This Mini Orange Oatmeal Cake is a small, tender cake made with rolled oats simmered in orange juice for bright citrus flavor. Easy to make with simple ingredients, it bakes into a soft, moist cake perfect for breakfast, a snack, or a light dessert.
In a 1-quart saucepan, bring the orange juice to a simmer and stir in the oats.
Cook for about 5 minutes, stirring occasionally, until the oats soften.
Remove from heat and let the mixture cool.
In a medium bowl, whisk the flour, sugar, and baking soda.
In a separate bowl, whisk the melted butter, egg, and vanilla.
Stir the wet ingredients into the dry ingredients, then fold in the cooled oatmeal. Pour the batter into a lightly buttered 5x5 inch baking dish.
Bake for 20 to 25 minutes or until a toothpick inserted in the center comes out clean.
Cool on a wire rack.
Dust with powdered sugar if you like.
Notes
Choosing the Right Baking Dish: A 5x5 inch dish works well, but any dish with a similar surface area is fine. A 4x6 inch dish will give you the same results.
Muffin or Ramekin Options: This batter is flexible. You can bake two muffins in a standard muffin pan or divide the batter between two 10-ounce oven safe ramekins for smaller cakes.
Measure Flour Correctly: For the best texture, spoon the flour into your measuring cup and level it off. Scooping directly from the bag packs the flour and can make the cake dense.
If doubling the recipe, bake in either two 5x5-inch baking dishes or one 6x8-inch baking dish.
