Tia Maria Sour Cream Dip for Fruit

I first tried this years ago when a friend passed on the recipe. I whipped the ingredients together until thick and loved the result but later found my friend just stirred hers so her dip was quite liquidy. I actually prefer it whipped but either way guests enjoy it. I have also used Godiva or Mozart Liqueur (chocolate) depending on what I have available. I made this yesterday with Mozart Liqueur for JanS - she requested I submit the recipe.
