Creating amazing mayonnaise biscuits is straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, salt, and sugar (if using).
3. Add Mayonnaise: Add the mayonnaise to the dry ingredients, mixing until crumbly.
4. Incorporate Milk: Gradually pour in the milk, stirring until the dough comes together. The dough should be soft but not sticky.
5. Knead the Dough: Turn the dough out onto a floured surface and gently knead it a few times until it is smooth.
6. Roll Out the Dough: Roll the dough to about 1-inch thickness.
7. Cut the Biscuits: Use a round cutter to cut out biscuits and place them on the prepared baking sheet.
8. Bake: Bake in the preheated oven for 15-20 minutes, or until the tops are golden brown.
9. Cool: Remove the biscuits from the oven and let them cool slightly on a wire rack before serving.

These steps will ensure you create fluffy and delicious mayonnaise biscuits with ease.
