Ingredients

For white chocolate ganache:

  • 8 oz (227 g) white chocolate
  • ½ cup (130 ml) heavy whipping cream

For white macaron shells:

  • 100 g almond flour Note 1
  • 65 g powdered sugar Note 2
  • 70 g egg whites at room temperature Note 3
  • 75 g super fine granulated sugar Note 4
  • ¼ teaspoon cream of tartar optional Note 5
  • ¼ teaspoon salt
  • ½ teaspoon white gel food coloring

Instructions

To make the ganache filling:

  • Since the ganache filling requires long chilling time, we'll start with the filling.
  • Chop white chocolate into small pieces and place them in a heat-resistant bowl.
  • Heat heavy cream until nice and hot. (I microwave it for about 1 minute.) Pour the hot cream over white chocolate. Let stand for 2 minutes and the stir until chocolate is fully melted.
  • Using an immersion blender, blend the mixture until silky smooth, which means the mixture is emulsified. Cover with a plastic wrap, making sure it touches the surface of the ganache. Refrigerate for at least 5 hours, or overnight, to thicken and stabilize the ganache. After the chilling time, ganache should be nice and thick, and hold its shape when piped!

To make macarons shells:

  • Preheat the oven to 300°F (150°C). Line 2 baking sheets with parchment paper, or teflon sheet, or silicone mat.
  • To prepare dry ingredients, sift together almond flour and powdered sugar twice. (Note: If you have up to 2 tablespoons of chunky dry ingredients left in the sifter, you don't have to replace it. Simply discard those chunky bits.)
  • To make meringue, in a clean mixing bowl with a whisk attachment, combine egg whites, granulated sugar, cream of tartar and salt and beat the mixture on medium speed until soft peaks form. (I set it to speed 4 on my KitchenAid stand mixer. It takes 30-40 minutes to whip the meringue, but it's well worth it for nice and full shells.)
  • Add white gel food coloring when the meringue reaches soft peaks.
  • Continue beating the meringue at the same medium speed until hard peaks form. Visual cues: Meringue should ball up inside the whisk, and when you lift the whisk, the meringue should hold a pointy end and have sharp ribs.
  • To make batter, sift almond flour mixture into the meringue. Using a silicone spatula, fold the dry ingredients into the meringue until fully incorporated. Then continue to fold the batter until it's runny enough to draw a figure eight. To test, take a small amount of batter and drop it into the bowl. If the small peaks dissolve into the batter on its own in about 10 seconds, the batter is ready. If not, fold couple more times and test again. Be careful not to over-fold the batter. (TIP: Making french macarons is all about the technique. This is the most crucial step of all. Let me try to describe the folding motion as best as I can: run the spatula clockwise from the bottom, up around the sides and cut the batter in half. If you're beginner macaron-baker, I suggest to count every fold. It takes roughly about 50 folds to reach the proper consistency. After 50 folds, start testing the batter, and continue testing after every couple folds.)
  • To pipe macaron shells, transfer the batter into a pastry bag, fitted with a round tip. (I use this Wilton 2A tip.)
  • Hold the pastry bag at straight 90° angle and pipe about 1.5-inch rounds about an inch apart on prepared baking sheets. (TIP 2: Download my free macaron template. Simply pipe the batter to fill inner circle.)
  • Tap the baking sheets firmly on the counter (or slap the bottom of the baking sheet with one of your hands) a few times to get rid of any air bubbles. You can also use a toothpick to burst some large air bubbles. This step ensures smooth tops.
  • Let the macarons rest on the counter for 15 minutes before baking.
  • To bake, bake the macarons for 15-18 minutes, one baking sheet at a time, on the middle rack. It’ll take longer for larger macarons. To test for doneness, touch a macaron lightly and try to move it. If it slides and wobbles, bake a minute or so longer. The cooked macarons should be firm to touch and the base shouldn’t move.
  • Cool the macarons complete and then remove the shells from the baking surface. (TIP: Don't remove the shells while warm, you may risk breaking the shells, or the bottom might get stuck to the baking surface.)

To assemble macarons:

  • Transfer the ganache into a pastry bag with round tip.
  • Pair the macaron shells by size and arrange them on a wire rack.  Line them up so that bottom shells are upside down.
  • Pipe a dollop of filling on bottom shells. Place the top shell over the filling and press lightly so the filling spreads till the edges.
  • Refrigerate the filled macarons in an airtight container for at least 24 hours to mature, which allows the filling to soften and flavor the shells.
  • To serve, bring the macarons out about 30 minutes prior to serving.

Notes

Note 1: It’s best to use super fine almond flour to ensure smooth tops. Weigh the ingredients before sifting.
Note 2: I don’t recommend making your own powdered sugar, because commercial powdered sugar has cornstarch in it. And it helps with texture of the cookies.
Note 3: I’ve had success with carton egg whites (Bob Evans brand, #notsponsored). You’ll need 1/3 cup of egg whites.
Note 4: It’s important to use fine granulated sugar for meringue, as it dissolves quicker. You can also use caster sugar, aka baker’s sugar.
Note 5: Cream of tartar is optional and can be omitted. However, it helps to stabilize egg whites and create sturdier meringue. It’s just an extra insurance!
Note 6: You can easily double this macaron recipe.

Freezing Instructions: Freeze the filled macarons in an airtight container for up to 2 weeks. To thaw, place the frozen macarons in the fridge and let them thaw slowly for at least 1 hour. Then, bring them out 30 minutes before serving.
