Heat the olive oil in a large pan and sauté the onions and garlic. Cook on medium to low heat until they are caramelised, about 30 minutes. Allow to cool to room temperature.
Place the onions, cream cheese, sour cream and lemon in a food processor and pulse to combine. Adjust the seasoning to taste. Stir in the chives.
Chill until needed. Spoon onto the oatcakes to serve.
