the oven and allow it to cool in the pan for 10-15 minutes. Then, transfer the cake to a wire rack to cool completely. The cooling process is important because it ensures the cake sets and slices beautifully. - Prepare the Lemon Glaze
While the cake cools, prepare the glaze by whisking together the powdered erythritol and lemon juice in a small bowl. If you prefer a more intense lemon flavor, add a teaspoon of extra lemon zest to the glaze. - Glaze the Cake
Once the cake has completely cooled, drizzle the lemon glaze over the top. You can also spread it evenly with a spatula. If desired, garnish with a few extra lemon zest pieces for a touch of color and flavor. - Serve and Enjoy
Slice the cake into 8-10 pieces, and enjoy a slice of this tangy, moist, and delicious keto lemon yogurt cake. It pairs beautifully with a hot cup of tea or coffee.

- Experiment with Sweeteners: If you prefer a different sweetener, feel free to substitute the erythritol with your preferred keto-friendly sweetener like monk fruit or stevia, but be sure to adjust the quantity to match the sweetness level of the substitute.
