Now, onto the exciting part – let’s get baking!

Preheat your oven to 350°F and grease and flour a 9-inch square baking pan.

Preparing the Oatmeal Ingredients

Begin by combining 1 cup of old-fashioned rolled oats, 1/2 cup of quick cooking oats, 1/4 cup of oat flour (made by blending oats in a food processor), 1 teaspoon of baking powder, 1 teaspoon of cinnamon, and 1/2 teaspoon of nutmeg in a medium-sized mixing bowl. Mix all ingredients together thoroughly.

Preparing the Streusel Topping

We can’t forget about the streusel topping! In a small bowl, combine 1/2 cup of chopped walnuts, 1/2 cup of shredded coconut, 1/4 cup of brown sugar, and 1 teaspoon of cinnamon. Stir well.

Mixing Wet Ingredients

In a separate larger mixing bowl on high speed or with an electric mixer, cream together 3/4 cup of white sugar, 1/2 cup (1 stick) of unsalted butter, and 1/4 cup margarine (or more butter) until light and fluffy. Then add 2 eggs beaten slightly with a fork and mix until fully combined before adding in 1 tsp. vanilla extract.

Combining the dry and wet ingredients

Slowly add the dry oat mixture to the wet ingredients in parts while alternating between adding 3 cups all-purpose flour along with some milk (about 3 tablespoons) to help moisten the dense mixture. Mix thoroughly after each addition.

Adding water to mixture

Once all dry ingredients have been incorporated into wet ingredients, stir in 1/4 cup boiling water until fully combined.

Baking the Oatmeal Coffee Cake

Next up is assembling everything we’ve made. Spread half of your oatmeal batter evenly into the prepared baking pan and sprinkle half of the streusel over it. Then, add another layer of oatmeal batter on top, followed by the remaining streusel mixture.

Bake for 40 to 50 minutes, or until a toothpick inserted into the center of the cake comes out clean. Allow to cool in the pan for at least 10 minutes before slicing and serving!

Now that you have successfully prepared a delicious Oatmeal Coffee Cake, you can feel free to experiment with your own substitutions and variations mentioned in section (5)!

Are you looking to switch things up with this oatmeal coffee cake recipe? No worries, I’ve got some great suggestions to try out.

Firstly, if you’re not a fan of walnuts or coconut, feel free to leave them out entirely. This recipe is very versatile, so don’t be afraid to customize it to your liking.

If you’re looking to make this recipe vegan-friendly, you can easily substitute the milk and eggs with non-dairy alternatives such as almond milk and flax eggs. For the butter or margarine, choose a plant-based brand that works well for baking.

Another variation you can try is adding sliced apples on top of the crumb topping for an apple oatmeal coffee cake. Or, add a handful of blueberries or mashed bananas into the batter for some additional fruity flavor.

For those who love cinnamon, you can sprinkle additional amounts throughout the cake batter and in the crumb topping for a more pronounced cinnamon flavor. Nutmeg also pairs well with cinnamon and can be added in small amounts.

If you prefer a gluten-free version of this coffee cake, swap out the all-purpose flour for oat flour. Additionally, you can replace rolled oats with quick cooking oats or even baked oatmeal.

Finally, if you’re looking for a more savory twist to this recipe, consider adding in some streusel toppings such as pecans or swapping out some of the sweet ingredients for sour cream to create a tangier flavor profile.

Whichever variation or substitution you choose to make, just keep in mind not to adjust the baking soda and powder ratios as they play a crucial role in ensuring that the cake rises properly. Have fun experimenting!

Once the oatmeal coffee cake has cooled to room temperature, you can store it in an airtight container or wrap it tightly with plastic wrap. You can also freeze for up to 3 months. Before serving, defrost at room temperature for several hours.

You can make this baked oatmeal coffee cake ahead of time by preparing the batter and refrigerating it overnight. In the morning, add the toppings and bake as directed. It may take a few extra minutes to bake if it’s chilled.

If you have leftover oatmeal coffee cake, keep it fresh by storing in the refrigerator for up to 3 days. Simply warm each slice in the microwave for a few seconds before serving.

Reheating this coffee cake is a breeze! Preheat your oven to 350°F (175°C) and place the sliced pieces on a baking sheet lined with parchment paper. Bake for about 10-12 minutes or until heated through.

To enhance the flavor of your oatmeal coffee cake, try adding a scoop of vanilla ice cream, whipped cream or drizzling caramel sauce on top. This will give it a delicious and creamy flavor profile that pairs perfectly with warm comforting mornings or cool cozy evenings.

Tips for Perfect Results

There are a few tips that I think can make a great difference in the outcome of this oatmeal coffee cake recipe. Here are some tips to follow to ensure perfect results.

First and foremost, when measuring dry ingredients, be sure to spoon the flour into the measuring cup and level it off with a straight edge. Packing too much flour into the measuring cup will result in a denser cake.

Secondly, make sure that all your ingredients are at room temperature. The butter should be soft enough to cream easily but not melted, as this may affect the texture of the cake.

Furthermore, do not overmix the batter as it can result in a tough cake. Mix just until all the ingredients are incorporated and there are no lumps.

Also, when making the streusel topping, use cold butter or margarine and blend it with a pastry cutter or fork until crumbly. This will help achieve that perfect crumbly streusel topping.

Lastly, allow the cake to cool in the pan for at least 10 minutes before removing it onto a wire rack to cool completely. This allows for the cake to set, making it easier to handle and prevents it from breaking apart.

By following these tips, you can ensure that your oatmeal coffee cake will come out perfectly every time!

Bottom Line

In conclusion, the Oatmeal Coffee Cake recipe is a delicious and satisfying way to start your day or serve as a dessert for special occasions. With simple ingredients like oats, brown sugar, cinnamon, and egg, you can easily whip up a batch of this flavorful cake in no time.

If you’re looking to switch things up, there are plenty of substitutions and variations you can try. For instance, swap out the walnuts for pecans or add some blueberries for a fruity twist. And don’t forget to pair your cake with a warm cup of coffee or milk for the ultimate indulgence.

By following our tips for perfect results and storing leftovers properly, you can enjoy this tasty treat for days to come. So why not give it a try and impress your friends and family with your baking skills? Trust me, they’ll be begging for seconds!
