Brownie Batter
4–5 honey graham cracker sheets
10 tbsp unsalted butter
⅔ cup + ¼ cup dark chocolate chips
½ cup dark brown sugar, packed
½ cup granulated sugar
2 large eggs
1 large egg yolk
2 tsp vanilla extract
⅔ cup + 1 tbsp all‑purpose flour
¼ cup unsweetened Dutch‐process cocoa powder
1 tsp espresso powder (optional)
¼ tsp fine sea salt
½ cup chopped dark chocolate
Homemade Marshmallow
⅓ cup water
4½ tsp gelatin powder
1⅛ cups granulated sugar
¼ cup + 1 tbsp agave syrup (or honey/corn syrup)
⅓ cup water
1 tsp vanilla bean paste
¼ tsp fine sea salt
Preheat oven to 350 °F (180 °C). Line an 8×8″ square pan with parchment.
Arrange 4–5 graham crackers in a single layer on the bottom.
Melt butter and ⅔ cup + ¼ cup chocolate chips until smooth; set aside to cool slightly.
Whisk together sugars, eggs, egg yolk, and vanilla until combined. Stir in melted chocolate.
Fold in flour, cocoa powder, espresso powder, and salt until just mixed.
Pour batter over the graham crackers and bake for 30–35 min (33 min ideal); cool 1–2 h.
Once cool, melt chopped chocolate and spread evenly over the surface; lightly oil parchment sides to prevent sticking.
For marshmallow: bloom gelatin in ⅓ cup water in mixer bowl.
Boil sugar, agave, and ⅓ cup water to 240–250 °F; with mixer on low, stream syrup into gelatin (avoid whisk contact); add vanilla paste and salt.
Whip on medium for 10–15 min until thick and room temperature.
Spread marshmallow over the brownies quickly; let set ≥4 h.
Preheat broiler or use a kitchen torch to toast marshmallow until golden.
To cut: dust with powdered sugar, heat and oil knife, cut into sections, cleaning between cuts.
Serve and enjoy!
