Here's one that showcases sandwiches from around the world.
Are you hungry yet?
If you want something richer and faster, here's a recipe for a chocolate peanut butter mug cake. I made one tonight and it was pretty good. (Sorry, there's no music).
If you'd like to see the printable recipe, here it is. Enjoy!
Or, for a simple peanut butter mug cake (no chocolate), try this recipe. I haven't tried this one myself yet, so...I hope it's as good as it sounds.
Note: this is not the image that was with the recipe, but it was as close as I could get, given that I haven't tried the cake yet. Here's the source for the image.
Have a great day!
