Ingredients List
For the Oatmeal Squares:
- 2 cups rolled oats
- 2 cups milk (or unsweetened almond milk for a dairy-free version)
- 2 eggs
- ½ cup Greek yogurt (adds protein and creaminess)
- 3 tbsp honey or maple syrup (for sweetness)
- 1 tsp vanilla extract
- 1 tsp baking powder
- 1 tsp cinnamon
- Pinch of salt
Optional Add-ins:
- ½ cup protein powder (vanilla or unflavored for extra protein)
- ¼ cup chopped nuts (such as almonds, walnuts, or pecans for crunch)
- ¼ cup raisins or berries (blueberries, raspberries, or dried cranberries)
Instructions
Step 1 — Preheat the Oven and Prepare the Baking Dish
Preheat your oven to 350°F (175°C). Grease a baking dish or line it with parchment paper for easy removal of the oatmeal squares after baking. A 9×9-inch pan works perfectly for this recipe.
Step 2 — Mix the Dry Ingredients
In a large mixing bowl, combine:
- 2 cups rolled oats
- 1 tsp baking powder
- 1 tsp cinnamon
- Pinch of salt
Mix these dry ingredients together until well distributed.
Step 3 — Whisk the Wet Ingredients
In a separate bowl, whisk together:
- 2 cups milk (or almond milk for a dairy-free option)
- 2 eggs
- ½ cup Greek yogurt
- 3 tbsp honey or maple syrup (for sweetness)
- 1 tsp vanilla extract
Whisk until the mixture is smooth and well-combined.
Step 4 — Combine Wet and Dry Ingredients
Pour the wet mixture into the dry ingredients and stir until fully combined. The batter will be slightly thick. Let the mixture sit for about 5 minutes to allow the oats to absorb some of the liquid. This will help the oatmeal squares set properly once baked.
Step 5 — Add Optional Add-ins
If you’re using any add-ins, gently fold in:
- ½ cup protein powder (for an extra protein boost)
- ¼ cup chopped nuts (for added crunch)
- ¼ cup raisins or berries (for a burst of fruity flavor)
Step 6 — Bake
Pour the batter into the prepared baking dish and spread it out evenly. Place it in the oven and bake for 35–40 minutes, or until the top is golden brown and the center is set. You can test for doneness by inserting a toothpick—if it comes out clean, the oatmeal squares are ready!
Step 7 — Cool and Slice
Allow the oatmeal squares to cool for 10 minutes before slicing into squares. This helps them set and makes them easier to cut.
Additional Notes
- Customizable Sweetness: Adjust the amount of honey or maple syrup depending on your sweetness preference. For a sugar-free option, use stevia or another sweetener of your choice.
- Texture Tips: If you prefer a firmer texture, let the oatmeal mixture sit longer before baking, or add a bit more flour or protein powder for additional structure.
- Make-Ahead: These squares are perfect for meal prepping. Simply bake them in advance, and store them in an airtight container for up to 5 days in the fridge.
