Step-by-Step Instructions (Perfect Every Time)

Step 1: Preheat & Prep

Preheat oven to 350°F.
Grease 9×13 pan and line with parchment (for easy removal).

Step 2: Cream Butter & Sugar

Beat butter + sugar until very light and fluffy (3–4 minutes).
This is your cake’s tenderness insurance.

Step 3: Add Eggs & Vanilla

Add eggs one at a time, beating well after each.
Scrape bowl, add vanilla.

Step 4: Dry Ingredients

Whisk flour, baking powder, salt in separate bowl.

Step 5: Alternate Wet & Dry

Add dry ingredients in 3 additions, alternating with milk in 2 additions.
Mix until just combined — some lumps are fine.

Step 6: The Sprinkle Magic

Gently fold in jimmies with spatula — don’t overmix or colors bleed.

Step 7: Bake to Perfection

Pour into prepared pan, smooth top.
Bake 35–40 minutes until golden and toothpick has moist crumbs.

Step 8: Cool & Finish

Cool in pan 15 minutes, then transfer to rack.
Dust generously with powdered sugar just before serving (it dissolves if done too early).
