TOOLS I USED FOR THIS RECIPE:

  • KitchenAid 6 Qt. Stand Mixer – I always recommend a stand mixer as it saves time and helps to keep baked goods consistent.
  • Rubber Spatula – a must for any home baker! Perfect for scrapping cookie dough out of the mixing bowl.
  • USA Pan 8? Square Pan – another USA Pan product I love! The corners of my bars and cakes never stick and I love the squared of edges this pan creates.

These blondies can be made in one bowl! Combine wet ingredients, then mix in dry ingredients, then fold in chocolate and oats.
