01 - In a large mixing bowl, whisk together almond flour, coconut flour, powdered erythritol, and sea salt until thoroughly incorporated and no lumps remain.
02 - Add softened butter and vanilla extract to the dry mixture. Using a spatula or hand mixer, blend until a cohesive dough forms and all flour is absorbed.
03 - Pour in heavy cream one tablespoon at a time, mixing after each addition, until dough achieves desired texture. The dough should be pliable but not sticky.
04 - Gently fold sugar-free dark chocolate chips into the dough until evenly distributed throughout.
05 - Sample a small amount of dough and add additional sweetener if needed to achieve preferred sweetness level.
06 - Serve immediately for a softer texture or refrigerate for 15 minutes for firmer, scoopable dough. Store remaining portions in an airtight container in the refrigerator for up to 5 days.
