Wrap the 12-inch styrofoam cone with two layers of plastic wrap.

Position the wrapped cone upright and push a toothpick halfway into the cone starting at the bottom.

Gently place a donut hole onto each toothpick.

Insert the next toothpick near but not touching the previous donut hole and place donut holes on these toothpicks, continuing around in a complete circle to cover the bottom row.

For new rows, tuck the donut holes in between the ones below to fill gaps and maintain a tree shape, continuing upwards until the entire cone is covered.

Trim small pieces of fresh rosemary and place them in gaps for decoration.

Scatter pomegranate arils throughout the tree and dust with powdered sugar.
