Humphrey's Triple Cinnamon Oatmeal Blondies
These chewy oatmeal blondies pack a triple punch of cinnamon flavor from ground cinnamon, cinnamon extract, and cinnamon chips. The combination of brown sugar and butter creates a rich, caramelized base while quick oats add texture and heartiness. Toffee bits provide delightful pockets of buttery crunch throughout. Perfect for potlucks, bake sales, or when you want a comforting dessert that's easier than cookies but more interesting than plain bars. The dense, sticky batter bakes into golden bars with slightly crisp edges and a tender center.

Tips
Make your own quick oats by pulsing rolled oats in a food processor for a few seconds if you don't have them on hand.
The dough will be sticky and dense - this is normal. Use wet hands or a spatula to press it evenly into the pan.
Don't overbake - the bars should still look slightly underdone in the center when you remove them as they'll continue cooking while cooling.

FAQ
Can I use regular oats instead of quick oats?
Yes, but pulse them in a food processor first or the texture will be chewier and the oats more prominent.
What if I don't have cinnamon extract?
You can omit it and increase vanilla extract to 2.5 teaspoons, though you'll lose some cinnamon intensity.
How long do these keep?
Store covered at room temperature for up to 5 days or refrigerate for up to 1 week for best quality.
