Ingredients

• 1 cup rolled oats
• 1.25 cups boiling water
• 0.5 cup unsalted butter
• 0.75 cup granulated sugar
• 0.75 cup light brown sugar, packed
• 2 large eggs
• 1 teaspoon vanilla extract
• 1.25 cups all-purpose flour
• 1 teaspoon baking soda
• 1 teaspoon ground cinnamon
• 0.5 teaspoon salt
• 0.5 cup light brown sugar, packed (for topping)
• 0.25 cup unsalted butter, melted (for topping)
• 0.5 cup shredded coconut (optional)
• 0.5 cup chopped pecans or walnuts

Directions

Step 1

Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking pan.

Step 2

In a small bowl, combine the rolled oats and boiling water. Stir well and let it sit for 15-20 minutes to soften.

Step 3

In a large mixing bowl, cream together the unsalted butter, granulated sugar, and light brown sugar until light and fluffy.

Step 4

Add the eggs to the sugar mixture, one at a time, beating well after each addition. Stir in the vanilla extract.

Step 5

In a medium bowl, whisk together the all-purpose flour, baking soda, ground cinnamon, and salt.

Step 6

Slowly add the dry ingredients to the wet ingredients, mixing just until combined.

Step 7

Fold in the softened oatmeal mixture until evenly incorporated.

Step 8

Pour the batter into the prepared baking pan and smooth the surface with a spatula.

Step 9

Bake in the preheated oven for 30-35 minutes or until a toothpick inserted into the center of the cake comes out clean.

Step 10

While the cake is baking, prepare the crunchy topping. In a small bowl, mix together the light brown sugar, melted butter, shredded coconut (if using), and chopped nuts.

Step 11

Remove the baked cake from the oven and turn the oven to broil on low.

Step 12

Spread the prepared topping evenly over the warm cake.

Step 13

Place the cake back into the oven under the broiler. Broil for 2-3 minutes, keeping a close eye to prevent burning, until the topping is bubbly and golden brown.

Step 14

Let the cake cool in the pan for at least 20 minutes before slicing and serving.
