Crazy Whoopie Pie

Preheat oven to 350 F. Coat two 12-cavity whoopie pie pans with cooking spray. Set aside.

Finely chop frozen spinach using a large chopping knife. I find the spinach chops better frozen than at room temp. Microwave for a few seconds to defrost. Wrap in 3 to 4 layers of paper towels and squeeze dry. Set aside.

Add flour, cocoa powder, Stevia, sugar, salt, and baking soda into a medium bowl. Add spinach, separating the clumps as best as you can. Use a whisk to blend spinach into the flour mixture. Make 3 wells in the flour mixture using a spoon. Add oil into one, vinegar into the second, and vanilla into the third. Add water and whisk until blended.

Pour batter into each baking sheet cavity, filling each half way. Bake about 7 minutes or until a toothpick inserted in the center of one comes out with a few sticky crumbs. Remove from oven.

Allow to cool for a few minutes. Transfer to a cooling rack to cool completely. To assemble, spread a dollop of frosting on one cake. Top with a second. Repeat with the remaining cakes.
