Line an 8 x 8” baking dish with parchment paper then set aside.
In a large bowl, add the oats, coconut, almonds, chia seeds and lemon zest. Toss to combine.
In a small saucepan over medium-low heat, melt the honey and almond butter together. Stir until combined then remove from heat and immediately stir in the vanilla extract and lemon zest.
Pour the honey and almond butter mixture into the large bowl and stir everything until well-combined.
Quickly transfer the mixture to the lined baking dish and then use your hands (with a piece of parchment paper underneath) or a spatula to firmly press out to the sides. If you have a small pastry roller, that will help to flatten the top for perfectly shaped bars but it’s not necessary.
Place the baking dish in the refrigerator and chill for at least 2 hours (ideally up to 4 hours), until firm. Use parchment paper to lift it out of the baking dish then slice into 12 separate bars. Store in the refrigerator in a sealed container with parchment paper in between the bars to keep from sticking. Refrigerate for up to 1 week.
