Step 1

Line an 8-inch (20 cm) square baking dish with parchment paper.

Step 2

Measure out all of your ingredients. This process moves quickly and you need everything to be ready to go so the marshmallow doesn't set before everything is added.

Step 3

In a large pan over medium-low heat, melt your fat (70 grams, 5 tablespoons) of choice. Alternatively, you can place it in a large microwave safe bowl, and melt it in the microwave.

Step 4

Add the mini marshmallows (297 grams, 10.5 ounce bag) to the pan and stir continuously with a silicone spatula until they are completely melted. Don't turn the heat up during this process as the final marshmallow treats can get hard if the marshmallow gets too hot. Alternatively, you can add the marshmallow to the bowl and microwave in 20 second bursts, stirring in between until fully melted.

Step 5

If using the salt (¼ teaspoon) and any flavorings, add them in with the marshmallow mixture here and stir to combine fully.

Step 6

Pour the cereal into your pan or bowl (if it isn't big enough you can pour the marshmallow into the cereal) and stir until fully combined. It will be very sticky and a bit difficult to stir, but stick with it!

Step 7

Fold in any solid mix-ins if using here.

Step 8

Transfer the mixture to your prepared dish. Lightly oil your hands or a silicone spatula and gently press the mixture evenly into the dish. IMPORTANT: Do not press it down too firmly, be very light. This will keep the treats nice and soft!

Step 9

Let sit at room temperature for 2 hours before slicing, or pop in the refrigerator for 30 minutes.

Step 10

Remove from the dish and slice into 16 squares (or 9 if you want very large treats)

Step 11

Store leftover treats in an airtight container at room temperature for up to 4 days.
