Start by preheating your oven to 350°F (175°C). Line an 8-inch round cake pan with parchment paper and grease the sides. This will help the cake release without a fuss. In a mixing bowl, cream the softened butter and granulated sugar together until it's light and fluffy. This can take about 3-5 minutes. Add the eggs one at a time, ensuring each is well incorporated. You want that airy texture. Next, stir in the vanilla extract and milk, blending these ingredients smoothly. In a separate bowl, whisk together the flour, baking powder, lemon zest, and salt. Gradually mix the dry ingredients into the wet ingredients until just combined. Don’t overmix. You’re looking for a blend that feels light and fluffy. Pour the batter into the prepared cake pan and spread it evenly. Bake for 25-30 minutes, or until a toothpick comes out clean from the center. The aroma wafting through your kitchen during this time will be heavenly. Let the cake cool in the pan for about 10 minutes before transferring it to a wire rack. Allow it to cool completely.

While the cake cools, let’s work on the strawberry filling. In a medium saucepan, combine the chopped strawberries and granulated sugar. Cook them over medium heat for about 5 minutes until the strawberries start to release their juices. Add the fresh lemon juice and stir it in. This tanginess takes the strawberry flavor up a notch. In a small bowl, whisk together the cornstarch with a couple of tablespoons of the strawberry mixture. Once it's smooth, add it back into the saucepan. Cook the mixture until it thickens slightly, about 2-3 minutes. Remove it from the heat and let it cool.

Take a large mixing bowl and add the cold heavy whipping cream. Using an electric mixer, whip it on medium speed until soft peaks form. Gradually add the powdered sugar and vanilla extract, and continue whisking until stiff peaks form. You want that cream to hold its shape beautifully.

Once the cake is cool, slice it in half horizontally. Place one layer on a serving platter. Spread the strawberry filling evenly over that layer, and then carefully add a nice layer of strawberry ice cream on top. Gently place the second layer of cake on top. Now, it’s time for that lovely whipped cream to shine. Spread it generously over the top and sides of the cake. For an extra touch, decorate with pink food coloring or sliced strawberries. Your cake should now look like a decadent treat, ready to impress!
