This isn't about beer, but it is about doing things for yourself. A few weeks ago, I wanted some chocolate milk, but we were out of syrup, and my wife was out with the car. I found out you can make your own chocolate syrup with cocoa powder. This is all it takes.
1/2 cup cocoa powder
1/2 cup(rounded) sugar
1/2 cup water
2 dashes vanilla extract
Mix the cocoa and sugar well. Add the water and heat over medium-low heat, stirring constantly, until a thin syrup forms. Continue to heat until it boils and begins to thicken. Take off heat and add vanilla. Allow to cool, and pour into bottle of your choice.
Once I realized how easy this is, and how good it tastes, I decided I'm never buying chocolate syrup again.
