Preheat oven to 350 F.

In a large bowl or bowl of a stand mixer, combine butter, cream cheese, Swerve Confectioners, and Swerve Brown. When adding the Swerve Brown, sprinkle it on top of the other ingredients to make sure it evenly distributes when mixing.

Mix on medium-high for 5-6 minutes until fluffy.

Then, add one egg and mix it in on low. Add the second egg and do the same.

Add heavy whipping cream and vanilla extract, scrape down the sides of the bowl, and mix on low until well combined.

In a small bowl, thoroughly combine the coconut flour, cinnamon, cream of tartar, baking soda, salt, oat fiber (if using), and gelatin (if using). Add the dry ingredients to the wet and mix in on low for 30 seconds until combined.

Lightly spray the bottom of a casserole dish (I used 7x11”) with non-stick cooking spray, then evenly spread the batter into the dish.

Immediately before baking, mix equal amounts of Swerve Confectioners and cinnamon in a bowl, then dust the top of your cookie bars with as much as you would like.

Place casserole dish in the oven and bake for 15-20 minutes (highly dependent on your oven), until the edges begin to lightly brown. Do NOT overbake! The middle of the casserole will still be relatively soft/wet, but an inserted toothpick should come out mostly clean. The cookie bars will firm up as they cool.

Cut into 10 even pieces and serve.
