Cake Batter Shake

"Make a creamy and delicious Cake Batter Shake just like at Sonic! You can make one in just 5 minutes using ice cream, milk and your favorite cake mix. Perfect for a birthday party or a sweet treat in summer! Ever since Sonic launched their yellow cake batter shake last year and updated to the brownie batter shake more recently. This DIY version is just as good, plus it’s easy to make with just 3 simple ingredients. "
