In a medium bowl, stir together almond flour, brown sugar, espresso powder, and salt.
Pour in melted butter and vanilla extract and stir well to saturate until it becomes the texture of wet sand. Fold in the mini chocolate chips.
Use a cookie scoop to scoop a small amount of dough into your hand and roll together until it becomes a 1.5" ball. Place cookie balls on a plate lined with parchment paper. Repeat with the rest of the dough.
Chill dough balls in the fridge for about 1 hour or until firm.
Melt chocolate in a pan until smooth and transfer to a small and deep bowl.
Use a toothpick to pick up each cookie dough ball and dip in the melted chocolate until covered. Shake off the excess chocolate and place on parchment paper to harden.
With a spoon, use the remaining chocolate to drizzle over each cookie dough bite and sprinkle with flaky salt before the chocolate hardens.
