2cupssweetened peanut butter (Like Peter Pan or Jif)(520 grams)
1cupsugar(200 grams)
2largeeggs(100 grams)
1cupchocolate chunks, peanuts, or peanut butter chips (mixed)(optional)
Topping
¾cupsemisweet chocolate chunks, chips or chopped chocolate4 oz
Instructions
Preheat the oven to 350 degrees. F. Line a 9x13 inch pan with parchment. If making a half batch, use a mini sheet pan.
Melt the 4 oz of semisweet chocolate in the microwave or in a bowl set over simmering water.
While the chocolate is melting, beat the peanut butter, sugar and eggs for two minutes. The batter will be fairly thick. Spoon out 1 cup of peanut butter mixture and set aside.
Add slightly cooled melted chocolate to the peanut butter mixture in the mixing bowl and beat on low speed to mix.
Scrape the chocolate batter into the pan and press it into an even layer. Make sure it is cool, then sprinkle chocolate chunks and/or some peanut butter chips over and press them into the dough.
Crumble the reserved peanut butter mixture over the chocolate layer and gently pat it down. It won’t fully cover the chocolate, so just press it in patches. Sprinkle with more chocolate chips, peanut butter chips and peanuts if using.
Bake for about 25 to 30 minutes. When done, the center should look set but still slightly soft; a toothpick inserted into the chocolate layer will come out with moist crumbs.
Let cool, then melt the remaining 4 oz of chocolate (or chips) and drizzle over the top. Score while slightly warm, then put in the freezer to set the chocolate.
