Can you bake with powdered sugar mixed granulated for banana bread?

While it's possible to use a mixture of powdered sugar and granulated sugar in baking, it's generally not recommended for recipes like banana bread. Here are a few reasons why:

1. Different Properties: Powdered sugar and granulated sugar have different physical properties. Powdered sugar is made from granulated sugar that has been finely ground and combined with a small amount of cornstarch to prevent caking. Due to its finer texture, powdered sugar dissolves more quickly and easily than granulated sugar.

2. Impact on Texture: In baking, the type and amount of sugar used can affect the texture of the final product. Granulated sugar provides structure and contributes to the chewy texture of banana bread. Substituting a significant portion of granulated sugar with powdered sugar can result in a denser, less fluffy bread.

3. Sweetness Level: Powdered sugar has a finer consistency and tends to be sweeter than granulated sugar due to its increased surface area. If you use a mixture of powdered sugar and granulated sugar, you may need to adjust the overall amount of sugar in the recipe to avoid making the banana bread too sweet.

4. Measuring Accuracy: Powdered sugar is typically measured by volume (cups), while granulated sugar is measured by weight (grams or ounces). This difference in measurement can introduce inaccuracies when trying to combine the two sugars.

5. Mixing Issues: Powdered sugar can clump easily, especially when combined with other dry ingredients. This can lead to uneven distribution and affect the overall texture of the banana bread.

For best results, it's generally advisable to follow the recommended amounts and types of sugar specified in a banana bread recipe. Substituting or mixing sugars can alter the intended texture, flavor, and overall quality of the baked goods.
