Line a 9x5” loaf pan with parchment paper. (See the photos in the blog post above.)
In a small bowl, whisk together the coconut flour, soy protein powder, and salt. In a separate bowl, whisk together the coconut oil, milk, and vanilla. Stir in the Truvia and SweetLeaf until fully incorporated. Add in the flour mixture, stirring until fully incorporated. Fold in 1½ tablespoons of chocolate chips.
Pour the crumbly dough into the prepared pan, and gently press it across the bottom using a spatula. Gently press the remaining chocolate chips into the top. Chill for at least 2 hours before slicing into bars. Store in the refrigerator in an airtight container until ready to eat.
