When it’s raspberry season, it’s my favorite season! This raspberry lemon butter cake works great in a pie plate but you can also double the recipe and slow cook on high for a few hours too.
Imagine if raspberry lemonade and an ooey, gooey southern butter cake made a baby, and that’s what you can eat for dessert (and breakfast!) all week, when you make this cake!
