Preheat the oven to 350°F and line a baking sheet with parchment paper.
In a large bowl, mix together the almond flour, oats, baking soda, cinnamon, and salt until evenly distributed.
In a separate bowl, whisk the egg, honey, melted butter, and vanilla extract until smooth.
Pour the wet ingredients into the dry ingredients and stir until just combined. The dough will be slightly sticky.
Use a cookie scoop to form balls of dough. Place them on your prepared baking sheet and gently press each ball to slightly flatten into cookie shapes.
Bake in the preheated oven for about 10-12 minutes, or until the edges are lightly golden.
Remove the cookies from the oven and let them cool on the baking sheet for a few minutes before transferring them to a cooling rack to cool completely.
Once the cookies are fully cooled, spread or pipe a generous layer of cream cheese frosting on the flat side of one cookie. Top with another cookie to form a sandwich. Repeat with the remaining cookies and frosting.
