1. Preheat the Oven:

• Preheat the oven to 180°C (350°F).
• Prepare a cake pan by greasing and dusting with flour or lining it with parchment paper.

2. Make the Cake Batter:

• In a large bowl, beat the eggs with a pinch of salt until frothy.
• Add the sugar and beat until light and fluffy.
• Stir in the vanilla flavor, seed oil, and milk. Mix well.
• Sift together the flour and baking powder. Gradually fold the dry ingredients into the wet mixture until smooth.

3. Prepare the Filling:

• In another bowl, whisk the egg with a pinch of salt until frothy.
• Add the fresh cheese, sugar, and vanilla flavor, whisking until smooth and creamy.

4. Assemble the Cake:

• Pour half the cake batter into the prepared pan and spread evenly.
• Spoon the cheese filling over the batter, spreading it evenly. Scatter blueberries on top.
• Pour the remaining cake batter over the filling, spreading gently to cover the blueberries.

5. Bake the Cake:

• Bake in the preheated oven for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
• Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

6. Serve:

• Slice the cake and serve with a dusting of powdered sugar, if desired. Pair with tea or coffee for an extra-special treat!
