Breakfast Cake

A breakfast cake and other similar treats always seem to make mornings feel special.

I’m not a big breakfast eater so by mid morning, I’m usually in the mood for something subtly sweet, satisfying and the ideal accompaniment to my freshly poured cup of coffee. This is the time when a mini orange oatmeal cake seems to come in handy.

How To Make Oatmeal Cake

  1. An oatmeal cake is made by combining old-fashioned rolled oats with a splash of orange juice in a small saucepan. As the orange juice and oats simmer, the oats become soft. You’re basically cooking the oats in orange juice instead of the traditional way of cooking them in water.
  2. After the oats have softened and cooked, remove the pan from the heat and set it aside to cool. Meanwhile, whisk together flour, sugar, and baking soda in a medium sized bowl.
  3. In a separate small bowl, whisk together melted butter, an egg and a touch of vanilla.
  4. Combine the wet ingredients with the dry ingredients and pour into a small baking dish. The oat cake bakes at 350 degrees F for about 25 minutes.

Best Baking Dish For Mini Cakes

For this oatmeal cake, I use a 5-inch square baking dish. A 5 inch by 5 inch baking pan has an area of 25 square inches.  If you have a 4 inch by 6 inch baking pan, it has an area of 24 square inches (4 inches x 6 inches) and should work just fine.  Also if you have a 5 – 6 inch diameter baking dish, that should work as well.

For best results, use a dish of similar size. You can also use this cake batter to make 2 muffins in a muffin pan or you can bake 2 smaller mini cakes in oven safe ramekins.

  1. Simply delicious! I did add orange zest to the batter to bring out the orange flavor a bit more. Love these amazing small portion recipes.

    Made this during my isolation due to the Coronavirus, I only had one fresh orange so I squeezed that and added lemon juice to make the 1/2 cup and to cut calories I used Truvia instead of sugar. It came out delicious. So light and tasty. I will be making this again!

    1. I’m so happy you enjoyed the cake. Thank you for sharing the changes you made to the recipe – I know it will help other readers who might want to make it.

    I absolutely loved this beautiful, tender, mini orange oat breakfast cake! It was perfect. Just lightly sweet and so satisfying! I enjoyed mine with a nice cold glass of milk, but when my friend came over to visit she enjoyed her piece with a mug of hot tea.

    I made this and it was fantastic!!!!! However was sure I had orange juice, wrong, what to do, searched and I found margarita mix. It had orange, lemon and lime so I figured can’t be all bad. This is a very moist cake perfect for one or two. Will make it often, thank you.
