- 1 1/2 cups (255g) semi-sweet chocolate chips
Optional add-ins:
- 1/2 teaspoon cinnamon
- 1/2 cup chopped walnuts or pecans
- 1/3 cup dried cranberries or raisins
Preparation Time
- Prep time: 10 minutes

Step-by-Step Instructions
Step 1: Preheat and Prep
Preheat oven to 350°F (175°C). Line an 8×8-inch pan with parchment paper (leave overhang for easy lifting) and lightly grease.
Step 2: Mix the Wet Ingredients
In a large bowl, whisk melted butter, brown sugar, and granulated sugar until smooth. Add eggs and vanilla and whisk until well combined.
Step 3: Add Dry Ingredients
Stir in flour, baking powder, baking soda, and salt just until combined. Fold in oats.
Step 4: Add Chocolate Chips
Fold in chocolate chips (and any optional add-ins). The batter will be thick.
Step 5: Press Into Pan
Spread the batter into the prepared pan and press into an even layer. Sprinkle a few extra chocolate chips on top if you want.
Step 6: Bake
Bake for 20–25 minutes, until the edges are golden and the center is set (a toothpick should come out with a few moist crumbs).
Step 7: Cool and Slice
Cool in the pan for 30–45 minutes before lifting out and slicing into bars.

Tips for Perfect Chewy Bars
- Don’t overbake—slightly underbaked bars stay soft and chewy.
- Press the batter evenly so the bars bake uniformly.
- Let bars cool before cutting for clean slices.
- Use rolled oats for the best chewy texture (quick oats work but are softer).
- For thicker bars, use a smaller pan (7×7) and add a few extra minutes baking time.
Variations to Try
- Peanut Butter Oat Bars: Swap 2 tablespoons butter for peanut butter.
- Triple Chocolate: Add cocoa powder to the batter and use mixed chocolate chips.
- Salted Chocolate Chip: Sprinkle flaky sea salt on top before baking.
- Trail Mix Bars: Add chopped nuts, dried fruit, and coconut flakes.
- Gluten-Free: Use certified gluten-free oats and a 1:1 gluten-free flour blend.
