For the ingredient measurements and the entire recipe, be sure to scroll down to the bottom of the blog post where the recipe card is located.
- Flour & oats: All-purpose flour works best for these bars. You must use quick-cooking oats because they prevent the bars from becoming too dense and chewy.
- Leavening: Baking powder and baking soda act as leavening agents in this recipe.
- Sugar & salt: The salt in the recipe helps balance out the sweetness from the two types of sugar – granulated and brown sugar.
- Chocolate: Bars of baking chocolate work best in this recipe and give it a smooth texture.
- Butter: This fat gives the recipe richness and flavor.
- Eggs: These add stability to the filling in the bars.

- Preheat oven to 325°F. Line pan with parchment paper and cooking spray.

- Stir in melted butter to this mix.
- Save one cup of the mix to use as the topping.
- Press the rest into the pan.
- Bake for 8 minutes until light golden brown. Set aside to cool.
- In a small bowl, combine the flour, sugar and salt with a whisk.
- Put the chocolate and butter in a heat-proof bowl set over a pot of barely simmering water. Use a silicone spatula to stir the mix until completely melted. Remove from heat.
- Whisk eggs into this chocolate mix one at a time.
- Stir in flour mixture until combined. The filling will look thick.
- Pour chocolate mixture onto cooled crust from earlier. Sprinkle the remaining oat mixture onto the filling.
- Bake for 30 to 35 minutes. Edges should be set and lightly browned.
- Cool in the pan or on wire rack for 1 hour.
- Remove from pan and cut into squares.
Tips For Success
- Only have old-fashioned rolled oats on hand? Pulse the rolled oats in your food processor to help break them down for use in the recipe.
- Avoid using chocolate chips in this recipe. They don’t melt as smoothly as bars of baking chocolate.
- For extra neat slices, refrigerate the bars for 2 hours before cutting.

Ingredients
For The Crust
- 1 cup (130 g) all-purpose flour
- 1 cup (89 g) quick-cooking oats
- ¼ cup (50 g) granulated sugar
- ¾ cup (157 g) light brown sugar, packed
- ½ teaspoon baking powder
- ¼ teaspoon baking soda
- ¼ teaspoon salt
- ½ cup (113 g) unsalted butter, melted
For The Filling
- ⅔ cup (86 g) all-purpose flour
- ½ cup (105 g) light brown sugar, packed
- ¼ teaspoon salt
- 12 ounces (339 g) semi-sweet chocolate, coarsely chopped
- ¼ cup (56 g) unsalted butter, cut into pieces
- 3 large eggs, room temperature
Instructions
Make the crust
- Preheat the oven to 325°F. Line a 9×9-inch pan with parchment paper and spray lightly with cooking spray.
- In a medium mixing bowl, combine the flour, oats, both sugars, baking powder, baking soda, and salt. Stir with a whisk to combine.
- Stir in the melted butter until combined.
- Set aside 1 cup of the mixture to use for the topping. Press the remaining mixture into the bottom of the prepared pan.
- Bake for 8 minutes until light golden brown. Set aside to cool while you make the filling.
Make the filling
- In a small mixing bowl, combine the flour, sugar, and salt. Stir with a whisk to combine.
- Place chocolate and butter in a large heat-proof bowl set over a pot of barely simmering water. Stir with a silicone spatula until chocolate has melted completely. Remove from heat.
- Whisk in the eggs, one at a time. Stir in the flour mixture until combined. The mixture will resemble thick brownie batter.
- Pour over the cooled crust. Sprinkle the top with the remaining oatmeal mixture.
- Bake for 30 to 35 minutes, until the edges are set and have browned lightly. Cool in the pan on a wire rack for 1 hour.
- Remove from pan and cut into squares. For neat slices, refrigerate for 2 hours before cutting.
Notes
- Oats: quick-cooking oats are required. Old-fashioned rolled oats will leave the bars extra dense and chewy. If you don’t have quick-cooking oats, you can pulse rolled oats in a food processor to break them down some.
- Chocolate: Use bars of baking chocolate for best results. Chocolate chips don’t melt as smoothly.
- The bars will stay fresh in an airtight container in the refrigerator for up to 3 days.
- The bars also freeze well. Cool them completely the slice and wrap them individually in plastic wrap. Place the wrapped bars in a sturdy container with an airtight lid and freeze them for up to 3 months.
- Thaw them in the refrigerator overnight when you are ready to serve them. You can eat them cold or set them out to come to room temperature.
