Step-by-Step Instructions

1. Preheat the oven
   Set the oven to 350°F. Line an 8×8 pan with parchment paper.

2. Melt the butter
   Melt and let it cool slightly. Warm is fine. Hot is not.

   Stir until smooth and glossy. This builds flavor.

4. Add egg and vanilla
   Mix well until the batter looks thick and creamy.

5. Add dry ingredients
   Stir in oat flour, cinnamon, baking powder, and salt. Stop once combined.

6. Spread the batter
   Press evenly into the pan. Take your time here.

7. Add the topping

8. Bake
   Bake until the edges are set and the center is soft.

   Let the blondies rest before slicing.

10. Slice and enjoy
    Soft, chewy Snickerdoodle Blondies are ready.

Common Mistakes to Avoid

• Overbaking – This dries them out

• Packing oat flour tightly – Light scooping matters

• Skipping parchment paper – Blondies love to stick

Avoid these, and you’ll get perfect blondies every time.
