Preheat your oven to 350°F (175°C). Line an 8x8-inch baking dish with parchment paper, ensuring some overhangs the sides—this makes lifting the bars out super simple!
In a medium bowl, whisk together the coconut flour, sesame or almond flour, 1/4 cup of the Monk Fruit Allulose sweetener, and the sea salt. Next, add the room temperature coconut oil (or melted butter). Use two butter knives or a food processor to cut in the oil until the mixture resembles coarse crumbs.
Press this crumbly crust mixture firmly and evenly into the bottom of your prepared baking dish. Pop it into the preheated oven and bake for just 10 minutes, or until it looks lightly golden and smells wonderful.
While the crust is baking, grab another bowl. Whisk together the eggs, fresh lime juice, vibrant lime zest, the remaining 1 cup of Monk Fruit Allulose sweetener, and the coconut stevia until everything is smooth and perfectly blended.
Once the crust is out of the oven, carefully pour the bright lime-egg mixture over the warm base. Evenly sprinkle the unsweetened shredded coconut flakes over the top for an extra layer of flavor and texture. Return the dish to the oven and bake for another 12-15 minutes, or until the center of the bars is set (it shouldn't jiggle too much when gently shaken).
Let the bars cool in the dish for about 10 minutes. Then, use the parchment paper overhang to carefully lift the entire slab onto a cutting board. Slice into 16 delicious bars. While you can enjoy them warm, they taste incredibly refreshing and have the best texture when chilled in the refrigerator before serving. Store any leftover bars in an airtight container in the fridge for up to 5 days, or freeze for a month!
