Before you start, get all of the ingredients ready. Prepare a large piping bag, fitted with a large round tip.
Measure out all of the ingredients.
Sift the powdered sugar and almond flour together. Set aside.
Place the egg whites and granulated sugar in a heat proof bowl or in a double boiler. Over a pan of simmering water, whisk the whites and sugar until frothy and sugar completely melted. It will take a couple minutes.
Make sure the bottom of the bowl isn’t touching the simmering water.
Transfer the mixture to the bowl of a stand mixer.
With the whisk attachment, whisk the mixture on low, and gradually increase the speed over the next 2 minutes, until you achieve high speed. Then continue to whip for a few minutes until stiff peaks are formed.
Best way to check this is to keep your eye on the whites. Once they get glossy and you start seeing streaks formed by the whisk, it might be time to stop.
Whisk until stiff peaks have formed. When you pull your whip up, the peaks should be shooting straight up. The peak should be stiff, forming a slightly curved shape at the top, but not bending down to the side.
Pour the powdered sugar, almond flour, and cocoa powder into stiff whites.
It’s time to stop folding when the batter is glossy and has a thick and flowing consistency. There are several ways to test this.
First, pick up some batter with the spatula and try to form a figure 8 a few times. If you can draw a figure 8 with the batter falling off the spatula a few times, without the batter breaking up, that’s one indication that it might be ready.
Then, you can perform what I call the Teaspoon Test. Grab a teaspoon of batter and spoon onto the parchment paper or silicon mat, then tap the tray gently against the counter and wait one minute.
If the batter stays stiff and doesn’t spread out a bit, fold the batter a bit more, then test again.
Once the batter spreads out a bit and starts to look glossy on the parchment paper, I transfer my mixture to the piping bag.
You don’t want your batter to be too runny either. So be careful not to overmix. It’s always best to undermix and test several times until the proper consistency has been achieved.
Let the trays sit for a while so the shells will dry out a little bit. I usually leave about 20-40 minutes, depending on how humid the day is. You’ll know they’re ready when you gently touch the surface of a macaron and it seems dry.
Bake for 5 minutes, rotate tray.
Bake for 5 more minutes, check if it needs to be rotated again. You will know if it needs to be rotated again depending on how the macarons are baking. Take a look at them, if one side seems taller than the other, maybe you have to rotate the tray again.
Bake for around 4 more minutes or so. I would say I bake for a total of 15 to 20 minutes. Until you try to move a macaron and it doesn't feel jiggly.
When baked, the macarons will have a deeper color and formed feet. And they will peel off the tray easily.
Scale: Please use a scale when measuring the ingredients for accuracy.
Macaron amount: it will vary greatly depending on how big you pipe the shells, and on how runny or thick the batter is.
Baking time/temperature: Baking time and temperature will vary according to your own oven. I recommend experimenting with your oven to find out the best time, temperature, position of the baking tray.
Oven thermometer: Make sure to have an oven thermometer to bake macarons. It’s one of the most important things about making macarons. Home ovens aren’t accurate at all at telling the temperature, and even a slight 5 degree difference can make or break your whole batch.
Tray rotation: Lots of bakers don’t have to rotate the trays 180 degrees in the oven every 5 minutes, but I do have to with my oven, or I will get lopsided macarons. Please adjust this according to your oven.
