Step-by-Step
-
Preheat your oven to 350°F (177°C). Generously grease and lightly flour a 12×17-inch half sheet jelly roll pan and set it aside.
-
In a large bowl, cream the softened butter on medium speed for about a minute. The butter should be light and fluffy by this point.
-
Add the sugar and beat until the mixture is fluffy and pale in color.
-
Beat in the eggs and vanilla until smooth, then incorporate the yogurt until fully combined.
-
In another bowl, whisk together the flour, baking soda, and salt.
-
Pour half of the flour mixture into the creamed butter mixture, beating on low speed for 5 seconds. Then pour in half the milk, again beating on low for another 5 seconds.
-
Repeat with the remaining flour and milk, blending until combined and smooth. Be careful not to overmix to ensure the cake remains light and fluffy.
-
Gently fold in the sprinkles, bringing the festive touch to the batter.
-
Spread the cake batter evenly in the prepared pan, ensuring a thin, smooth layer.
-
Bake for 20-24 minutes, or until the top is lightly browned and a toothpick inserted in the center comes out clean.
-
Allow the cake to cool in the pan on a wire rack.
-
For the frosting, beat the butter until creamy, then add the confectioners’ sugar, milk, vanilla extract, and salt. Beat for 3 minutes until light and fluffy.
-
Adjust the frosting consistency if needed by adding a tablespoon of milk at a time.
-
Spread the frosting all over the cooled cake and top generously with additional sprinkles.
-
Slice and serve. Cover any leftovers and store them in the refrigerator for up to 5 days.
