Ingredients
- 2 large eggs

- 2 medium carrots, finely shredded

Expert Tips / Pro Tips
To get the best results with this Easy Oatmeal Carrot Cake Recipe, make sure your butter is truly at room temperature so it blends smoothly into the oat mixture. If you prefer a more textured cake, you can skip the blending step for the oats, though the texture will be heartier and less “cake-like.” For the frosting, always use full-fat, block-style cream cheese rather than the whipped or tub varieties to ensure the topping has enough stability to hold its shape.
This recipe is very flexible based on your dietary needs or what you have in your pantry. If you want to make this cake dairy-free, you can easily swap the butter for melted coconut oil. To make it strictly gluten-free, ensure you are using certified gluten-free oats. If you don’t have honey on hand, maple syrup is an excellent natural liquid sweetener substitute. You can also add a handful of raisins or shredded coconut to the batter along with the carrots for extra flavor and texture.
Serving Suggestions
This cake is wonderful on its own, but it truly shines when topped with a simple cream cheese frosting made by mixing 8 oz of softened cream cheese with 2-3 tablespoons of honey. For a fun twist, especially for kids, you can use an ice cream scooper to form the cake into “carrot cake balls.” Roll these balls in crushed walnuts or shredded coconut for a bite-sized treat that is perfect for lunchboxes. It also pairs beautifully with a warm cup of tea or coffee.
Store any leftover carrot cake in an airtight container in the refrigerator for up to 5 days. Because of the fresh carrots and lack of preservatives, keeping it cool is essential for freshness. If you wish to freeze the cake, wrap individual slices tightly in plastic wrap and store them in a freezer-safe bag for up to 3 months. To reheat, simply let a slice thaw in the refrigerator overnight or warm it briefly in the microwave for 10-15 seconds.
