This recipe is from the food blogger “tasteandtellblog.com” and I want to share it as is, no tweaking.
Such a great idea to get that  concentrated pumpkin pie blast of flavor in a small bite.

Yields 48 pieces

1 1/2 cups sugar
2/3 cup evaporated milk
1/2 cup pumpkin puree (NOT pumpkin pie mix)
2 tbsp butter
1 tsp salt
2 tsp pumpkin pie spice
12 oz white chocolate chips
2 cups miniature marshmallows
1 tsp really good vanilla essence

Line an 8” by 8” baking dish with non stick aluminum foil.
In a medium saucepan, combine the sugar, evaporated milk, pumpkin, butter, salt and pumpkin pie spice.
Heat over medium heat.
Bring to the boil and allow to boil for 12 minutes, stirring often.
Remove from the heat and stir in the white chocolate chips and marshmallows.
Stir in the vanilla.
Pour into the prepared pan and chill until set.
Cut into squares.
