Line an 8-inch square baking pan with wax paper, parchment or greased foil. Set aside for later.
Bring a small skillet to medium heat. Add coconut. Stir until lightly browned and fragrant, about 3-5 minutes. Remove from heat and pour into a large mixing bowl.
Add in almonds and brown rice cereal. Stir until all three ingredients are well-mixed.
In a small saucepan over medium-low heat, add almond butter and maple syrup. Whisk until well incorporated. Stir occasionally, heating until this mixture begins to bubble.
Remove from heat and carefully pour over the dry mixture. Stir and fold until well-incorporated.
Pour into the prepared baking pan. Using a rubber spatula, smooth the rice crispy treats into an even, tightly packed layer.
Chill in the freezer for 30-40 minutes. Remove and slice into 16 square treats. Enjoy! Storing notes below.
