You start by gently melting chocolate chips. If you’re too aggressive with the heat, the chocolate will “bloom” which means turn a whitish colour. It doesn’t affect the way it tastes but it doesn’t look great. That’s why a double boiler or very very low heat works best. You can also melt the chocolate in a microwave, just make sure to use short bursts of a lower power setting.

Chocolate chip package sizes are sneaky. Normally they are priced the same but the better quality chocolate will be in slightly smaller packages while the cheaper chocolate will be larger. US sizes differ from Canadian sizes too so look for 12 oz or 340 grams. You need about 2 cups. Once the chocolate is melted, stir in the peanut butter. Smooth works the best.

If you don’t already know this, the easiest way to measure ingredients like butter, shortening, peanut butter etc (those that are fat based so non water soluble) is to add them to cold water and use water displacement as your measurement tool. So, if you need ½ cup of peanut butter, fill a clear measuring cup with 1 cup of cold water, then immerse peanut butter by the spoonful until the water level comes up to 1 ½ cups. You have to get eye level with the measuring cup to be accurate. See? We did learn something in science class!

The secret ingredient? Marshmallows.

Marshmallows magically turn this mixture into a fudge like texture. Use the white mini marshmallows, not the coloured type, they have a funky flavour.

The mixture will get thicker and thicker as the marshmallows melt. It gets pretty hard to stir at the end. But the upside is, it doesn’t stick to the pot. Once there are no white streaks left, press the fudge into a square baking dish lined with parchment paper.

Allow your Chocolate Peanut Butter Fudge set at room temperature. You can refrigerate to cool it faster, however, remember how chocolate blooms at higher heat? It also blooms at cold temperatures. That’s why it’s important to be patient.

Lining the pan with parchment paper lets you lift the fudge out so you can easily cut it into squares. Or, if you’re making these for your Valentine, cut them into heart shapes. They make a great gift and are sure to score you some extra points!
