Tender, buttery graham cracker shells cradle a creamy layer of peanut butter filling. Topped with a rich chocolate ganache and torched marshmallows, each luscious bite will keep the summertime good vibes going for a little while longer.
Preheat the oven to 325°F / 163°C. Use a food processor to grind the graham crackers, or place them in a sealed plastic bag and hammer them with a rolling pin. Mix the graham cracker crumbs, sugar, and melted butter in a medium mixing bowl until thoroughly combined.
Spread the mixture equally among 4 - 4" tart shells. Press the mixture along the bottom and sidewalls of each to form a crust. Place the shells on a baking pan. Bake on the center rack for 10-15 minutes until lightly golden. Remove from the oven and allow to cool completely. The crust will firm as it cools.Note: If the shells are puffy when you remove them from the oven, gently press the crust back down with the bottom of a glass before allowing them to cool.
Peanut Butter Filling
Mix PBfit™ and water in a large mixing bowl with a rubber spatula until combined--it should resemble creamy peanut butter. Stir in the cream cheese until fully combined. Fold in the powdered sugar.
Combine the cream and vanilla in a medium mixing bowl. Whip with a hand or stand mixer--or by hand with a whisk--until stiff peaks form.
Fold the whipped cream into the peanut butter mixture until thoroughly combined. Spoon equally into the 4 cooled tart shells, leaving ¼" from the rim. Refrigerate for 30 minutes.
Chocolate Ganache
Once the tarts have been in the fridge for 30 minutes, combine the chocolate and cream in a microwave-safe bowl. Heat in 30-second increments on 50% power, stirring each time, until the chocolate is melted and silky smooth.
Assembly
Spoon 1 ½ - 2 Tablespoons of the ganache over each tart, spreading in a circular motion using the back of the spoon until most of the peanut butter filling is covered. Add a mound of marshmallows in the center, covering most of the ganache. Refrigerate for 2 hours. When ready to serve, gently remove the tarts from each pan. Use a torch to toast the marshmallows on the top. Alternatively, you can stick the tarts under a preheated broiler to toast the marshmallows, but you'll want to cover the entire surface of each tart with them. Otherwise, the filling and ganache may liquify if exposed to the heating element.
Notes
I recommend adding the marshmallows immediately after you spoon the ganache on the PB filling. This will allow the marshmallows to set into the filling as the tarts chill.Please Note: Nutrition Facts are estimates only.
