Ingredients
For the Cake:
1 cup old-fashioned rolled oats
1¼ cups boiling water
½ cup unsalted butter, softened
1 cup brown sugar (light or dark)
½ cup granulated sugar
2 large eggs
1 tsp vanilla extract
1½ cups all-purpose flour
1 tsp baking soda
½ tsp salt
1 tsp ground cinnamon
For the Topping:
6 tbsp unsalted butter
½ cup brown sugar
¼ cup milk (or heavy cream)
¾ cup shredded sweetened coconut
½ cup chopped pecans
½ tsp vanilla extract
Instructions
Preheat your oven to 350°F (175°C).
Grease a 9×13-inch baking pan or line with parchment paper.
Step 2: Soak the Oats
In a bowl, combine the oats with the boiling water.
Let them soak for 20 minutes while you prep the rest of the cake. This softens the oats and adds moisture.
Step 3: Make the Cake Batter
In a large mixing bowl, cream together softened butter, brown sugar, and granulated sugar until light and fluffy.
Beat in the eggs one at a time, then add the vanilla extract.
Stir in the soaked oats (with water) and mix until well combined.
In a separate bowl, whisk together flour, baking soda, salt, and cinnamon.
Gradually add the dry ingredients to the wet mixture and mix just until combined.
Step 4: Bake the Cake
Pour the batter into the prepared pan and spread evenly.
Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
Let the cake rest while you make the topping.
Step 5: Prepare the Topping
In a small saucepan over medium heat, melt the butter.
Stir in brown sugar, milk, shredded coconut, and chopped pecans.
Cook, stirring constantly, until the mixture is thickened and bubbly (about 3–4 minutes).
Remove from heat and stir in vanilla.
Step 6: Broil the Topping
Turn the oven to broil.
Spread the warm topping evenly over the warm cake.
Broil for 1–2 minutes until bubbly and golden—watch closely to avoid burning!
Step 7: Cool & Serve
Let the cake cool slightly before slicing.
Serve warm, at room temperature, or chilled—it’s delicious every way!
Notes
Soak the Oats – This step is key to the moist texture.
Don’t Overmix – Mix until just combined for a tender crumb.
Use Fresh Nuts – Toast pecans beforehand for even more flavor.
Watch the Broiler – The topping can go from golden to burnt quickly—keep an eye on it.
Make Ahead – This cake keeps beautifully and may be even better the next day.
