To make these bites, start by preparing the wet ingredients. Add the melted coconut oil, maple syrup, vanilla extract, and lemon juice to a small bowl, and whisk until they're fully combined.
Next, in a separate bowl, combine the dry ingredients: the almond flour, coconut flour, macadamia nuts, sea salt, and collagen peptides (if using).
Then, pour the wet ingredients into the dry ingredients and mix to fully combine.
Using your hands or a cookie scoop, scoop the dough into 12 even-sized balls. Line a baking sheet with parchment paper, then place each ball onto the parchment paper.
Next, prepare the icing. Add the powdered sugar, water, and lemon juice to a small bowl, and whisk to fully combine.
Then, spoon a little bit of the icing on top of each of the lemon bites.
Transfer the baking sheet to the refrigerator and allow the bites to set for 20-30 minutes.
Once they're done, remove from the fridge and enjoy! Store any leftovers back in the fridge, for up to one week.
