Place the red candy melts in a microwave-safe bowl and heat on high, in the microwave, for 2-3 minutes or until smooth when stirred. Stop every 15-30 seconds to stir during the melting process to ensure the candy melts don’t overcook.
Follow step one for the pink candy melts, keeping the two colors separated.
Remove the lid and film from the frosting and place it in the microwave for 45 seconds to 1 minute, or until fully melted and smooth. Set aside ½ a teaspoon of uncooked frosting if using the heart sprinkles.
Add the extract to the frosting and stir well.
Place half of the frosting in with the red candy melts and the other half with the pink candy melts.
Stir each color vigorously until fully mixed.
Line your 8x8 pan with parchment paper, making sure to leave some overhang.
Alternate pouring in the two colors in random spots, pausing to tap the pan in between so it evens out and removes bubbles.
Once all your chocolate mixtures have been poured in and evened out, sprinkle the top of the fudge with as many Valentine’s themed non-pareils as you like.
Place in the fridge to chill for 2 hours or until hardened.
If desired, use the set aside frosting and place a dab on the back of a heart sprinkle, and press it into the middle of each fudge square you cut for a cute addition! Enjoy!
