Ready to bake this Rhubarb Cake?

Here’s what you need to know before you get started!
Choosing the Best Rhubarb for Baking:

  • Whether you’re picking up the rhubarb from the supermarket or from a local farmer’s market, make sure you pick stalks that are fresh, plump, and firm when you touch them.
  • Wilted and soggy stalks are a big NO THANK YOU!
  • If you can’t find nice fresh rhubarb in the store ask your gardener friends, they’re probably happy to share!!
  • Flavor-wise, stalks that have a deeper reddish tone have a more intense flavor, BUT green rhubarb works just fine too!

Can I Make & Store this for Later?

Yes, you can! This rhubarb cake is actually an excellent dessert cum breakfast option that you can make and store for the next few days. It’s fine for 1-2 days uncovered in a cupboard. After that loosely cover it for another day or two for best results.

You can cover it in cling wrap BUT the streusel will get soggy. Just an FYI.

Tips & Tricks to make the BEST Rhubarb Coffee Cake!

Ready to make this super simple yet delicious coffee cake? Here are a few tips and tricks to keep in mind to nail the recipe:
● Looking to give it a nice twist? You can swap the streusel in the recipe and top the cake with a layer of any seasonal fruit you have in your kitchen. Peaches, strawberries, and blueberries are some excellent options that taste great when paired along with a rhubarb flavor base.
● The streusel on the top can make it harder to tell if it’s finished baking so be sure you use a cake tester and if it comes out clean, it is time to get your cake out of the oven.
● You can also sneak in some chopped walnuts or almonds into the streusel mix to lend the topping an extra element of crunch after it is done!
● Make sure you start with the butter while it is cold for the streusel crumbs to come out perfect and then refrigerate it! Softened butter will get gooey when you work it and then melt right into the cake during baking making your streusel a complete mess

Rhubarb Cake Serving Ideas & Suggestions

This summer dessert tastes incredible as is or alongside your cup of evening tea. But if you’re looking to take things up a notch, here are a few ideas to get you going.

  • Top a slice of the rhubarb cake with a scoop of vanilla ice cream
  • Lightly dust some icing sugar on the rhubarb cake before serving
  • Or top with some whipped cream or marshmallow fluff
  • You can have it for a quick breakfast the next day along with a cup of coffee
  • Serve it with this Lavender Ice Cream for a seasonal treat your won’t forget!

Do I have to bake this in a skillet?

NO! But if you want to bake in a cast-iron skillet use a 10 in for best results. Otherwise use a 9-10 inch round pan. OR use any 1 1/2 quart baking dish for best results. Using a smaller pan can cause the cake to bubble up and over the top making a huge mess in your oven!
