Rhubarb Skillet Cake. So tasty! The tangy stalks will be plentiful for just a few more weeks. While it is, aficionados want to eat as much of it as possible in as many ways as they can invent.

There’s something almost magical about cast iron cookware. When properly cared for, it can virtually last forever and it produces a crisp, lovely crust on whatever it cooks or bakes! It’s no wonder cast iron is so popular today. Cake in a skillet? Yes, please!

This Skillet Cake Starts With Finely Diced Rhubarb

First, toss the diced rhubarb with 2 tablespoons of sugar and 1 tablespoon of flour. This will help keep the fruit suspended in the cake batter instead of sinking to the bottom while it’s baking.

Let that sit while you mix up the buttery rich cake batter!

Let’s Make Some Skillet Cake

Spray the bottom and sides of a cast-iron skillet with non-stick cooking spray. If you are not confident that your pan is properly seasoned, line bottom of the pan with a piece of parchment paper or wax paper cut to fit. Preheat oven to 350 degrees.

A Cute Trick With Strawberries

Fresh strawberries are one of the summer’s sweetest gifts. It’s very easy to form them into a charming heart shape with a few quick cuts. Today we’ll garnish the skillet cake with these cuties but they look equally adorable over ice cream or topping a shortcake!

Use a paring knife to remove the hull with two quick cuts which will leave a v-shape at the top of the berry. Then simply cut in half lengthwise and voila! Strawberry hearts!

Now Let’s Garnish The Cake

Finally, add sliced almonds, sprinkle with coarse sugar, and then add a sprinkle of ground cardamom or nutmeg if you like! This cake is already pretty before going into the oven!

Bake For About 35 or 40 Minutes at 350 Degrees

A toothpick or cake tester should come out clean. The strawberries will bake into tasty little pockets of “jamminess.” Cut cake into wedges to serve and top with whipped cream or ice cream for a super festive treat!

The castiron skillet will produce a lovely crisp edge on the cake and it makes a showy presentation when setting on a serving table! But if you don’t have a castiron skillet, don’t despair! You can use a round 9″ or 10″ cake pan or even a casserole dish. I’m sure it would bake up just fine in an oblong pan, too.

Hint: Math is the key to substituting a cake pan size. If your arithmetic is rusty, a 10″ skillet has 78.5 square inches of surface area and a 9″ square cake pan has 81 square inches! Close enough! A 9″ x 13″ pan at 117 square inches would make the cake thinner. It might work but you’d need to watch bake time. Remember, your kitchen is your laboratory! Never stop experimenting!
