Swapping standard wheat flour for coconut flour alters the moisture balance entirely because coconut fiber absorbs liquid at a drastically higher rate. Without enough fat and eggs to hydrate it, the dough turns crumbly and fractures under pressure. Softening the butter and cream cheese thoroughly before mixing prevents lumps and creates a cohesive emulsion that holds the flour in suspension. Cream the dairy and erythritol thoroughly with a hand mixer at medium speed until pale and fluffy before adding the eggs. Coconut flour lacks gluten, meaning structure relies entirely on the coagulating proteins in the two eggs and the dairy fats. Roll the dough into uniform balls and press gently with a thumb to form indentation wells without splitting the edges. Bake at 325 degrees Fahrenheit for 15 minutes until the bottoms turn light golden brown. Cool the batch completely on a parchment-lined sheet to let the crumb set fully. Stored in an airtight container at room temperature, these cookies maintain their texture for up to three days, though the centers soften slightly by day two as moisture equilibrates.
