Decadent Oatmeal Fudge Bars Recipe
Introduction
These Decadent Oatmeal Fudge Bars combine a buttery oatmeal crust with a rich, creamy chocolate fudge filling. They’re the perfect treat for anyone craving something sweet and comforting with a delightful texture.

Ingredients
- 1 cup butter, softened to room temperature
- 2 cups brown sugar
- 2 eggs
- 2 tsp vanilla extract
- 2 1/2 cups all purpose flour
- 1 tsp baking soda
- 1 tsp salt
- 3 cups oats (old fashioned or quick)
- 2 cups semi sweet chocolate chips
- 1 14 oz can sweetened condensed milk
- 2 Tbsp butter
- 2 tsp vanilla
Instructions
- Step 1: In a large mixing bowl, cream together the softened butter and brown sugar until smooth. Add the eggs and 2 teaspoons of vanilla extract, mixing well.
- Step 2: In a separate bowl, whisk together the all-purpose flour, baking soda, salt, and oats. Gradually add this dry mixture to the butter and sugar blend, mixing until crumbly. Set aside two-thirds of this crumb mixture.
- Step 3: In a microwave-safe glass bowl, combine the chocolate chips, sweetened condensed milk, and 2 tablespoons of butter. Heat in the microwave, stirring every 30 seconds, until the mixture is smooth. Stir in the remaining 2 teaspoons of vanilla.
- Step 4: Grease a 9×13 inch baking pan. Spread the reserved two-thirds of the crumb mixture evenly across the bottom as a crust.
- Step 5: Pour and spread the chocolate fudge filling over the crust evenly.
- Step 6: Drop spoonfuls of the remaining crumb mixture over the chocolate filling, creating a rustic topping.
- Step 7: Bake in a preheated oven at 350°F (175°C) for 25 to 30 minutes, until the top is lightly golden and set.
- Step 8: Remove from the oven and allow bars to cool completely before cutting into squares.
Tips & Variations
- For a nuttier texture, add 1/2 cup chopped walnuts or pecans to the crumb mixture.
- Use dark or milk chocolate chips instead of semi-sweet for a sweeter or richer flavor.
- Chilling the crumb mixture briefly before baking can help create a firmer topping.
- For added depth, sprinkle a pinch of cinnamon into the dry ingredients.
Storage
Store the oatmeal fudge bars in an airtight container at room temperature for up to 3 days. For longer storage, keep in the refrigerator for up to one week. Reheat slightly in the microwave if desired to soften the fudge filling before serving.

FAQs
Can I use quick oats instead of old fashioned oats?
Yes, quick oats work fine and will still provide good texture, though old fashioned oats give a chewier bite.
Is it necessary to microwave the filling or can I melt it on the stove?
You can melt the chocolate chips, sweetened condensed milk, and butter in a saucepan over low heat, stirring frequently to prevent burning. Either method works well.

Ingredients
Crust and Topping
- 1 cup butter, softened to room temperature
- 2 cups brown sugar
- 2 eggs
- 2 tsp vanilla extract
- 2 1/2 cups all purpose flour
- 1 tsp baking soda
- 1 tsp salt
- 3 cups oats (old fashioned or quick)
Fudge Filling
- 2 cups semi sweet chocolate chips
- 1 14 oz can sweetened condensed milk
- 2 Tbsp butter
- 2 tsp vanilla extract
Instructions
- Prepare Crust Mixture: Cream together the softened butter and brown sugar in a large mixing bowl until smooth and fluffy. Add the eggs and vanilla extract, mixing thoroughly. In a separate bowl, whisk together the all purpose flour, baking soda, salt, and oats. Gradually add the dry ingredients to the butter mixture, mixing until crumbly but combined. Set aside.
- Make Chocolate Fudge Filling: In a microwave-safe glass bowl, combine the semi sweet chocolate chips, sweetened condensed milk, and butter. Heat in the microwave in 30-second intervals, stirring well after each, until the mixture is smooth and fully melted. Stir in the vanilla extract to enhance the flavor.
- Assemble Bars: Grease a 9×13 inch baking pan. Spread about two-thirds of the crumb mixture evenly into the bottom of the pan to form the base crust. Pour and spread the chocolate fudge filling evenly over this crust layer. Finally, drop spoonfuls of the remaining crumb mixture over the fudge filling, creating a textured topping.
- Bake: Preheat the oven to 350°F (175°C). Bake the assembled bars for 25 to 30 minutes, or until the edges are golden brown and the topping is set. Remove from oven and allow to cool completely in the pan before cutting into bars for serving.
Notes
- Use old fashioned oats for a chewier texture or quick oats for a softer bite.
- Ensure butter is softened to room temperature for easier creaming.
- Cooling completely before slicing helps the bars hold their shape better.
- Store bars in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
- For a nutty variation, add 1 cup of chopped walnuts or pecans to the crust mixture.
