Cake Dessert

Apple Crumb Cake with Salted Caramel Sauce


This cake requires a bit of work but the effort was well worth it. Of course, you can skip making your own caramel sauce, and use a store-bought one. But you know it’s going to be different. There’s actually 3 recipes in this post. Streusel, salted caramel sauce, and a cake recipe. You can use the streusel recipe to top any coffee cake or muffins for that crumbly edge. 

The salted caramel sauce needs no introduction. It goes amazingly well with any and every dessert! Salted caramel is another one of my kryptonite. I can go in spoonful after spoonful if I’m out of control. I tend to find quick ways to get rid of it. Either by using it for other bake products or giving it away to friends and family. I’m not sure how strong my will power is to keep myself away from that delicious thang if I know it’s still in the house. 

So anyway, the sour cream and the apples keeps the cake nice and moist. The streusel gives it a contrasting texture, and the sauce hits all the right notes. There’s a lot going on, in this cake. And I’m certain that you’ll enjoy it as much as I did.

        thanks for your reply…oh, one more thing… if i serve this cake a day after i bake it, will the crumble become soggy? reason why i asked this is because, i made a similar crumble some time back and it was crispy when it was freshly baked but the next morning, it became soft and soggy…

          I really can’t recall, but nobody complained of any soggy crumbles. To be honest, almost all the crumbles recipes will turn soft and soggy the next day due to moisture from condensation while cooling and from the cake itself. The best way to re-crisp them is to bring the cake to room temp, and bake it for 10-15 minutes for the top to crisp up again.
