It's officially springtime in Minnesota! The rhubarb is ready! Us Minnesotans can't get enough of rhubarb this time of year, so I will be posting a few new rhubarb recipes within the next couple weeks.

We just got home from a wonderful 3 day weekend in Mankato at my sister's house. It was their city wide garage sales, plus we made some great food and tried out some wine at Wine Cafe! 

We tried out a bottle of Fox Run wine from Morgan Creek Vineyards, which tastes just like concord grapes. Delicious! If you're in MN, check out your local liquor store and try it out.

Back to the recipe.... this old fashioned rhubarb coffee cake is something fantastic! I found this recipe in an old church cookbook.

The cake is moist, and the topping with nuts and brown sugar is wonderful. What makes it even better, is the homemade icing that tops it all off. 

Make sure you have some friends or family around to help you eat this cake because it's so easy to want to devour it all yourself!

If you love rhubarb, then you'll want to try these Brown Sugar Rhubarb Cookies or this Rhubarb Magic Crust Custard Pie!

You can add or substitute with these ingredients:

• use brown sugar instead of granulated sugar for the icing
• add some diced fresh strawberries in the batter
• use almond extract instead of vanilla

Recipe tips:

• If you don't have buttermilk, make your own! Add one tablespoon vinegar or lemon juice to a liquid measuring cup. Add milk until you reach the one cup mark. Stir, let set for 5 minutes, then use!

• Refrigerate leftovers in an airtight container for up to five days.
