1 15.25 oz. box yellow cake mix
2 21 oz. cans cherry pie filling
1/2 C (1 stick) unsalted butter, cubed
Vanilla ice cream or whipped cream, garnish
Lightly grease crock pot with butter or nonstick spray, or use a slow cooker liner for easy clean-up.
In a large bowl, cut cubed butter into cake mix and mix until coarse and crumbly.
Pour cherry pie filling into crock pot. Cover with cake mixture.
Cook on high for 2 hours, or until cake is golden brown and cherry filling is hot and bubbly.
Serve hot, with vanilla ice cream or whipped cream.
