First, take your 8x8 baking dish and line it with parchment paper. Make sure the paper hangs over the sides a bit - this will help you lift the fudge out later.
Get two saucepans ready. In the first one, put your semi-sweet chocolate chips and half of the sweetened condensed milk. Turn the heat to low and keep stirring until everything is melted and smooth. Once it's all melted, turn off the heat and stir in half of the vanilla extract and a pinch of salt. Set this aside.
In your second saucepan, put your white chocolate chips, peanut butter, the rest of the sweetened condensed milk, and the melted butter. Just like before, heat it on low and keep stirring until it's all smooth. Turn off the heat and add the rest of the vanilla extract and salt. Give it a good stir.
Now comes the fun part! Take both of your mixtures and start spooning them into your lined baking dish. Alternate between the chocolate and peanut butter mixtures - just drop spoonfuls wherever you like. Don't worry about being too neat.
Once all your mixture is in the pan, take a butter knife and gently drag it through the fudge to make pretty swirls. Don't stir too much - you want to see both colors clearly.
Put your pan in the refrigerator and let it chill for at least 2 hours. You'll know it's ready when the fudge feels firm to touch.
When it's completely firm, lift the fudge out of the pan using the parchment paper edges. Put it on a cutting board and cut it into squares. If you want neat cuts, wipe your knife clean between cuts.
There you have it - your very own homemade Peanut Butter Chocolate Swirl Fudge! Don't worry if your swirls aren't perfect the first time - mine weren't either, and guess what? They still tasted amazing! Each batch you make will be unique, and that's part of the fun.
This fudge has become my favorite thing to make when I need a special treat. It's perfect for sharing with friends, bringing to parties, or just keeping in the fridge for when you need a little something sweet.

Remember to store your fudge in the fridge in an airtight container - if it lasts that long! In my house, it usually disappears within a day or two.
