Ingredients

Units Scale
  • Crust:
  • 18 (270 grams) full graham crackers
  • 1/4 cup (50 grams) granulated sugar
  • 1/2 teaspoon salt
  • 12 tablespoons (169 grams) unsalted butter, melted
  • Filling:
  • 2 cups (454 grams) fresh sweet potato puree (not canned)
  • 1/4 cup (50 grams) granulated sugar
  • 3 large eggs
  • 1 1/2 cups (356 grams) whole milk
  • 1/2 cup (119 grams) heavy cream
  • 1 tablespoon bourbon (or 1 teaspoon vanilla)
  • 1 teaspoon fine salt
  • 1 1/2 teaspoons ground cinnamon
  • 1/2 teaspoon ground ginger
  • 1/4 teaspoon ground cloves
  • Topping:
  • 2 large egg whites
  • 1/4 teaspoon cream of tartar
  • 3/4 cup (150 grams) granulated sugar
  • 1/2 cup (120 grams) light corn syrup
  • 1/4 cup water
  • 1/4 teaspoon salt
  • 1 1/2 teaspoons vanilla extract

Instructions

  1. Make the crust: Preheat the oven to 350°F. Line an 8×8-inch metal baking pan with foil, leaving an overhang. Pulse graham crackers, sugar, and salt in a food processor until finely ground. Add melted butter and pulse until moistened. Press into the prepared pan and bake for 10 minutes. Let cool completely. Maintain oven temperature.
  2. Prepare the filling: Beat all filling ingredients together with an electric mixer until smooth. Pour over the crust and bake for 40 minutes or until set but still slightly wobbly. Cool to room temperature.
  3. Prepare the marshmallow topping: Beat egg whites and cream of tartar until soft peaks form. In a small saucepan, bring sugar, corn syrup, water, and salt to a boil until it reaches 240°F. Slowly drizzle into the egg whites on low speed, then increase speed to medium-high and whip until glossy and marshmallow-like. Beat in vanilla.
  4. Assemble the bars: Spread marshmallow topping over the sweet potato layer. Toast with a kitchen torch or broiler until golden brown.
  5. Chill the pan for at least 1 hour before slicing into squares. Serve and enjoy! Bars can be stored in an airtight container in the refrigerator for up to 5 days.

Notes

  • Use freshly cooked sweet potatoes for the best flavor and consistency.
  • Keep a close eye when broiling to prevent the topping from burning.
  • Bars taste even better the next day as the flavors meld together.
