How To Make An Orange Oatmeal Cake

  1. First, let’s start by simmering old-fashioned rolled oats in orange juice. This unconventional yet delightful method infuses the oats with zesty citrus flavors. Place your oats and orange juice in a small saucepan and cook until the oats have softened.
  2. Once your oat mixture is ready, take it off the heat and allow it to cool down. While it’s cooling, grab a medium-sized bowl and whisk together your dry ingredients—flour, sugar, and baking soda.
  3. Next, in a separate bowl, mix melted butter, one egg, and a dash of vanilla extract. These are your wet ingredients, and they’ll help give the cake its soft, moist texture.
  4. Now, it’s time to merge the worlds of wet and dry. Combine both mixtures and then fold in your cooled, orange-infused oatmeal. Once everything is well-incorporated, transfer the batter to a small 5×5-inch baking dish.
  5. Finally, bake your cake at 350 degrees Fahrenheit for approximately 25 minutes. And there you have it, a Mini Orange Oatmeal Cake perfect for one or two servings!

By following these easy steps, you’ll have a delicious, single serving cake that perfectly balances comforting oats with the vibrant, refreshing notes of orange.

Serving Suggestions

Who says you have to enjoy this Mini Oatmeal Cake plain? Go ahead and make your serving as unique as you are. Trust us, a little extra something can go a long way in elevating your cake experience.

  • Citrus Drizzle: Consider whipping up a quick glaze with powdered sugar and a splash of orange juice, then drizzle it over the top for added moisture and zing.
  • Ice Cream Pairing: Imagine a warm slice of this cake topped with a scoop of vanilla or coconut milk ice cream. The temperature contrast alone will send your taste buds soaring.
  • Cream Cheese Frosting: A thin layer of cream cheese frosting can add a tangy richness that complements the cake’s citrusy notes.
  • Fruit Accents: Garnish with thin orange slices, or perhaps a few strategically placed berries for color, flavor, and a little bit of nutritional boost.

Expert Tips

  • Choosing the Right Baking Dish: When it comes to size, flexibility is key. Although a 5×5-inch square dish is ideal, you can also opt for a 4×6-inch dish with an area of 24 square inches. Even a baking dish with a 5 to 6-inch diameter will do the trick. The aim is to stick to similar surface areas to ensure even cooking.
  • Muffin and Ramekin Alternatives: Don’t limit yourself to just one type of dish! The batter for this Mini Orange Oatmeal Cake is quite versatile. It can be used to make two muffins in a standard muffin pan, or if you prefer, you can split the batter into two oven-safe ramekins to make smaller cakes.
  • Accurate Flour Measurement: Measuring flour correctly is crucial for achieving the right cake texture. The best method? Spoon the flour into your measuring cup until it’s slightly heaping, then level it off with a straight-edged utensil. Avoid scooping directly from the bag as this will compact the flour, leading to imprecise measurements and a denser cake.

  1. Two tablespoons of honey mixed in with the egg is a successful sugar substitute, but most folks will want more sweetness. The texture and flavor are just delightful. Like so many other ODK goodies, this recipe is easy to pull together.
