I have excess peach jam in my refrigerator that I am not willing to waste. No way. Every time I open the refrigerator, the jam and I have a stare-down and the jam is winning. This past weekend it hit me. Jam crumb cake! You can use a full 1/2-3/4 cup of yummy jam in the recipe and I love when a solution is as delicious as this one. This crumb cake is one of my favorite desserts. It has the perfect amount of sweetness, plenty of crumb topping and can even pass for breakfast. You know what else I love about this? You don’t need a mixer and you don’t need to soften butter. Almost instant gratification.
