Ingredients:
- 1 ½ cups rolled oats (not instant)
- 1 ½ cups boiling water
- 1 cup (2 sticks) unsalted butter, softened
- 1 cup granulated sugar
- 1 cup packed light brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 ½ cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon ground cinnamon
- ¼ teaspoon ground nutmeg
- ¼ teaspoon salt
- Optional: ½ cup chopped walnuts or pecans
Preparing the Oatmeal Mixture:
Okay, let’s get started! The first thing we need to do is prepare the oatmeal. This step is crucial because it allows the oats to soften and become wonderfully moist, which contributes to the cake’s amazing texture.
- Combine Oats and Boiling Water: In a medium-sized bowl, pour the 1 ½ cups of rolled oats. Make sure you’re using rolled oats, not instant oats, as instant oats will become too mushy. Then, carefully pour the 1 ½ cups of boiling water over the oats.
- Let it Sit: Give the oats a quick stir to ensure they’re all submerged in the water. Now, cover the bowl with plastic wrap or a clean kitchen towel and let it sit for at least 20 minutes. This allows the oats to absorb the water and soften. You can even let it sit for longer, up to an hour, if you have the time. The longer it sits, the moister your cake will be!
Creaming Butter and Sugar:
While the oats are soaking, we can move on to creaming the butter and sugar. This is another important step because it incorporates air into the batter, which helps the cake rise and become light and fluffy.
- Soften the Butter: Make sure your butter is softened to room temperature. This is essential for proper creaming. If you forgot to take it out of the fridge ahead of time, you can microwave it in 5-second intervals, checking frequently, until it’s soft but not melted.
- Cream Butter and Sugars: In a large mixing bowl (or the bowl of your stand mixer), combine the softened butter, granulated sugar, and packed light brown sugar. Use an electric mixer (either a stand mixer or a hand mixer) to cream the butter and sugars together until they are light and fluffy. This usually takes about 3-5 minutes. Scrape down the sides of the bowl occasionally to ensure everything is evenly mixed. The mixture should be noticeably lighter in color and have a smooth, creamy texture.
Adding Eggs and Vanilla:
Now, let’s add the eggs and vanilla extract. The eggs provide structure and richness to the cake, while the vanilla extract enhances the flavor.
- Add Eggs One at a Time: Add the eggs one at a time to the creamed butter and sugar mixture, beating well after each addition. This ensures that each egg is fully incorporated into the batter.
- Add Vanilla Extract: Stir in the vanilla extract until it’s evenly distributed throughout the batter.
Combining Wet and Dry Ingredients:
It’s time to bring everything together! We’ll gradually add the dry ingredients to the wet ingredients, being careful not to overmix.
- Prepare Dry Ingredients: In a separate medium-sized bowl, whisk together the all-purpose flour, baking soda, ground cinnamon, ground nutmeg, and salt. Whisking ensures that the baking soda and spices are evenly distributed throughout the flour.
- Add Oatmeal Mixture: Add the soaked oatmeal mixture to the creamed butter and sugar mixture. Mix until just combined. Don’t overmix at this stage.
- Gradually Add Dry Ingredients: Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix, as this can develop the gluten in the flour and result in a tough cake. Mix until the flour is just incorporated and no streaks of flour remain.
- Add Nuts (Optional): If you’re using nuts, gently fold them into the batter until they’re evenly distributed.
Baking the Cake:
Almost there! Now it’s time to bake our delicious oatmeal cake.
- Preheat Oven: Preheat your oven to 350°F (175°C).
- Prepare Baking Pan: Grease and flour a 9×13 inch baking pan. You can also use baking spray with flour. This will prevent the cake from sticking to the pan.
- Pour Batter into Pan: Pour the batter into the prepared baking pan and spread it evenly.
- Bake: Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean or with just a few moist crumbs attached. The cake should be golden brown on top and spring back lightly when touched.
- Cool: Let the cake cool in the pan for 10-15 minutes before inverting it onto a wire rack to cool completely.
Serving and Storing:
Finally, the best part enjoying your homemade Rustic Oatmeal Cake!
- Serve: Serve the cake warm or at room temperature. It’s delicious on its own, but you can also top it with a dollop of whipped cream, a scoop of vanilla ice cream, or a drizzle of caramel sauce.
- Store: Store leftover cake in an airtight container at room temperature for up to 3 days. You can also freeze the cake for longer storage. Wrap it tightly in plastic wrap and then in aluminum foil before freezing. Let it thaw completely at room temperature before serving.
Tips for Success:
- Don’t Overmix: Overmixing the batter can result in a tough cake. Mix the dry ingredients into the wet ingredients until just combined.
- Use Room Temperature Ingredients: Using room temperature butter and eggs helps the batter come together smoothly and evenly.
- Check for Doneness: Use a wooden skewer to check for doneness. If the skewer comes out clean or with just a few moist crumbs attached, the cake is done.
- Let it Cool: Let the cake cool completely before frosting or serving. This will prevent the frosting from melting and the cake from crumbling.
Variations:
- Add Fruit: Add ½ cup of chopped dried fruit, such as raisins, cranberries, or apricots, to the batter for added flavor and texture.
- Add Chocolate Chips: Add ½ cup of chocolate chips to the batter for a chocolatey twist.
- Make it Gluten-Free: Substitute the all-purpose flour with a gluten-free all-purpose flour blend.
- Add a Glaze: Drizzle a simple glaze over the cooled cake. To make a glaze, whisk together 1 cup of powdered sugar with 2-3 tablespoons of milk or lemon juice until smooth.
