A couple of years ago, Jenny got me some ice cream sandwich molds from Williams Sonoma. Yesterday, I used them for the first time.
Step 1 - Super fudgy but thin brownies for the outsides, cut into shapes.

Step 2 - Assemble - I started assembling by hand - the results were authentic, but not quite perfect.

Step 3 - Then J pointed out that the molds are supposed to be used to assemble, too. I tried and, voila - the cows ended up quite professional looking.

Note: I inserted a strawberry in the middle of each - a nice surprise I thought. Hmmm. They freeze REALLY hard - caution when eating! Now I know.
Now I have a bunch of small treats in the freezer - awesome way to start the summer.
