These delightful macarons just melt in your mouth and are delicious.  My whole family loved them.  We brought them to a party.  I helped my mom make these.  
Orange Chocolate Macarons
adapted from What a Dish!
110 g almonds 
meal/flour
200 g powdered sugar
1 scant teaspoon 
powdered 
orange food coloring
50 g granulated sugar
100 g egg whites (about 3 egg 
whites), aged (left out) a day at room temperature
1. Line 2 baking 
sheets with parchment paper or silicone mats. 
2. Pulse almond flour, 
powdered sugar, and powdered food coloring in a food processor until evenly 
mixed. Split the vanilla bean in half lengthwise, and scrape the seeds out using 
a paring knife. Add the seeds to the granulated sugar and whisk to 
combine.
3. In the bowl of a stand mixer fitted with a whisk attachment, 
whip the egg whites until foamy, then gradually add the granulated sugar and 
continue to whip until a shiny, stiff, glossy meringue forms (but not 
dry).
4. Remove the bowl from the stand mixer, and add the almond 
mixture. Using a rubber spatula, briskly and quickly fold the almond meal into 
the egg whites. After a few brisk strokes, slow down and then gently incorporate 
the rest into the batter.You want a batter that flows and "ribbons" for at least 
5 seconds.
5. Pour the batter into a pastry bag fitted with a large round 
tip (I use Wilton 12). Pipe the batter into 1 1/2-inch rounds, spacing them 
about 1-inch apart. Whack the baking sheets on the counter a few times, then 
allow to sit at room temperature for about 1 hour, or until a hard shell forms.  
(While you wait, prepare ganache, below.)
6. Meanwhile, preheat the oven 
to 280 degrees. Bake the macarons 10-12 minutes, depending on size.  (Should be 
dry and lift away easily from parchment when done.)  Allow to cool completely on 
the pan before using a small spatula to remove them. Match the cookies according 
to size and pipe filling on half, using the other half to form a sandwich.
Dark Chocolate Ganache
6 oz. mini semi-sweet 
chocolate chips
3/4 cup heavy cream
1.  Place chocolate in a 
heatproof bowl.  In a small saucepan, over medium heat, heat and stir the cream 
until it barely comes to a simmer.  Immediately pour over chocolate in bowl and 
cover bowl.  Let stand for 5 minutes.  
2.  Then, whisk until 
combined and smooth.  It might take a little bit, but it should turn dark, 
smooth, and shiny.  Set aside to cool until needed.  I set it in the fridge, 
since it needs to be on the thick side for the filling.
