A staple for many polymer clay artists! Here is a tutorial on how to make a simple, mini macaron.

The ones pictured here were made to be glued on ring bases to make macaron rings. However, you can leave them as is and use them as miniatures.

Materials

Polymer clay, in 2 colors. In this tutorial, I'm using Sophie and Toffee polymer clay in red and pink, or red and maroon. You can use any brand you wish (Fimo, Sculpey, etc.)
A needle tool (or a thick sewing needle)

Optional

A bottle of acrylic paint, or something similar to use as a platform to sculpt on
Any jewelry findings you may wish to have (ring bases, earring studs or hooks, etc.), with some sort of adhesive (super glue or E-6000)

Step 1: Shaping the Shell

Take a small ball of clay, and flatten it slightly. Using a needle tool, make an indent around the sides of your clay so that you create a thin border for the macaron feet.

TIP: Drag down from the top sides, so that the border ends up at the bottom of the macaron shell, slightly flared out.

Step 2: Making the Macaron Feet

Using your needle, make small, circular scratches on the bottom border of your clay ball to make the feet. This is a technique similar to what you would do texturing cakes.

Continue until you've textured entirely around your clay.

Flatten down your clay again, so you get a smooth, thin macaron shell.

Step 3: Matching Up

Repeat steps 1 and 2. Make sure that the amount of clay in your second macaron shell matches the amount in your first.

You can lightly place them together (don't press them together!) to make sure they're the same size.

Step 4: Adding the Filling

Now that you have 2 shells, it's time to add the filling!

Use another color of clay and make a flat disk that will just fit over the bottom macaron shell. It helps if this clay is very soft.

Place your top shell onto the filling. Carefully press together your macaron, enough so that the clay will stick together but not enough to cause any distortion.

TIP: If you wish to make these into charms, you can sandwich a headpin into the filling layer before adding your top shell and pressing together your macaron. You can also carefully use a thin needle to make a pilot hole through the top of your finished macaron, then add the headpin through this hole.

Step 5: Finishing Touches

You can leave this plain, or add any other details you wish to this. Here you can see one with a clay rose on top, and a candied rose petal on another. The rose petal can simply be made by flattening a ball of clay, and slightly curving the corners to look more natural.

Bake according to your clay packaging directions. Typically it tends to be around 275°F or 130°C, but be sure to read the directions on your clay specifically. The clay I'm using here bakes at 120°-130°C, slightly lower than the regular temperature.

TIP: Be careful to bake your clay thoroughly. Under-baking causes crumbly clay! Also watch your oven and beware of burning!

For the rose petal, glaze the petal, and dip it into transparent glitter. Brush off any excess glitter and let dry. Make sure that none of the glitter is on the macaron itself.

And you're done! You can superglue these to jewelry findings, or use them as miniatures!
