Lazy Daisy Oatmeal Cake is a soft, spiced sheet cake topped with a caramelized coconut-pecan glaze. A cozy, old-fashioned dessert that never goes out of style.
Preheat the oven to 350°F and spray a 13x9-inch broiler-safe pan with nonstick spray.
Stir the boiling water and oats together in a heatproof bowl. Let sit 30 minutes, stirring occasionally, until softened.
Whisk the flour, baking soda, cinnamon, nutmeg, and salt in a medium bowl.
Beat the butter, granulated sugar, brown sugar, and vanilla in a stand mixer with the paddle attachment until fluffy, 3–4 minutes. Add eggs one at a time, mixing well.
Add the flour mixture and mix until combined, then mix in the oats until mixed; scraping the bowl as needed. Pour batter into the prepared pan.
Bake 30–35 minutes, until a tester comes out clean. Cool 10 minutes on a rack.
For the Topping
Melt the butter, brown sugar, and condensed milk in a heavy-bottomed saucepan, stirring constantly, until simmering, about 1 minute.
Remove from the heat and stir in the coconut and pecans. Spread over warm cake.
Broil on the center rack 2–3 minutes, watching closely, until bubbly and golden. Cool completely before serving.
Notes
Chef Jenn’s Tips
Make sure the oats cool completely before adding them to the batter; this keeps your cake light and fluffy.
Toast the pecans before adding them to the topping for maximum flavor. Watch the cake closely under the broiler. It can go from golden to burnt in seconds.
