*I haven't tried this, but I'm sure you could use
THM Baking Blend in place of my Baking Mix. I would use 2 cups, then add more if you think the batter needs to be thicker. It's not a runny batter, but it should be easily spreadable.
I bet you could bake this in 2 or 3 9-inch cake pans (adjust the baking time) and frost with the browned butter frosting. Top with pecan halves and drizzle with Pumpkin Spice Syrup for a pretty finish.
