Oatmeal cake with condensed milk is a delightful dessert that’s both simple and unique. It features two crumbly oat-based layers sandwiching a smooth, creamy layer of sweetened condensed milk. Lightly sweet, subtly citrusy, and irresistibly comforting, it’s perfect for anyone who loves discovering new flavors.

Ingredients
For the Dough:
- 1 ⅔ cups all-purpose flour (200 g)
- 1 ⅔ cups rolled oats (150 g)
- 10 ½ Tbsp unsalted butter (1 stick + 2 ½ Tbsp / 150 g), chilled
- ⅓ cup sugar (80 g)
- ½ tsp baking powder
- 1–2 tsp ground cinnamon
- A pinch of salt
For the Filling:
- 1 can (14 oz / 397 g) sweetened condensed milk
- Juice and finely grated zest of 1 small lemon
Optional Add-ins:
Chopped nuts (walnuts, pecans, or almonds) for extra texture
Instructions
Prepare the Dough:
In a mixing bowl, combine the flour, rolled oats, baking powder, sugar, cinnamon, and salt. Stir until well mixed.
Grate the chilled butter on a coarse grater (freezing the butter briefly makes this easier). Mix the butter into the dry ingredients until the mixture is crumbly.

Bake the Base:
Press half of the dough evenly into a greased baking dish (about 25 × 10 cm / 10 × 4 in). Bake in a preheated oven at 190 °C / 375 °F for 10–15 minutes, until lightly golden.

Prepare the Filling:
While the base bakes, combine the sweetened condensed milk with lemon juice and zest. Mix until smooth and creamy.
Assemble the Cake:
Remove the base from the oven and pour the filling evenly over it. Sprinkle the remaining dough on top and gently press it to level. Bake until the top is golden brown.



Tips:
Add chopped nuts for texture and flavor.
For a denser cake, add 1 egg to the dough.
For extra richness, dot the top with small pieces of butter before baking.
Cool and Serve:
Allow the cake to cool to room temperature, then refrigerate for 1–2 hours to set completely. This helps the cake hold its shape when cutting.

This oatmeal cake with condensed milk is indulgent yet balanced, thanks to the bright notes of lemon that cut through the sweetness. Its crumbly layers and creamy filling make it a dessert you’ll want to savor again and again.
