30 Saltine crackers, finely crushed in a food processor or blender (see notes)
1 teaspoon vanilla
1¼ cup peanut butter
1½ cups chocolate chips
coarse sea salt
Crush the crackers into fine crumbs, depending on how much texture you want in your fudge. Place in a large mixing bowl with the peanut butter.
Combine the sugar, milk, and butter in a saucepan over medium low heat. Once the mixture starts boiling, turn on a timer for 1 minute. The mixture will look a little frothy. Remove from the heat after 1 minute and pour immediately over the crackers and peanut butter. Add the vanilla and stir to combine until an even, soft dough forms.
Press the dough into a 9-inch glass baking dish (or other dish) lined with parchment paper if desired. Allow to cool for at least 1 hour or until firm enough to cut into squares - it sets up pretty quickly in the refrigerator.
Melt the chocolate chips and drizzle over the fudge. Sprinkle with sea salt.
Here's a link that shows the size of crackers that I used. I didn't break them apart - I just counted the sheets with three smaller pieces as one cracker.
