Place toasted almonds, oats, and vanilla wafers in the bowl of a food processor, and process well - until fine crumbs.
Remove ¾ cup of the crumb mixture and set aside.
Add almond paste and apricots to the remaining almond, oat mixture in the food processor.
Pulse until mixture is well combined, scraping down the sides of the bowl several times, and then process mixture until smooth.
"Batter" will be sticky, but should not be too wet or crumbly.
If apricot mixture seems too wet, add additional nut-oat crumbs, 1 Tbs at a time. If mixture seems too crumbly, add water 1 teaspoon at a time.
Use a teaspoon to scoop out batter and roll into 1-inch truffle sized balls.
Roll each ball in the remaining nut-oat mixture.
Store Apricot Almond Truffles in the refrigerator.
