The Art Behind Perfect Swirls
Getting those gorgeous swirls depends on getting temperatures just right. Your chocolate dough can't be too soft or too firm. When you add warm peanut butter to cool chocolate dough, you get that awesome marble look without the colors mixing too much. It's kind of like when you're painting - you want clear, separate streaks that flow together without turning into a brown mess.
Keeping Them Fresh
Put them in sealed containers with wax paper between each layer. They'll stay good for 5 days on your counter or you can freeze them for up to 3 months.
