Use a sifter to combine almond flour and powdered sugar into a bowl. Make sure the mix is smooth without lumps. Put it aside for later.

Grab a clean bowl and start whipping the egg whites with a hand or stand mixer. Begin slow, then pick up the pace to medium-high. Once you see soft peaks forming, slowly add the granulated sugar while mixing. Keep beating until the peaks are stiff.

Fold the almond flour and powdered sugar mix into the whipped egg whites using a spatula. Add food coloring if you like. Stir gently so it flows off the spatula in thick ribbons, like lava.

Scoop the batter into a piping bag with a round tip. On a baking tray lined with parchment, pipe hearts by drawing a 'V' for each one. Try to keep the sizes even so they bake properly.
05 -
Set the piped hearts somewhere to sit for 30 minutes to 1 hour. A dry surface should form on top, which helps develop the macaron 'foot.'

Preheat the oven to 300°F (150°C). Place the rested macarons into the oven and bake for about 18–20 minutes. They should lift easily off the parchment and feel firm.

Use a medium bowl to beat the butter until smooth and fluffy. Gradually add powdered sugar a bit at a time, mixing after each addition. Stir in vanilla and a pinch of salt. Add milk or cream one tablespoon at a time until it’s creamy and spreadable. If you want, add a few drops of red food coloring.

Let the shells cool completely. Flip them over and pipe a bit of buttercream on the flat side of one. Press another shell on top to make a sandwich.

Put the macarons in the fridge for at least 24 hours. This lets the filling soften the shells, making them even tastier.
