Oatmeal Fudge Bars Recipe
Introduction
Oatmeal Fudge Bars are a delightful treat that combines chewy oats with rich, creamy chocolate fudge. These bars offer the perfect balance of texture and sweetness, making them an irresistible snack for any occasion.

Ingredients
- 1/2 cup unsalted butter (melted)
- 1/2 cup granulated sugar
- 1/2 cup packed brown sugar
- 1 large egg
- 2 teaspoons vanilla
- 1 cup + 2 tablespoons all-purpose flour
- 1/4 teaspoon salt
- 1/2 teaspoon cinnamon
- 1 and 1/3 cups old-fashioned oats
- 1 and 1/4 cups semi-sweet chocolate chips (or 50-70% dark chocolate)
- 1 cup sweetened condensed milk (one 14-oz can; do not use evaporated milk)
- 2 tablespoons unsalted butter
Instructions
- Step 1: Preheat the oven to 350°F (175°C). Line an 8×8 inch square baking pan with parchment paper, leaving an overhang around the edges, or line with aluminum foil and lightly grease.
- Step 2: In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar. Then whisk in the egg and vanilla extract until smooth.
- Step 3: Fold in the flour, salt, and cinnamon, followed by the old-fashioned oats until well combined.
- Step 4: Spoon about three quarters of the oatmeal mixture into the bottom of the prepared pan and spread it evenly to form the oatmeal cookie layer. Set aside the remaining mixture (about 1/2 to 3/4 cup).
- Step 5: Prepare the chocolate fudge layer by adding about 1/2 inch of water to a medium saucepan over low-medium heat. Place a large heatproof glass bowl on top of the saucepan, ensuring the bottom of the bowl does not touch the water.
- Step 6: Add the chocolate chips, sweetened condensed milk, and butter to the glass bowl. Stir gently as the mixture melts, continuing until smooth and fully combined. Remove from heat.
- Step 7: Pour the melted chocolate fudge evenly over the oatmeal cookie layer in the pan.
- Step 8: Drop spoonfuls of the reserved oatmeal mixture over the top of the fudge layer, leaving some fudge visible between the oatmeal pieces.
- Step 9: Bake in the preheated oven for 25-30 minutes, until the oatmeal pieces on top look set. For chewier bars, avoid baking longer as it will make them crispier.
- Step 10: Let the bars cool completely in the pan, about 3 hours. Use the parchment paper or foil overhang to lift the bars out of the pan and place them on a cutting board. Slice into bars with a sharp knife.
Tips & Variations
- For a richer chocolate flavor, try using dark chocolate chips between 60-70% cocoa.
- Adding a handful of chopped nuts, like walnuts or pecans, to the oatmeal mixture can add a nice crunch.
- If you prefer a softer bar, slightly underbake and allow the bars to set fully as they cool.
- Use parchment paper for easier removal of bars from the pan and cleaner slicing.
Storage
Store the oatmeal fudge bars in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week. Bars can also be frozen for up to 2 months; thaw at room temperature before serving. Reheat gently in a microwave or enjoy chilled based on your preference.

FAQs
Can I substitute quick oats for old-fashioned oats?
Quick oats can be used in a pinch but will result in a softer, less textured bar. Old-fashioned oats provide better chewiness and structure in this recipe.
What can I use if I don’t have sweetened condensed milk?
Sweetened condensed milk is key for the fudge layer’s texture and sweetness. Avoid evaporated milk, as it lacks sugar. If necessary, you can make a homemade version by simmering milk with sugar until thickened.

Ingredients
Oatmeal Cookie Layer
- 1/2 cup unsalted butter (melted)
- 1/2 cup granulated sugar
- 1/2 cup packed brown sugar
- 1 large egg
- 2 teaspoons vanilla extract
- 1 cup + 2 tablespoons all-purpose flour
- 1/4 teaspoon salt
- 1/2 teaspoon cinnamon
- 1 and 1/3 cups old-fashioned oats
Chocolate Fudge Layer
- 1 and 1/4 cups semi-sweet chocolate chips (or 50-70% dark chocolate)
- 1 cup sweetened condensed milk (one 14-oz can)
- 2 tablespoons unsalted butter
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8×8 inch square baking pan with parchment paper, leaving an overhang on the sides for easy removal, or alternatively, use lightly greased aluminum foil.
- Mix Oatmeal Cookie Batter: In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth. Add the egg and vanilla extract, whisking to combine thoroughly. Stir in the all-purpose flour, salt, and cinnamon until just incorporated. Fold in the old-fashioned oats evenly throughout the mixture.
- Create Oatmeal Cookie Base: Spoon about three-quarters of the oatmeal cookie batter into the bottom of your prepared pan, spreading evenly to form a smooth, dense layer. Set aside the remaining batter (about 1/2 to 3/4 cup) for later use.
- Prepare Chocolate Fudge: Fill a medium saucepan with about 1/2 inch of water and bring to low-medium heat. Place a large heatproof glass bowl over the saucepan, ensuring the bowl’s bottom does not touch the water (double boiler setup). Add the chocolate chips, sweetened condensed milk, and butter to the bowl, stirring gently until the mixture melts into a smooth, glossy chocolate fudge.
- Assemble Bars: Remove the chocolate fudge from heat and immediately pour it evenly over the oatmeal cookie layer in the pan. Scatter spoonfuls of the reserved oatmeal cookie mixture over the top of the fudge, leaving some fudge visible between dollops for a marbled appearance.
- Bake: Place the pan in the preheated oven and bake for 25 to 30 minutes. The oatmeal cookie pieces on top should look set but the bars will remain chewy; avoid overbaking if you prefer softer bars.
- Cool and Slice: Remove the pan from the oven and allow the bars to cool fully at room temperature for about 3 hours to set properly. Use the parchment paper or foil overhang to lift the bars out of the pan. Slice into bars with a sharp knife and serve.
Notes
- Do not substitute sweetened condensed milk with evaporated milk as it will alter the texture and sweetness of the fudge layer.
- For a richer chocolate flavor, use dark chocolate chips between 50-70% cocoa.
- Ensure the bottom of the glass bowl does not touch the boiling water during melting to prevent scorching.
- Bars can be stored in an airtight container at room temperature for up to 4 days or refrigerated for up to a week.
- For crispier bars, bake a few minutes longer but expect less chewiness.
