Preheat oven to 350 degrees Fahrenheit.
In a large mixing bowl, whisk together softened vegan butter, sugar, brown sugar, orange juice concentrate, orange zest, water, vanilla, and salt.
Once liquid ingredients are thoroughly mixed, add flour, baking powder, and sliced almonds to mixing bowl, and stir together.
Form heaping tablespoon sized mounds of dough, and place them on a lined cookie sheet, about 12 cookies/sheet. (I line my cookie sheets with silicone liners, but oiled parchment paper would work too.)
Bake at 350 degrees Fahrenheit for 8-10 minutes, or until cookies are just starting to turn golden brown on the edges.
Allow to cool on cookie sheet for a minute or two before transferring them to cooling rack.
