Preheat oven to 350°F and line a sheet pan with parchment paper.
In a large bowl, whisk together butter, Splenda Sweetener, lemon zest, tea leaves, and salt. Add almond flour and knead until the mixture holds together in a dough.
Roll dough ½”-thick and cut cookies with a sharp knife or cookie cutter. Place cookies on a prepared baking sheet and prick the surface of each cookie with a fork.
Bake for 10 minutes or until golden-brown at the edges.
Cool on baking sheet for 5 minutes before transferring to a wire rack to cool completely.
