The sweet tartness of key lime is captured in our whoopie pies made with Betty Crocker SuperMoist Yellow cake, graham crackers and key lime pie yogurt.
SAVE ON THIS RECIPE!
You can make the filling ahead and store it in the refrigerator until you’re ready to assemble the whoopie pies.
Fresh lime juice can be substituted for bottled; you’ll need to juice about 3 medium limes to get 6 tablespoons.
