Get ready to indulge in homemade magic!
For the Base
- Brownie Mix – Use a 19 or 19.1 oz box for the best texture; brands like Ghirardelli or Betty Crocker work perfectly.
- Unsalted Butter (1/2 cup / 113g) – Adds richness; can be easily substituted with margarine if desired.
- Egg (1 large) – Critical for the structure; no substitutes recommended.
- Vegetable Oil (1/4 cup / 59ml) – Keeps the bars moist; melted coconut oil is a great alternative.
For the Topping
- Reese’s Peanut Butter Cups (6, chopped) – These delightful chunks create that signature flavor; feel free to add more for an extra treat!
- Peanut Butter Chips (1/2 cup / 85g) – Intensifies that iconic peanut flavor; chocolate chips can be swapped for a different taste.
- Sweetened Condensed Milk (14 oz) – Drizzle on top for a gooey goodness essential for Reese’s Bars; about 3/4 of the can is used for the perfect balance.
Step‑by‑Step Instructions for Reese’s Magic Bars
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C) to ensure it’s hot and ready for baking. Line a 9×13 inch baking dish with aluminum foil, leaving some overhang for easy removal. Lightly spray the foil with non-stick cooking spray to prevent the Reese’s Bars from sticking. Setting up your pan properly is key to achieving perfectly cooked bars!
Step 2: Mix the Brownie Base
In a large mixing bowl, combine ½ cup of softened unsalted butter, one large egg, and ¼ cup of vegetable oil. Gradually add in the brownie mix, using a spatula to blend until a thick batter forms. This should take about 2-3 minutes. Once combined, press the mixture evenly into the bottom of your prepared pan, creating a smooth, even layer that will serve as the delightful base for your Reese’s Bars.
Step 3: Add the Toppings
Sprinkle the chopped Reese’s Peanut Butter Cups evenly across the brownie base, followed by ½ cup of peanut butter chips. Make sure the toppings are distributed uniformly for a satisfying bite in every square. The contrast of creamy peanut butter and chocolate atop your base will create the rich flavors you desire in these Reese’s Bars!
Step 4: Drizzle with Sweetened Condensed Milk
Carefully drizzle about ¾ of a 14 oz can of sweetened condensed milk over the toppings, ensuring some of the brownie base remains visible for the perfect texture balance. This luscious milk will meld with the chocolate and peanut butter, creating that characteristic gooeyness. Use a spoon to spread it out if necessary, giving it a nice coating.
Step 5: Bake the Bars
Place the pan in the preheated oven and bake for 28-30 minutes. You’ll know your Reese’s Bars are done when the edges start to set and the center has a slight jiggle but appears firm. Keep an eye on them to avoid overcooking, as you want a perfectly chewy texture in the center.
Step 6: Cool and Slice
Once baked, take the pan out of the oven and allow it to cool at room temperature for about 10 minutes. Then, cover the pan with foil and refrigerate for at least an hour to firm up the layers. Once completely cooled, lift the bars out using the foil overhang and cut into squares. This step ensures clean cuts and easy serving of your delicious Reese’s Bars!

Expert Tips for Reese’s Bars
-
Right Mix Size: Ensure you use a 19 oz brownie mix for the ideal texture. Anything smaller could lead to dry, crumbly bars.
-
Butter Insights: If using margarine instead of unsalted butter, ensure it’s softened properly; otherwise, it won’t blend well into the batter.
-
Chop Smartly: Chop the Reese’s Peanut Butter Cups into uneven sizes for a delightful texture contrast throughout the bars, enhancing your Reese’s Bars experience.
-
Perfect Drizzle: Drizzle the sweetened condensed milk lightly so that it seeps down without saturating the brownie base too much. This keeps your bars from becoming overly gooey.
-
Cool Completely: Cool the bars at room temperature before refrigerating, allowing them to set properly for clean slicing.
