(There are many variations on the internet, but I bet these are the cheapest, because I use raisins.)
2 cups raisins (about 12 oz)
1 1/3 cup shredded coconut or finely chopped nuts
(about 5 oz coconut flakes)
2 tsp cinnamon
2 tsp vanilla
In food processor, shred coconut flakes or chop nuts. Pour into another container.
Process raisins, cinnamon, and vanilla until raisins are chopped tiny and want to stick together in a big clump. Break up the clump and add coconut or nuts. Process until thoroughly mixed, stopping as needed to break up the clump and scrape the sides.
Line a 9×5 bread pan with wax paper, allowing extra to cover the top. Press the clump into the pan, using the edges of wax paper.
Use the wax paper to lift the whole bar out of the pan. Turn it upside down onto plastic wrap and carefully pull off the paper. Wrap in plastic wrap and refrigerate several hours. Unwrap and cut in bars.
Note: I haven’t found a way to make these without both wax paper and plastic wrap. If you press it directly into the pan, good luck getting the bars out. If you refrigerate it in the wax paper, it sticks and you have wax all over the bars.
(I figured this out from several recipes on the internet, but this version is from my own experimentation.)
