Prepare blintzes according to directions.
In a medium-size bowl, beat together cream cheese, cottage cheese, softened butter, egg yolk, honey, and vanilla.
Place about 2 tablespoons cheese mixture on cooked side of each blintz.
Roll up, leaving ends open.
In a large skillet, melt butter.
Saute blintzes, seam-side down, until browned.
Turn, and continue cooking until all sides are browned.
