Ingredients You’ll Need

For the Oatmeal Crumb Layer

• Quick-cooking oatmeal: Forms the base of the cookie layers and gives the bars their chewy texture.
• All-purpose flour: Provides structure.
• Baking powder: Helps the oatmeal mixture bake properly.
• Salt: Balances the sweetness.
• Butter: Adds richness and a tender, buttery texture. Use room-temperature butter for easier creaming.
• Packed brown sugar: Provides sweetness and a deeper caramel-like flavor.
• Eggs: Help bind the cookie dough together. Room-temperature eggs are easier to incorporate.
• Vanilla extract: Adds warmth and enhances the flavor of the oatmeal layer.

For the Chocolate Fudge Layer

• Chocolate chips: Create the rich chocolate center.
• Sweetened condensed milk: Gives the filling its smooth, thick consistency and sweetness.
• Butter: Adds richness to the chocolate mixture.
• Chopped nuts: Optional pecans or walnuts provide extra texture.
• Vanilla extract: Rounds out the chocolate flavor.

How to Make Chocolate Revel Bars

Step 1: Prepare the Oven and Dry Ingredients

Preheat the oven to 350°F. In a medium bowl, whisk together the quick-cooking oatmeal, all-purpose flour, baking powder, and salt. Set the mixture aside while you prepare the wet ingredients.

Step 2: Make the Oatmeal Cookie Dough

In a large mixing bowl, cream the room-temperature butter and packed brown sugar until light and fluffy.

Beat in the eggs and vanilla extract until well combined. Add the dry ingredients and stir until everything is incorporated into a thick oatmeal cookie mixture.

Set the mixture aside while you prepare the chocolate filling.

Step 3: Prepare the Chocolate Fudge Filling

Combine the chocolate chips, sweetened condensed milk, and butter in a medium saucepan. Heat over low heat, stirring continuously until the chocolate melts and the mixture becomes smooth.

Remove the saucepan from the heat. Stir in the optional chopped pecans or walnuts and the vanilla extract.

Keep the heat low while melting the chocolate to help prevent scorching.

Step 4: Assemble the Bars

Grease a 9 x 13-inch baking pan.

Press half of the oatmeal mixture evenly into the bottom of the pan. Spread the chocolate fudge mixture over this base, covering it as evenly as possible.

Crumble the remaining oatmeal mixture over the chocolate layer. Distribute it across the surface so the filling is covered with small pieces of cookie dough.

Step 5: Bake Until Lightly Browned

Bake at 350°F for approximately 25 minutes, or until the oatmeal topping is lightly browned.

The chocolate layer will be soft when the bars are hot, so avoid cutting them immediately after removing the pan from the oven.

Step 6: Cool and Slice

Allow the bars to cool before cutting them into squares. Cooling helps the chocolate filling set and makes the bars easier to slice neatly.

Serve at room temperature for a delicious combination of chewy oatmeal cookie and rich chocolate fudge.

Tips for the Best Chocolate Revel Bars

• Use room-temperature ingredients. Softened butter and room-temperature eggs are easier to combine into a smooth, evenly mixed dough.
• Measure the flour carefully. Too much flour can make the oatmeal layer dry or crumbly.
• Melt the chocolate slowly. Use low heat and stir frequently for a smooth filling.
• Spread the filling evenly. An even chocolate layer helps every bar have a balanced amount of fudge.
• Don’t worry about a perfectly smooth topping. Crumbling the remaining oatmeal mixture over the chocolate creates the traditional layered appearance.
• Let the bars cool completely. This helps the filling firm up and reduces crumbling when slicing.

Easy Variations

Add Pecans or Walnuts

The recipe includes ½ cup of chopped nuts as an optional ingredient. Pecans add a buttery crunch, while walnuts bring a slightly earthy flavor.

Choose Your Chocolate Chips

Semi-sweet chocolate chips provide a balanced chocolate flavor, while milk chocolate chips create a sweeter filling. The final sweetness will depend on the chocolate you choose.

Cut Different-Sized Squares

Cut the cooled dessert into smaller squares for dessert platters or larger bars for a more substantial treat. The supplied recipe lists 36 bars.

How to Store Chocolate Revel Bars

Room temperature: Store the bars tightly covered at room temperature for several days, as specified in the original recipe. Keep them in a cool, dry place away from direct sunlight.

Freezer: Freeze the bars for up to several weeks. For easier serving, separate layers with baking parchment inside a freezer-safe container.

Thawing: Let frozen bars thaw before serving. Allow them to come to room temperature for the best cookie texture and chocolate flavor.

Make-ahead tip: These bars are convenient to prepare ahead for gatherings because they need time to cool and set before slicing. Bake them in advance, then store them covered until you’re ready to serve.
