The legality of Delta-8 THC varies by location, and individuals should be aware of and comply with local laws and regulations. Assuming that Delta-8 THC is legal in your area and you have acquired it from a reputable source, here is a basic recipe for making Delta-8 THC-infused brownies:

Ingredients:

• 1 cup (2 sticks) unsalted butter
• 1 cup granulated sugar
• 3 large eggs
• 1 teaspoon vanilla extract
• 1 cup all-purpose flour
• 1/2 cup cocoa powder
• 1/4 teaspoon baking powder
• 1/4 teaspoon salt
• Delta-8 THC tincture or distillate (make sure to measure and dose accurately based on product strength)

Instructions:

1. Preheat the Oven:
   Preheat your oven to 350°F (175°C). Grease a baking pan or line it with parchment paper.
2. Melt the Butter:
   In a saucepan or in the microwave, melt the butter.
3. Combine Wet Ingredients:
   In a mixing bowl, combine the melted butter and granulated sugar. Stir until well combined. Add the eggs one at a time, mixing well after each addition. Add the vanilla extract and mix.
4. Mix Dry Ingredients:
   In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt.
5. Combine Wet and Dry Ingredients:
   Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix.
6. Add Delta-8 THC:
   Determine the desired dosage of Delta-8 THC for each brownie, and add the appropriate amount of Delta-8 THC tincture or distillate to the batter. Mix thoroughly.
7. Pour into Baking Pan:
   Pour the brownie batter into the prepared baking pan, spreading it evenly.
8. Bake:
   Bake in the preheated oven for approximately 20-25 minutes or until a toothpick inserted into the center comes out with a few moist crumbs (but not wet batter).
9. Cool and Cut:
   Allow the brownies to cool in the pan before cutting them into squares.
10. Serve:
    Once cooled, serve and enjoy your Delta-8 THC-infused brownies responsibly.

Notes:

• Be cautious with Delta-8 THC dosing. Start with a low dose, especially if you are unfamiliar with its effects, and gradually increase if needed.
• Clearly label any cannabis-infused edibles and keep them out of reach of children and pets.
• Understand and comply with local laws regarding the use and possession of Delta-8 THC.

Remember to check and comply with your local regulations, and ensure that you are using Delta-8 THC responsibly and following the law.
