Preheat your oven to 350°F and line an 8" x 8" baking dish with parchment paper.
In a large bowl mix together the base ingredients. First, mix the dry ingredients and then add the wet ingredients. Combine with a rubber spatula.
½ cup almond flour, ½ teaspoon baking powder, ⅛ teaspoon salt, ¾ cup powdered sweetener sugar substitute, 3 large eggs, ¾ cup unsalted butter, 1 teaspoon vanilla extract
Separate the base ingredient in half using two medium bowls. In the first bowl add the cocoa powder and espresso powder, mixing until fully combined. Then add the chocolate chips and mix until well incorporated.
¼ cup cocoa powder, 1 teaspoon espresso powder, ½ cup sugar free chocolate chips
In the other bowl add the pumpkin puree and the pumpkin spice to the base mixture and mix until well combined.
¼ cup pumpkin puree, 1 teaspoon pumpkin spice
Spread the chocolate base mixture evenly into the prepared baking dish. Next, carefully spoon the pumpkin base mixture on top of the chocolate base. Use a butter knife to create a swirling pattern by gently running it through the two layers. This will create a beautiful marbled effect.
Place the baking dish in the preheated oven and bake at 350°F (175°C) for approximately 45 minutes or until a toothpick inserted into the center comes out clean. Allow it to fully cool in the baking dish before removing. Cut into squares and enjoy. (see video)

Notes
Note: For a fudgier consistency, cut the brownies into squares, place them in a dish, cover it with plastic wrap, and allow them to rest for at least 2 days before enjoying. This resting period allows the brownies to develop a denser, more indulgent texture that many brownie enthusiasts adore. Your patience will be rewarded with brownies that are delightfully rich and fudgy. Enjoy the improved texture after this brief period of waiting!If you prefer your brownies to be thicker and more indulgent, feel free to double the recipe ingredients. Be sure to increase the baking time accordingly to ensure they are cooked through. Keep an eye on them and use a toothpick test to determine when they're done. Thicker brownies may require a few extra minutes in the oven to achieve that perfect fudgy consistency.
