Preheat your oven to 350°F (175 °C).
In a food processor or a small blender, process the whole almonds until they're finely ground. You want a texture that is similar to that of almond flour (refer to the photos above). Transfer to a large mixing bowl.
1.5 cups almonds
Add the cacao powder to the ground almonds and mix well until the almond grains are coated with the cacao powder and there are no large clumps.
3 Tablespoons cacao powder
Gently pour the melted coconut oil and agave syrup to the mixture. Mix well.
3 Tablespoons coconut oil, melted, 2-3 Tablespoons agave syrup
Divide the dough into 6 equal parts, about 2 heaping Tablespoons each. Then roll each part into a ball. Place each dough ball into each tartlet pan, then use your hands to press to flatten, making sure that the sides are pressed into the wavy edges.
Bake the crust in the oven at 350°F (175 °C) for 10 minutes. Pierce the bottom with a fork a couple times to that the bottom crust stays flat. You can also use baking beans or rice.
