How to Make Butter Pecan M&M Magic Bars (Step-by-Step Instructions)
1. Preheat and Prep
Preheat your oven to 350°F (175°C). Line a 9×13-inch pan with parchment paper, leaving a slight overhang on the sides for easy lifting later.
2. Make the Crust
In a bowl, mix the melted butter with graham cracker crumbs until it looks like wet sand. Press the mixture firmly and evenly into the bottom of the prepared pan to form the crust.
3. Add the Layers
Sprinkle shredded coconut evenly over the crust. Follow with chopped pecans, then butterscotch chips, chocolate chips, and M&M’s—layer by layer, like you’re building flavor.
4. Pour the Sweetened Condensed Milk
Slowly drizzle the sweetened condensed milk over the top. Try to coat the entire surface, pouring evenly to make sure it seeps into all the gaps and binds the layers together.
5. Bake
Place the pan in the preheated oven and bake for 28–32 minutes, or until the top is golden brown and bubbling around the edges.
6. Cool and Slice
Let the bars cool completely in the pan—this part is important. Then lift them out using the parchment overhang and slice into squares.
How to Serve Butter Pecan M&M Magic Bars
These bars are rich and sweet, so small squares work best:

- For Parties: Arrange on a platter with other finger desserts.
- With Coffee or Milk: They’re great with a warm drink in the afternoon.
- For Gifting: Wrap individual bars in wax paper and place in a treat box.
Storing Butter Pecan M&M Magic Bars
- At Room Temperature: Store in an airtight container for up to 5 days.
- In the Fridge: Keeps well for up to 10 days. Let them come to room temperature before serving for best texture.
- Freezer Friendly: Wrap individual bars in plastic wrap and store in a freezer-safe bag for up to 2 months. Thaw overnight in the fridge or a few hours on the counter.
Tips and Tricks for Success
- Use Parchment Paper: It makes cleanup easier and helps lift the bars out cleanly.
- Press Layers Lightly: After adding all the toppings, press them down gently with your hand or a spatula to help them set into the milk.
- Cool Completely Before Cutting: These bars need time to firm up—don’t rush it.
- For Neat Squares: Use a sharp knife and clean it between cuts.

Butter Pecan M&M Magic Bars FAQs
Can I use unsweetened coconut?
Yes, but the bars will be a bit less sweet. Stick with sweetened if you want the classic magic bar flavor.
Do I need to toast the pecans first?
Not necessary—baking in the oven will toast them naturally. But for extra depth, a quick 5-minute toast in a skillet works great.
What kind of M&M’s work best?
Classic or mini M&M’s work well. You can also try seasonal or peanut varieties, depending on your preference.
Why did my bars fall apart?
Make sure to let them cool completely before slicing. If they’re too warm, they won’t hold their shape.
