Follow these straightforward steps to create your Lemon Strawberry Jam Cake:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

2. Mix Dry Ingredients: In a bowl, whisk together the flour, baking powder, and a pinch of salt. Set aside.

3. Cream Butter and Sugar: In a large mixing bowl, cream the softened butter and granulated sugar until light and fluffy.

4. Add Eggs and Flavors: Beat in the eggs, vanilla extract, lemon zest, and lemon juice until well combined.

5. Combine Mixtures: Gradually add in the dry ingredients, alternating with the milk. Mix until just combined.

6. Pour Batter: Divide the batter evenly between the prepared cake pans.

7. Bake: Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean.

8. Cool the Cakes: Allow the cakes to cool in their pans for about 20-30 minutes before transferring them to wire racks to cool completely.

9. Spread the Jam: Once the cakes are completely cooled, place one layer on a serving platter. Spread a generous layer of strawberry jam over the top.

10. Stack and Dust: Place the second cake layer on top of the jam-covered layer. Dust the top with powdered sugar for an elegant finish before serving.
