Hard Candy
Hard candy is a good way to feed bees without overly stimulating brood production, but it takes a more preparation.   It's usually not practical for beekeepers with a lot of hives.  Here are two recipes:

Microwave Candy Recipe
 (feeds 1 or 2 colonies)

1. In a one quart ( or larger) microwave dish, mix thoroughly one and a half cups granulated sugar and one-half cup light corn syrup ( 3:1 ratio).  No water.

2. Microwave on a high setting, stirring every few minutes, until the mixture is clear and bubbles become larger (thumbnail size), about 10 minutes. Bubbles should be large, but is stop immediately if the mixture starts to brown. A wooden spoon is very effective for stirring, as it can be left in the dish during microwave cooking. 

3. Pour into a mold made from cardboard or a container lined with paper to cool. The candy will become brittle, and can be slipped on top of frames or between in a hive, where the bees will consume it.

Stovetop Candy Recipe

1. Heat one pint (1/2 liter) of water to boiling in a large pot on stove.  

2. Stir in as much sugar as can be dissolved.  This will be about 5 pounds (2 Kg).  More sugar is better.   

3. Boil, uncovered, stirring almost constantly until the mixture reaches 234 degrees F.  It takes awhile.

4. Pour into molds made of cardboard or a container lined with waxed paper or butcher paper.   The candy will harden as it cools.

Basically, any peanut brittle recipe can be adapted to make bee candy.
