Preheat the oven to 350 degrees Fahrenheit and grease the top of a cupcake pan (in case the cupcake tops come over the sides when rising, they won't get stuck to the pan), then line the pan with cupcake liners. Set aside. In a medium-sized bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder and salt until completely combined. Set aside.

In the bowl of an electric mixer fitted with the paddle attachment, mix the buttermilk, olive oil, eggs, vanilla extract, and coffee extract at a low speed until well-blended. Slowly add the dry ingredient mixture to the mixing bowl, continuing to beat at a low speed and scraping down the sides of the bowl as necessary. Add the cup of chicory coffee and continue mixing until it is just combined. Distribute the batter into the cupcake liners, filling them up about 2/3rds of the way (they will rise when baking). Place the pan in the oven and bake for 25-30 minutes or until a toothpick inserted into the center of a cupcake comes out clean. Place on a wire rack to cool.

While the cupcakes are baking, you can start making the frosting. Melt down the chocolate in a double boiler over simmering water until it has just completely melted. Remove from heat and set aside to cool to a very slightly warm temperature. (Now, it is very important that the egg yolks and butter are at room temperature when you start making the frosting. If they are cold, then when you add the melted chocolate the chocolate will begin to solidify and you will end up with hard chunks of chocolate in your frosting rather than a nice and smooth buttercream). Beat the butter with the paddle attachment at medium-high speed until pale and fluffy, about 3 minutes. Add the egg yolks, vanilla extract, and amaretto liquor and beat the mixture for 3 minutes more. Bring the speed to low and slowly add the powdered sugar. Once the powdered sugar has been incorporated, bring the speed up to medium and beat until smooth and fluffy. Bring the speed back down to low and add the melted chocolate and continue beating until the chocolate is just incorporated and the frosting is smooth, taking care not to over beat the mixture and scraping down the bowl as necessary.

When the frosting is done, immediately begin frosting the cupcakes. Then place the decorative sprinkles in a small bowl and, holding the frosted cupcake upside down, gently roll the exposed frosted top in the sprinkles. Hold it upright again to display your thoroughly sprinkled cupcake. Repeat and enjoy!
