Creating these Sweet Potato Crème Brûlée Bars involves a few simple steps that will guide you through the process:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking pan.
2. Prepare the Sweet Potatoes: If you haven’t already, cook your sweet potatoes until tender. Mash them until smooth and set aside.
3. Mix the Custard: In a large bowl, whisk together the heavy cream, granulated sugar, egg yolks, vanilla extract, cinnamon, nutmeg, and salt until well combined.
4. Combine Mixtures: Fold the mashed sweet potatoes into the custard mixture, ensuring everything is well mixed and smooth.
5. Pour into the Pan: Pour the sweet potato custard mixture into the prepared baking pan, spreading it evenly.
6. Bake: Place the pan in the preheated oven and bake for 30-35 minutes, or until the custard is set and a toothpick inserted comes out clean.
7. Cool: Remove from the oven and let the bars cool in the pan for about 1 hour. Then, refrigerate for at least 1 hour to allow them to firm up.
8. Caramelize the Sugar: Before serving, sprinkle the top of the bars with 1/2 cup of granulated sugar. Use a kitchen torch to caramelize the sugar until golden and crispy. If you don’t have a torch, you can place the bars under the broiler for a few minutes, but watch closely to avoid burning.
9. Slice and Serve: Once the sugar has caramelized and cooled, slice the bars into squares for serving.

With these straightforward steps, you’ll be well on your way to creating delicious Sweet Potato Crème Brûlée Bars that are sure to impress!
