Tips & Substitutions

If you don't have buttermilk, substitute with milk mixed with a tablespoon of vinegar. Always taste your fruit mixture before adding more sugar, especially if using frozen strawberries.

Serving Suggestions

This Strawberry Rhubarb Coffee Cake is delightful on its own but can be served with whipped cream or a scoop of vanilla ice cream for extra indulgence. Pair it with a hot cup of coffee or tea for a perfect afternoon treat. It also pairs beautifully with Frosty for a refreshing dessert experience.

Storage & Reheating

Store any leftover coffee cake in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate it for up to a week. Reheat individual slices in the microwave for about 15-20 seconds or in the oven at 350°F for 10 minutes until warmed through.

Frequently Asked Questions

Can I use frozen rhubarb instead of fresh?

Yes, you can use frozen rhubarb in this recipe. Just make sure to thaw it and drain any excess liquid before using it in the fruit mixture. This will help prevent the cake from becoming too soggy.

How do I know when the coffee cake is done baking?

The coffee cake is done when a toothpick inserted into the center comes out clean or with only a few moist crumbs. Be careful not to overbake, as this can make the cake dry.

Can I make this coffee cake ahead of time?

Absolutely! You can prepare the cake a day in advance and store it covered at room temperature. Just reheat slices before serving for the best taste and texture. This makes it a great option for brunch or gatherings.
