These are some of my favorite macarons - light and airy with smooth vanilla flavor. I generally use Madagascar vanilla beans which tend to have more seeds and a stronger vanilla flavor. If you prefer more a more mellow and spicy vanilla flavor, try out Mexican vanilla beans instead. These are filled with my favorite mousseline buttercream recipe and are oh-so-amazing!
The Shells
3 Large Egg Whites, separated at least 24hrs in advance and kept in the fridge
210g confectioner's sugar
125g almond meal/flour
30g granulated vanilla bean sugar
1 Madagascar Vanilla Bean
1. Follow the Steps 1-7 for basic macaron shell recipe found HERE.
2. In step 8 pause to add your vanilla. Split the vanilla bean lengthwise and scrape out the seeds. This should end up being around 1/8tsp. Place the seeds in the egg mixture and gently fold in until evenly distributed.
3. Continue to follow the basic recipe steps 9-14 until the shells are completed.
The Filling
1lb (2 cups) unsalted butter, room temperature, cut in to 1" pieces
3/4 cup granulated vanilla bean sugar
1/4 cup granulated vanilla bean sugar (in a separate bowl)
1/4 cup water
5 large egg whites
1/4tsp cream of tartar
1 Madagascar Vanilla Bean, split with seeds removed
2tsp pure vanilla extract (or 2 additional vanilla beans)
1. In the bowl of a stand mixer, place egg whites. Premeasure your cream of tartar and 1/4 cup sugar and place nearby.
2. On medium-high heat, warm 3/4 cup sugar and 1/4 cup water until sugar is dissolved. Continue cooking until sugar reaches 200F on a candy thermometer. When you reach that temperature, turn your mixer on to begin beating the eggs.
3. When your egg whites become frothy, add the cream of tartar. Gradually add the 1/4 cup of sugar. Beat until egg whites form soft peaks and turn the mixer down to a low speed.
4. Once your boiling sugar mixture reaches 245F on the candy thermometer (firm ball stage), remove from heat and immediately drizzle in to the egg mixture while running the mixer at a low speed.
5. When all of the hot sugar is added, turn mixer to a high speed and continue beating until the bowl is no longer warm to the touch. This is essential to preventing separation once you add the butter.
6. Add the butter one lump at a time and continue beating until the mixture is smooth and fluffy. This takes about 12-20 minutes. It will look like ricotta cheese for a while, but don't worry & just keep beating.
7. Once the mixture is smooth, add in the vanilla bean seeds & vanilla extract. Mix until just incorporated.
8. Place your completed filling in a piping bag, on a cupcake, cake or whatever you want.
Keep at room temperature and do not refrigerate before it has been spread or piped.
Makes enough for 80 macarons, or enough to frost a 2-layer 8"-10" cake.
