Preheat your oven to 350°F and grease a large rectangular baking pan.

In a saucepan, melt one cup of butter and stir in two cups of sugar until well combined.

Remove from heat and let cool slightly, then mix in four large eggs and one teaspoon of vanilla extract.

In a separate bowl, combine one cup of all-purpose flour, one cup of cocoa powder, half a teaspoon of baking powder, and half a teaspoon of salt.

Gradually add the dry ingredients to the wet ingredients until just combined, ensuring a smooth and luscious batter.

Pour the batter into the prepared baking pan and spread evenly.

Bake for twenty to twenty-five minutes or until a toothpick comes out clean, watching them puff up to perfection.

Let cool completely before decorating to achieve a pretty finish.

Use white icing to create football stitches on top and green icing for the field effect.

Cut into squares and serve at your football party, ensuring every bite is enjoyed.
