1-Step 1: Preheat and Prep Your Pan Start by heating your oven to 350°F (175°C). Grab an 8×8 inch baking dish and grease it lightly or line with parchment paper. This makes removal a breeze and keeps things nonstick. Why parchment? It prevents sticking and lets you lift the whole slab out for clean cuts.

2-Step 2: Mix the Dry Ingredients In a large bowl, whisk together the dry stuff: 1 cup rolled or quick oats, 1 cup vanilla vegan protein powder, 1 teaspoon baking powder, 1 teaspoon baking soda, ½ teaspoon salt, and 1 tablespoon pumpkin pie spice. Stir well so everything distributes evenly. This base gives structure and rise to your bars.

3-Step 3: Combine the Wet Ingredients In another bowl, mix ¼ cup maple syrup, 1 cup pumpkin puree, and ½ cup unsweetened oat milk. Whisk until smooth. Pumpkin puree adds moisture and nutrition, while milk keeps it batter-like. If it feels too thick, splash in a bit more milk.

4-Step 4: Bring It All Together Gently fold the dry mix into the wet until just combined. Don’t overmix, or bars might get tough. Spread the batter evenly in your prepared dish using a spatula. Smooth the top for uniform bars. Sprinkle 1 to 2 tablespoons dairy-free chocolate chips over the top if using, for melty pockets of joy.

5-Step 5: Bake to Perfection Pop it in the oven for about 20 minutes. Check with a toothpick; it should come out clean. Edges might brown lightly. Baking soda and powder make them fluffy yet firm.

6-Step 6: Cool and Cut Let cool completely in the dish, at least 30 minutes. Cooling sets the texture for clean slices. Cut into 16 squares. Store right away to keep fresh.
