Preheat & Prep Set your oven to 325°F (163°C). Line an 8-inch square baking pan with parchment paper so the edges hang over slightly for easy removal.
Warm the Nut Butter If your almond butter is stiff, gently warm it (microwave 20 seconds) until smooth and stirrable. This helps everything mix evenly.
Mix the Batter In a large bowl, whisk together pumpkin puree, almond butter, vanilla, cocoa, protein powder, sugar, salt, and pumpkin spice until completely smooth. The batter will be thick and glossy — that’s perfect.
Pour & Bake Spread the mixture evenly into your pan. Press a few chocolate chips on top if you like. Bake on the center rack for 20–25 minutes.
For fudgy brownies: remove at 20 minutes.
For cakier brownies: leave closer to 25.
They’ll look slightly underbaked when done — trust the process.
Cool & Set Let them cool completely, then loosely cover with a paper towel and refrigerate overnight. The texture deepens and sweetens by morning, turning dense, rich, and fudgy.
