Banana Sheet Cake with Walnut Streusel and Rum Glaze
This recipe takes the flavors of banana bread and turns them into a super-moist sheet cake. The crunchy, nutty streusel topping balances out the sweet cake, which gets finished with a boozy rum glaze for even more flavor. To make it in advance, prepare the cake up until step 4 and then glaze it day-of. The cooled cake can be covered loosely with plastic wrap at room temperature for up to 2 days.
