What Are Baked Oatmeal Squares?
Baked oatmeal squares are a cross between a baked oatmeal and a soft granola bar. Made by mixing rolled oats with milk, eggs, and fresh or dried fruits, then baked until set, they can be sliced into handy squares or bars. They’re chewy and moist, packed with fiber, and naturally sweetened with fruit and a touch of honey or maple syrup.
These squares are far less processed than store-bought snack bars and customizable with your favorite add-ins like nuts, seeds, or spices.

How to Make Baked Oatmeal Squares
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Lightly grease or line an 8×8-inch baking dish with parchment paper for easy removal.
Step 2: Mix Dry Ingredients
In a large bowl, combine the rolled oats, baking powder, cinnamon, and salt.
Step 3: Mix Wet Ingredients
In a separate bowl, whisk together eggs, milk, honey or maple syrup, and vanilla extract until smooth.
Step 4: Combine and Fold in Fruit
Pour the wet ingredients into the dry oats mixture. Stir gently until just combined. Fold in the fresh or frozen berries and optional nuts.
Step 5: Bake
Transfer the mixture to the prepared baking dish, smoothing the top evenly. Bake for 35–40 minutes, or until the top is golden and a toothpick inserted near the center comes out clean.
Step 6: Cool and Slice
Allow the baked oatmeal to cool completely in the pan. Lift out using parchment paper and slice into squares.
