Line your muffin tin with cupcake liners. This makes it easy to remove the cupcakes once baked.
Step 3: Mix Dry Ingredients
In a mixing bowl, whisk together:
* All-purpose flour

Set this mixture aside as you’ll combine it later with the wet ingredients.

Mix on low speed until combined.
Step 7: Combine Dry Ingredients
Slowly add the dry ingredient mixture to the wet mixture. Mix until just combined; avoid overmixing.
