I've been trying to make confetti cake by making white or yellow cake with rainbow sprinkles, but the sprinkles sink to the bottom. Is there a way to get them to stay in the middle?

You had me curious so I did my normal extensive search. This is what I found:
"The secret is to coat the sprinkles with flour before mixing them into the batter. This way, it is easier for them to stay suspended in the cake batter, and not just sink to the bottom. (the same tip goes for placing chocolate chips in brownie batter. Coat them with cocoa powder to bake your best brownie)"

Thank you!

Add the sprinkles into the batter last and stir with a spoon
