They're pretty much all the same difficulty: boil water, add extract, add hops, chill, pitch, wait 2 weeks, prime and bottle, wait 3 more weeks, drink.
If you're looking for an easy recipe, try 6 gallons of water, 6-8 pounds of amber extract, and 2-4 ounces of Cascade hops. Add half the hops after adding the extract and the boil returns (beware of boil-overs), and the other half of the hops after the wort has boiled for 45 minutes. Boil 15 more minutes, remove from heat and chill. Transfer to sanitized fermenter, add a packet of Nottingham Ale Yeast, seal the fermenter and put in the airlock. Leave in a cool, dark area. After 2 weeks your beer should be fermented. Add priming solution (3/4 c of corn sugar boiled in water for 15 minutes and chilled) to the fermenter, mix slowly, and transfer it to bottles. Wait 3 weeks, chill some bottles, and enjoy.
