Preheat the oven to 350 degrees F and line a baking sheet with parchment paper.
Using a stand mixer or a hand held electric whisk, cream together butter and sugar in a large bowl.
1 cup granulated sugar, 1 cup butter
Add the egg and vanilla extract, and beat to combine.
2 tsp vanilla extract, 1 egg
In a separate bowl, whisk together flour, baking powder, baking soda, and salt.
2¼ cup gluten free all purpose flour, 1 tsp baking powder, 1/2 tsp baking soda, 1/2 tsp sea salt
Add the dry ingredients to the bowl of wet ingredients and beat on low until a dough forms. Divide the dough equally into 3 separate bowls (I like to use a food scale to divide evenly).
In the first bowl, add ground up freeze dried strawberries and food coloring (if using) and stir until pink and uniform.
1/2 cup freeze dried strawberries, OPTIONAL: 3-4 drops red food coloring
In the second bowl, add cocoa powder and stir to combine. Leave the 3rd bowl of dough as is.
3 tbsp cocoa powder
Scoop a tablespoon of each dough and combine and roll them in the palm of your hands until a ball is formed.
Roll the dough in a bowl of sugar, then place on prepared baking sheet. Make sure they are at least 2 inches apart (you may need to bake in 2 batches).
Bake for 10-12 minutes until the edges are golden.
Cool for 10-15 minutes, then transfer to a wire rack to cool completely. They'll be fragile but will set as they cool.
