First, prepare all of your ingredients. The cream cheese and eggs should be at room temperature, as this helps to create a uniform mixture.
Straight from the fridge?
If you forget to remove the cream cheese from the fridge in advance, cut it into cubes, place in a bowl and give it 15 seconds in the microwave. It should soften nicely without melting.
For eggs straight from the fridge, place them whole in a bowl. Run warm water from the tap over the eggs for a few minutes to help bring them closer to room temperature.
