What Kind of Oats Should I Use?

For this cake, old-fashioned rolled oats work best. Quick oats can be used in a pinch, but they will soften more and give a slightly mushier texture. Avoid steel-cut oats entirely—they won’t soften enough and will affect the cake’s tender crumb.

If you want to boost texture, a sprinkle of extra oats on top before baking can add a subtle bite and a rustic look.

How To Make the Lazy Day Oatmeal Cake

Step 1: Soak the Oats

Pour boiling water over the oats in a bowl. Let them sit for 20 minutes until fully softened. This step is key to the cake’s signature texture.

Step 2: Mix the Batter

Combine the softened oats with both sugars, melted butter, eggs, and vanilla. Mix until smooth. Then, stir in the flour, baking soda, spices, and salt until just combined.

Step 3: Bake the Cake

Pour the batter into a greased 9×13-inch baking pan. Bake at 350°F (175°C) for 30–35 minutes or until a toothpick comes out clean from the center.

Step 4: Prepare the Glaze

While the cake bakes, stir together butter, brown sugar, evaporated milk, and shredded coconut in a saucepan. Cook until bubbling.

Step 5: Broil the Topping

Once the cake is done, pour the warm glaze over it. Place the cake under the broiler for a few minutes to toast the top until golden and bubbling.

How to Serve and Store Lazy Day Oatmeal Cake

This cake is best served warm when the topping is gooey and the crumb is soft—but it’s just as good cold the next day. You can refrigerate leftovers in an airtight container for up to 5 days. Reheat slices briefly in the microwave for that fresh-out-of-the-oven feel.

This recipe serves 12 generous pieces, making it perfect for gatherings, brunches, or meal prep for sweet treats during the week.
