Begin by heating your oven to 350°F (175°C). This ensures an even baking process. Prepare an 8-inch round cake pan by either greasing and flouring it or lining it with parchment paper for easy removal.

In a medium bowl, whisk together the flour, baking powder, and salt. This step helps distribute the leavening agents evenly, which prevents any dense areas in the cake.

In a large bowl, beat the softened butter and sugar until the mixture becomes light and fluffy. This process incorporates air into the batter, aiding in the cake’s rise. Add the eggs one at a time, beating well after each addition. Next, mix in the vanilla extract to enhance the flavor.

Slowly incorporate the dry ingredients into the butter mixture, alternating with the milk. Start and end with the dry ingredients. This technique helps create a smooth batter without lumps. Be cautious not to overmix—combine just until everything is blended.

Gently fold the sliced strawberries into the batter using a spatula. Aim to distribute the strawberries evenly without breaking them down too much, so each slice of cake is studded with fruit.

Pour the batter into your prepared pan and smooth the surface with a spatula. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

While the cake is cooling, make the frosting. Beat the softened butter in a medium bowl until it becomes creamy. Gradually add the powdered sugar, mixing well between additions. Stir in the pureed strawberries and vanilla extract. Continue to beat until the frosting is smooth and airy.

Once the cake is fully cooled, spread the strawberry frosting evenly over the top and sides. Use an offset spatula for a smooth finish or to create decorative patterns. You can also garnish with additional fresh strawberries, either whole or sliced.

Cut the cake into slices and serve. This strawberry cake is delightful on its own but also pairs beautifully with a scoop of vanilla ice cream or a dollop of whipped cream. Enjoy every delicious bite!
