Position a rack in the center of your oven and preheat the oven to 350 F. Coat an 8-inch square baking pan with Sizzle. Line the pan with a strip of parchment paper that hangs over two of the edges.

In a large bowl, whisk the brown sugar and eggs until pale and foamy, about 1 minute. Add the pumpkin puree, Sizzle, cinnamon, cardamom, allspice, pepper, and kosher salt. Whisk until smooth and emulsified.

Add the flour, baking powder, and baking soda and whisk until well-combined and smooth. 

Pour the batter into the prepared pan, tap the pan gently on the counter to release any air bubbles, and smooth the top of the batter with an offset spatula. Sprinkle the pepitas over the top if you are not going to glaze the cake. 

Bake until puffed and golden, and a tester inserted into the center comes out clean, 25 to 35 minutes. Set the pan on a rack to cool for about 15 minutes. Then use the parchment paper to lift the cake out of the pan and set it on the rack to cool completely. 

Make the glaze by combining the confectioners’ sugar, Drizzle, maple syrup, 1 tbsp of the hot water, and a pinch of kosher salt in a medium bowl. Whisk until smooth, adding more water as necessary to make a thick but pourable glaze. 

Pour the glaze over the cooled cake and sprinkle with the pepitas and flaky salt (if desired). Let the glaze set for about 20 minutes before slicing the cake. (Store the cake, well wrapped, at room temperature for up to three days.) 

Extra Tips:
