Creating Pink Vanilla Cake Squares is a straightforward process if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan.
2. Mix Dry Ingredients: In a bowl, whisk together the flour, baking powder, and salt. Set aside.
3. Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and granulated sugar until light and fluffy.
4. Add Eggs and Vanilla: Beat in the eggs one at a time, then stir in the vanilla extract.
5. Combine Mixtures: Gradually add the dry ingredients to the butter mixture, alternating with milk. Mix until smooth.
6. Add Color: Stir in the pink food coloring until you achieve your desired shade of pink.
7. Pour Batter: Pour the batter into the prepared baking pan, spreading it evenly.
8. Bake: Place in the preheated oven and bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
9. Cool: Remove from the oven and allow the cake to cool in the pan for 30 minutes before transferring it to a wire rack to cool completely.
10. Prepare Frosting: In a bowl, beat the softened butter for the frosting. Gradually add the powdered sugar and mix until combined. Add milk and vanilla extract, and beat until the texture is smooth and fluffy. Add additional pink food coloring if desired.
11. Frost the Cake: Once the cake has completely cooled, spread the frosting evenly over the top.
