Preheat the oven to 350°F (180°C).
If using butter, melt it and let it solidify again at room temperature before using.
Beat ⅓ cup coconut oil or butter with ½ cup sugar in a bowl for a minute.
Add 1 egg and beat for another minute until well integrated. You can also use a whisk and stir energetically.
Sift the dry ingredients (1 cup all-purpose flour, 2 teaspoon baking powder and ¼ teaspoon salt) into a large bowl.
Combine the wet and dry ingredients, and mix until well integrated. Don’t beat at this point.
Add ½ cup chopped chocolate mini eggs and ⅓ cup ground almonds. Stir to combine gently.
Scoop or spoon tablespoon-sized portions of dough on a parchment-lined cookie sheet, leaving an inch and a half or two between them so they can spread during baking. I get 12 to 15 cookies.
Bake for 10 minutes, until they start to puff.
Remove the baking sheet and top the cookies with 36 whole chocolate mini eggs, dividing evenly (three for each cookie), pressing them very lightly. Do this quickly. I open the oven door and don’t completely remove the cookie sheet from the oven.
Return the baking sheet to the oven and bake for another 8 to 10 minutes, or until the edges are dry and the center is soft but springy. The eggs should not melt. The time will depend on the size of your cookies.
Let the cookies cool completely on a wire rack.
Store in airtight tins or cookie jars.
