Description
These chocolate marshmallow layer bars are a delightful treat with layers of chocolate ganache, marshmallow fluff, and graham crackers that create an indulgent dessert.
Ingredients
Scale
- 12 ounces semi-sweet chocolate chips (about 2 cups)
- 3 cups heavy cream (divided)
- 2 tablespoons powdered sugar
- 1/2 teaspoon vanilla bean paste (or 1 teaspoon vanilla extract, optional)
- 7 ounces marshmallow creme
- 1 box honey graham crackers
- 2 large egg whites
- 1/2 cup granulated sugar
- 1/4 teaspoon cream of tartar
Instructions
- Pour chocolate chips in a large, heat-safe bowl. Scald 1 cup (240g) of the heavy cream (I add it to a glass measuring cup and microwave for 45–90 seconds). Pour the hot heavy cream over the chocolate chips and cover the bowl with a clean lid (so no heat escapes). Let stand 5 minutes, then stir until smooth. This may take a few minutes. If needed, heat the mixture in the microwave in bursts of 10 seconds, stirring in between for 10 seconds until the chocolate mixture is completely smooth. Set aside at room temperature.
- Pour remaining 2 cups (480g) heavy cream, powdered sugar, and vanilla in the base of a stand mixer fitted with a whisk attachment. Beat on low for 30 seconds to combine and gradually increase until at full speed. Beat, watching carefully, until soft peaks form (about 2–4 minutes). Add all the marshmallow fluff and slowly beat to combine. Increase the speed to medium high until ingredients are combined and peaks are firm (about 30 seconds up to 1 minute). Set aside.
- Line a 9×9-inch baking pan with parchment paper (helps bars come out nicely). Spread a tiny bit of the marshmallow cream on the bottom (just enough to hold graham crackers in place). Spread an even layer of graham crackers and 1/4th of the marshmallow cream on top. Smooth with the back of a spoon into an even layer. Add 1/3 of the room-temperature chocolate ganache. Smooth with a table knife into an even layer.
- Add another layer of graham crackers, 1/4th of the marshmallow mixture, and 1/3 of the chocolate mixture. Add another layer of graham crackers, 1/4th of marshmallow mixture, and remaining 1/3 of chocolate. Add 1 last layer of graham crackers and the last 1/4th of the marshmallow mixture. You should be at the top of the pan. Cover the pan tightly and place in the fridge for at least 8 hours and preferably 12 hours.
- Optional Meringue: Place egg whites, sugar, and cream of tartar in a heatproof bowl. Set the bowl in a pot filled with 2 inches of simmering water over medium heat. Don’t let the bowl touch that water. Whisk constantly with a whisk until sugar is dissolved completely and the mixture has become bright white. (You can tell the sugar has dissolved by pinching off some of the mixture and rubbing it between your fingers, if you can feel a lot of sugar granules, keep mixing!)
- Transfer to a stand mixer (or use a hand mixer) and beat until stiff peaks form, about 5 minutes at high speed. Using a spatula, add dollops of the meringue all over the top of the cake. Gently coax the meringue to top the cake with the back of a spoon—this takes some patience to not lift up the top layer! Use a fork to run over the top, creating small rough ridges and peaks. If you have a kitchen torch, singe the peaks until lightly browned (move the kitchen torch along the meringue quickly—it will toast it very fast).
- Use the overhang of parchment to carefully remove bars from pan onto a cutting board. Use a sharp knife, run the knife under warm water, dry on a kitchen towel, and make decisive cuts. Repeat this process for each cut made.
Notes
- Make sure the ganache is completely cooled before adding it to the cake, or it will affect the texture of the marshmallow cream.
- Let the bars chill for a longer time for better consistency.
- If you do not have a kitchen torch, you can broil the meringue in the oven to achieve a similar toasted effect.
