Step 1: Preheat your oven to 350°F (175°C) and line an 8x8 inch baking pan with parchment paper, leaving an overhang for easy removal.
Step 2: In a small saucepan over medium heat, melt the butter and continue cooking until it turns golden brown and smells nutty. Remove from heat and let cool slightly.
Step 3: In a large mixing bowl, combine the browned butter, brown sugar, and pure maple syrup. Whisk until smooth and well combined.
Step 4: Add the egg and vanilla extract to the mixture. Whisk vigorously for about 1-2 minutes until the batter looks shiny and slightly lightened.
Step 5: Sift in the flour, baking powder, salt, and cinnamon. Use a spatula to gently fold the dry ingredients into the wet ingredients until just combined.
Step 6: Gently fold in the diced pears and the toasted pecans, ensuring they are evenly distributed throughout the maple pecan and pear blondies batter.
Step 7: Spread the batter evenly into the prepared pan. Bake for 30-35 minutes, or until the edges are golden and a toothpick inserted into the center comes out with just a few moist crumbs.
Step 8: Allow the maple pecan and pear blondies to cool completely in the pan before lifting them out and slicing into 12 squares.
