Place all ingredients into a food processor. Pulse until well combined and the mixture looks like flour.

Store in an airtight container.

Melt white chocolate either double boiler style or microwave.

Portion out a small amount of the chocolate unto a separate bowl and add powdered pigment. Mix until you are happy with the shade.

Freehand paint a heart shape or cut a template out of parchment paper. Place the template inside the center of the dome cavity (I used mold with cavities 2" wide) and paint with the pink chocolate over the negative space. Repeat in the desired cavities. Place in the fridge to set for about 5 minutes.

Remove from fridge and paint the entire surface of the cavities with the white melted chocolate. For the first coating, be careful painting over the heart if the chocolate is warm.

After the first coating, return to fridge to set for about 10 minutes.

Then apply the second coating of chocolate and return to fridge.

To set the marshmallows in the domes, dip each marshmallow in the white chocolate and place it one of the domes. Make sure that none are taller than the dome edge. Place in the fridge to set.

To assemble the bombs first wear some disposable gloves: remove the molds from the fridge and gently lift the domes from the cavities. I recommend returning the domes back to the fridge when not working on them and keep out only the two opposing sections. White chocolate melts at a faster pace than other types of chocolate so keeping it cool when not in use is essential.

Place the non marshmallow dome on a stand: I use a cookie cutter or small bowl that has a rolled edge. Fill the dome with 1 to 2 tablespoons of white chocolate and peppermint mix.

Take the marshmallow dome and and melt the bottom a little and then quickly but gently place it over the other dome to create a sphere.

To seal the seam, paint it with white chocolate. To get a nice even seal, use a heated offset spatula to clean up any lumps or bumps.

When finished, you can brew a cuppa by placing the bomb in a coffee mug. Pour 6 oz to 8 oz of very hot milk over the bomb then stir and enjoy! Or place the bombs in a cupcake liner and package in a beautiful container to give to loved ones.
