Preheat your oven to 350°F (175°C). Grease and line a 9x13-inch baking pan with parchment paper.

In a bowl, whisk together the flour, baking powder, and salt.

In a separate large bowl, beat the butter and sugar until light and fluffy.

Add eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

Gradually add the dry ingredients to the butter mixture, alternating with the milk. Mix until combined.

Pour the batter into the prepared pan and smooth the top.

Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.

Let the cake cool completely before slicing it into squares.

Beat the butter until creamy. Gradually add powdered sugar, mixing well.

Add the heavy cream and vanilla extract, then beat until fluffy.

Mix in pink food coloring until you achieve the desired shade.

Pipe or spread a generous layer of pink frosting over each cake square.

Decorate with sugar pearls in varying sizes and small heart-shaped sprinkles for charm.

Use a piping bag with a star tip to create swirls or patterns.

Arrange the squares neatly on a white serving platter.
