I grew up on the Texas-Mexico border in south Texas.

We would often cross the border into Mexico to do shopping. My parents
would always buy this candy. They called it "goat milk candy".

It was a cylinder of candy, about 2 inches diameter, maybe 4-5 inches
long. It was a very light tan in color, and was soft and creamy. Very
sweet. You didn't suck on this candy, a nibble size piece would pretty
much melt quickly in your mouth.

Anyone know what this candy would be called?

Perhaps this is what you are looking for. I have not tried the recipe
yet, but is sounds close to what you are describing.

Cajeta (Mexican Caramel Candy)

3 quarts goat's milk
2 tablespoons Cornstarch
3 cups sugar
1/4 tsp baking soda

Dissolve baking soda and cornstarch into 1 cup of milk. Stir well to
dissolve breaking up lumps. Add the rest of the goats milk and add
sugar. Bring to a boil stirring constantly while cooking. Cook until
ixture is think and looks like caramel sauce. Pour into jars,cool and
refrigerate. This makes a great topping for ice cream and is also a
delicious apple dip.
