Line an 8-inch (20 cm) square baking dish with parchment paper to hang over the edges.
2. Step
Make the crust: in a medium bowl, combine the almond flour, coconut oil, honey, cinnamon, and salt. Mix with a spatula until smooth.
3. Step
Transfer the crust to the baking dish. Use a spatula to smooth the crust into a thin, even layer covering the bottom of the pan. Set aside.
4. Step
Make the filling: open the cans of coconut milk and use a spoon to scoop the thick cream at the top of the can into a medium bowl. Set aside the remaining liquid for another use, such as in smoothies, soups, or sauces.
5. Step
Beat the coconut cream with a hand mixer until very fluffy, about 5 minutes.
6. Step
Add the lime juice and honey. Continue to beat until smooth and fluffy, about 2 minutes.
7. Step
Pour the filling over the crust and use a spatula to smooth out the top.
8. Step
Top with the lime zest.
9. Step
Freeze for at least 2 hours, until the filling has set.
10. Step
Grab the parchment on both sides and lift the frozen bar from the baking dish. You may need to use a knife to release the edges or turn the dish upside down on a cutting board and tap on the bottom to release the block.
11. Step
Quickly cut the block into 16 2-inch (5-cm) square bars.
