Step 1: Preheat the Oven

• Preheat your oven to 180ºC (350°F).
• Line a 20 cm (7.8 inches) cake pan with parchment paper. Set the pan aside.

Step 2: Prepare the Batter

Mix Wet Ingredients:

• In a large mixing bowl, crack two large eggs. If you're using a flaxseed egg, mix 1 tablespoon of flaxseed meal with 3 tablespoons of water and let it sit for a few minutes until it thickens.
• Add 1 cup of Greek yogurt to the bowl. Mix the egg and yogurt until the mixture is smooth and well combined.

Add Dry Ingredients:

• Add 1 cup of oat flour, 1 scoop of protein powder, 1/4 cup of cocoa powder, and 1 teaspoon of baking powder to the wet mixture.
• Add a pinch of salt to enhance the flavors.

Sweeten the Batter:

• Pour in 1/4 cup of maple syrup. Mix everything together until smooth.

Adjust Consistency:

• Gradually add milk to the mixture. Start with 60 ml (1/4 cup) and add up to 180 ml (3/4 cup) as needed. The amount of milk required will depend on the protein powder used. Mix until the batter is smooth and has a thick, pourable consistency.

Step 3: Bake the Cake

Transfer the Batter:

• Pour the prepared batter into the lined cake pan. Spread it evenly with a spatula.

Bake:

• Place the pan in the preheated oven and bake for 20 to 25 minutes.
• Check for doneness by inserting a toothpick into the center of the cake. If it comes out clean, the cake is ready.

Cool the Cake:

• Take the cake out of the oven and let it cool in the pan for about 10 minutes.
• Move the cake to a wire rack and let it cool completely to room temperature.

Step 4: Prepare the Chocolate Ganache

Melt the Chocolate:

• Put 1/2 cup of chocolate chips in a microwave-safe bowl.
• Microwave the chocolate in 15-second increments, stirring after each interval until the chocolate is fully melted and smooth. This should take about 45-60 seconds.

Mix with Milk:

• Once the chocolate is melted, add 2 tablespoons of almond milk (or any milk of your choice).
• Stir until the milk is fully incorporated and the ganache is smooth and glossy.

Step 5: Frost the Cake

Apply the Ganache:

• Once the cake is completely cool, pour the chocolate ganache over the top.
• Use a spatula to spread the ganache evenly over the surface of the cake.

Serve:

• Slice the cake into pieces and serve. Enjoy your healthy and delicious protein cake!
