Preheat the oven to 400 degrees.
Put the flour, cocoa powder, baking powder, and salt in a bowl and whisk until well combined.
⅔ cup 53g unsweetened cocoa powder, 1 teaspoon baking powder, 1 teaspoon salt, 2 Cups 240g white whole wheat flour (original just called for "flour")
In another bowl, beat the butter, sugar and vanilla until fluffy. Once fluffy, beat in the egg.
10 tablespoon softened butter, 1 cup organic coconut palm sugar, ½ teaspoon vanilla, 1 egg, ½ teaspoon vanilla
On low speed, beat in the flour in 3 batches alternating with the almond milk until just combined.
1 cup unsweetened almond milk
Spray non-stick cookie sheets with non-stick cooking spray. Scoop 18 mounds of the batter on the sheets about 2 inches apart. This is where we went wrong and made ours about double the size we should have.
Shape and smooth the mounds of batter with wet fingers.
Refrigerate for a few minutes to set (original said 30 minutes -- we waited 10, tops) and then bake for 10-12 minutes until firm.
Cool for 5 minutes on the sheets and then remove and let cool completely before adding the filling.
While the cookies are cooling, beat one stick of butter until fluffy then gradually beat in the powdered sugar ¼ cup at a time. Add the milk about halfway through.
1 stick of butter, 1 tablespoon almond milk, 1 ½ cups powdered sugar
