Preheat the oven to 375 degrees Fahrenheit.

In a medium bowl, combine flour, Splenda, baking powder, and salt.

Cut cold butter into the dry ingredients using a pastry blender or fork until the mixture resembles coarse crumbs.

In a separate bowl, whisk the egg into the milk.

Create a well in the center of the dry ingredients.

Pour the wet mixture (egg and milk) into the well.

Mix with a fork until the ingredients are just combined and slightly sticky.

Spread the dough evenly into a greased round cake pan or square baking dish.

Bake for 15-20 minutes, or until golden brown and a toothpick inserted in the center comes out clean.

Serve warm with desired toppings such as fruit, jam, whipped cream, or chocolate sauce.
