# Expert Advice:
01 -
- This cake bakes up incredibly moist and tender thanks to the combination of oil and butter
- The sprinkles stay colorful and dont bleed into the batter when you use jimmies
- One batch feeds a crowd generously so theres always enough to share
02 -
- Room temperature ingredients prevent curdling and help everything emulsify into a smooth batter
- Jimmies are the only sprinkles that hold their color in the batter. Nonpareils will bleed gray streaks.
- Completely cool cakes before frosting. Even slight warmth will cause the buttercream to slide right off.
03 -
- Weigh your flour instead of scooping. Too much flour makes a heavy dry cake.
- Sift powdered sugar directly into your mixing bowl to avoid dust storms in your kitchen.
