Tips & Substitutions

For a lighter version, consider substituting half of the vegetable oil with unsweetened applesauce. If you prefer a nutty flavor, adding chopped walnuts or pecans to the cereal mixture can enhance the taste. Ensure the Grape-Nuts flakes are lightly crushed to achieve the right texture in the cake. You can also experiment with different spices, like nutmeg, for a unique twist.

Serving Suggestions

This crunchy cinnamon coffee cake is delightful when served warm, drizzled with the glaze. It pairs beautifully with a cup of coffee or tea, making it an ideal breakfast treat or afternoon snack. For a festive twist, serve with Fresh Apples With Caramel Sauce as a side dish for a sweet contrast.

Storage & Reheating

Store leftover coffee cake in an airtight container at room temperature for up to three days. For longer storage, refrigerate it for up to a week. To reheat, simply microwave individual slices for about 20 seconds or warm in the oven at 350°F for 10-15 minutes until heated through.
