How to Prepare Peanut Butter Cup Dump Cake

This recipe is delightfully easy — just layer, pour, and bake.

Step-by-Step Instructions

---

Step 1 — Prepare the Baking Dish

1. Preheat oven to 350°F (175°C)

2. Grease a 9×13 baking dish with butter or non-stick spray

This prevents sticking and helps the bottom brown beautifully.

---

Step 2 — Add Peanut Butter Cups

• Spread 2 cups of peanut butter cups across the bottom

• Use mini ones or chop full-size Reese’s

This forms your decadent candy base.

---

Step 3 — Drizzle Melted Peanut Butter

• Melt ½ cup peanut butter

• Drizzle evenly on top of the peanut butter cups

This ensures every bite has peanut butter richness.

---

Step 4 — Pour the Sweetened Condensed Milk

• Slowly pour 1 can sweetened condensed milk evenly over the candy layer

This is the gooey glue that binds the magic together.
Think of it like dessert caramel cement — thick, creamy, dreamy.

---

Step 5 — Add Chocolate Chips (Optional)

If you want a double chocolate hit:

• Sprinkle ½ cup chocolate chips

They soften and melt into the filling as it bakes.

---

Step 6 — Sprinkle Cake Mix Over Top

• Pour the dry cake mix evenly across the dish

• Do not stir

Dump cakes work by letting the layers bake naturally — resist the urge to mix.

---

Step 7 — Add Melted Butter

• Slowly pour 1 cup melted butter over the cake mix

• Again, do not stir

This creates the crumble-cake texture on top.

---

Step 8 — Bake

• Bake 40–45 minutes

• Cake topping should be golden brown and bubbling

The edges caramelize while the center stays moist and gooey.

---

Step 9 — Serve Warm

Let cool 10 minutes, then serve warm with:

• Ice cream

• Whipped cream

• Extra peanut butter drizzle

• Chocolate syrup

The contrast of warm cake and cold ice cream = heaven.

Serving Suggestions

This dessert tastes incredible both warm and chilled, making it versatile for parties or meal prep treats.

Tips for the Best Dump Cake Success

✅ Don’t Stir Anything

Dump cake magic comes from layering. Mixing ruins the gooey texture.

 Use Real Butter

Margarine won’t give the same richness or browning.

Try Different Cake Mix Flavors

 Add Salt

A sprinkle of sea salt makes the sweetness pop.

✅ Let It Rest

10 minutes cooling helps the structure set.

✅ For a Firmer Sliceable Cake

Bake 5–10 extra minutes and chill before cutting.
