I encourage you to check out the step-by-step photos for the crust below this recipe before beginning.

Preheat the oven to 350°F (177°C). Using a food processor, pulse 3/4 cup peanuts, the flour, brown sugar, and salt together until it reaches the consistency of coarse meal. Add the cubes of cold butter and pulse until the mixture turns into pea-sized crumbs. Transfer mixture to a large bowl. Slowly stir in 3 Tablespoons of ice water. You only want to add enough water to bring the dough somewhat together. Using floured fingers or the bottom of a flat and lightly floured measuring cup, press the dough evenly into a 9-inch tart pan. You want it extremely tight in the pan. You’ll need to use pie weights for the next step, so line the crust with aluminum foil or parchment paper and add pie weights. If you do not have pie weights, prick the crust a few times with a fork so no air bubbles form.

Bake (with pie weights) for 18-20 minutes. Remove from the oven and allow to slightly cool as you prepare the filling.

Mix the salted caramel and 1 cup of peanuts together. If the salted caramel was made ahead of time, slightly warm it so that it can easily be poured. Pour caramel nut filling into crust.

Using a double boiler or microwave, melt the chocolate and peanut butter together until smooth. If using the microwave, stop and stir every 15 seconds until melted. Spread over caramel nut filling. Garnish with optional toppings, if desired.

Chill in the refrigerator, uncovered, for 2-3 hours or until set. Store leftovers in the refrigerator.
