Watch our video below to see exactly how we made them, then follow the step-by-step recipe underneath.

What you will need:

This recipe makes approximately 8–10 double hearts depending on your cutter size.

2 x 50g of Rice Krispies
2 x 150g white cooking chocolate
1 x mixing spoon and brush for edible glue
1 x lined baking tray
1 x edible glue

Important: Always use gel food colouring rather than liquid colouring when working with chocolate — liquid colouring will cause your chocolate to seize and become unusable.

How To Make Grinch Heart Rice Krispie Recipe — Step By Step

Step 1 — Make the green hearts
Measure 50g of Rice Krispies into a bowl. Melt 150g of white cooking chocolate in the microwave in 30-second bursts, stirring between each, until fully melted. Add green gel food colouring and stir until you reach a deep, dark Grinch green. Pour the chocolate mixture over the Rice Krispies and stir until every krispie is coated. Tip onto one half of a lined baking tray and press down firmly and evenly using a piece of baking paper.

Step 2 — Make the red hearts
Repeat the process with the remaining 50g of Rice Krispies and 150g of white chocolate, this time adding red gel food colouring. Pour onto the other half of the lined baking tray and press down evenly.

Step 3 — Chill
Place the tray in the fridge for around 20 minutes until both mixtures are completely set and firm.

Step 4 — Cut the hearts
Remove from the fridge. Press the large heart cutter firmly into the green mixture and lift out — repeat until you have as many green hearts as possible. Press the small heart cutter into the red mixture and lift out — repeat to match the number of green hearts.

Step 5 — Assemble
Using a small brush, apply a thin layer of edible glue to the bottom of each small red heart. Press firmly onto the centre of a large green heart and hold for a few seconds until set. Repeat until all your hearts are assembled.
And that’s it, you now have a plate of Grinch hearts ready to share. Or not share. We won’t judge.

Whether you’re making these for a Christmas party, a baking afternoon with the kids or simply because the festive spirit moved you, these Grinch-inspired hearts are guaranteed to make people smile.

Stack them on a plate, wrap them in cellophane tied with a red ribbon, and they make the most brilliant little edible gift too.
