Halve the Oreos. I find it helps prevent cracks if you cut them swiftly.

Melt the dark chocolate.

Place the dark chocolate in a piping utensil / bag.

Pipe chocolate onto the parchment paper in the width and height of the cut side of the Oreo.

Stick the halved Oreo on top of the chocolate and push it down so the chocolate spreads out.

Pipe the butterfly's half-8 shaped wings to each side.

Top with a large and small blueberry.

Add two small blobs of dark chocolate on top of the Oreo.

Place two mini candy eyes onto the blobs.

Allow the chocolate butterfly to set.

Serve.
