If i want to use a glaze or frosting on muffins do just up the sugar recipe?

You don't need to up the sugar in the muffin recipe itself if you're planning to add a glaze or frosting. Here's why:

* Glaze/Frosting Adds Sugar: The glaze or frosting will already provide the extra sweetness you desire.

* Potential for Over-Sweetness: Increasing the sugar in the muffins could result in overly sweet muffins, especially when paired with a sweet glaze or frosting.

* Balance of Flavors: The added sweetness from the glaze/frosting can help balance out the richness of the muffins, creating a more harmonious flavor profile.

Instead of adding more sugar to the muffin recipe, consider these options:

* Use a less sweet glaze or frosting: You can find recipes for glazes and frostings that are less sweet, or adjust the sugar content yourself.

* Use a drizzle instead of a full coating: A light drizzle of glaze or frosting can add a touch of sweetness without being overwhelming.

* Focus on other flavors: Instead of relying on sweetness, explore other flavor additions to your muffins, such as spices, extracts, or fruit.

Remember, the goal is to create a delicious and balanced muffin, and adding extra sugar might not always be the best approach.
