Equipment & Tools
Before you begin, gather the following equipment:
- Mixing bowls: For combining ingredients.
- Whisk: To mix the sugars and butter smoothly.
- Spatula: For folding in the flour and other ingredients.
- 9×9 inch baking pan: The perfect size for these blondies.

Step-by-Step: Gluten Free Blondies

Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). This step is crucial for ensuring even baking of your Gluten Free Blondies.
Step 2: Prepare the Baking Pan
Line your 9×9 inch baking pan with parchment paper, allowing some overhang on the sides. This will make it easier to lift the blondies out once they’re baked.
Step 3: Melt the Butter
In a medium saucepan over low heat, melt the unsalted butter. Once melted, remove from heat and let it cool slightly.
Step 4: Combine Sugars
In a large mixing bowl, combine the light brown sugar and granulated sugar. Pour the melted butter over the sugars and whisk until smooth.
Step 5: Add the Eggs and Vanilla
Add the large egg, egg yolk, and vanilla extract to the sugar mixture. Whisk until fully incorporated and the mixture is glossy.
Step 6: Mix the Dry Ingredients
In a separate bowl, whisk together the gluten free flour, cornstarch, baking powder, and salt.
Step 7: Combine Wet and Dry Ingredients
Gradually add the dry mixture to the wet mixture, stirring until just combined. Be careful not to overmix!
Step 8: Fold in the Goodies
Gently fold in the white chocolate chips and toasted walnuts until evenly distributed throughout the batter.
Step 9: Bake
Pour the blondie batter into the prepared baking pan, smoothing the top with a spatula. Bake in the preheated oven for 25-30 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out with a few moist crumbs.
Step 10: Cool and Cut
Once done, remove the blondies from the oven and let them cool completely in the pan on a wire rack. Once cooled, lift them out using the parchment overhang and cut into squares.
Customize for Your Needs

Feel free to personalize your Gluten Free Blondies with these variations:
- Substitute the white chocolate chips with dark chocolate or milk chocolate chips for a different flavor.
- Add dried fruit like cranberries or cherries for a fruity twist.
- Use pecans or almonds in place of walnuts for a different nutty flavor.
- For a spiced version, add a pinch of cinnamon or nutmeg to the dry ingredients.
Chef’s Notes
