Here's a delish-sounding recipe for "Red Eye Rice Treats" — caffeinated vegan rice-krispie squares that give you the pep you need to make it through the day:
6 cups puffed brown rice [any puffed rice will do, really]
1 cup peanut butter [I scored a few jars of White Chocolate Peanut Butter & Co for cheap, so I used up the rest of mine: creamy might be your best bet, no matter what]
1 cup brown sugar corn syrup [or brown rice syrup, organic light corn syrup…if you want maple syrup, I'd recommend going the half/half way by mixing it up with granulated sugar or rather fine other sugar]
1/2 t pure vanilla extract
1 t instant coffee crystals, crushed into a fine powder with the back of a spoon [up this a bit if you want a stronger coffee flavor, 2 t maximum to avoid overwhelming the other flavors]
1/3 cup carob powder [if you're a hater, I'm sure cocoa powder would be a fine substitution here]
You could probably substitute agave syrup for the corn syrup (blending it with something?) to get a super-low-GI version.
