Key Things You’ll Need
- For The Bottom: - All-purpose flour: 2 cups (240g), kept at 70°F (21°C) - Fine sea salt: ½ teaspoon (3g) - Unsalted butter: 1 cup (227g), melted to 165°F (74°C) - Dark brown sugar: 1 cup (200g), packed with 3–4% moisture
- Making The Caramel: - Granulated sugar: 1 cup (200g), pure cane - Sweetened condensed milk: 14 oz (397g), room temp at 70°F (21°C) - Unsalted butter: ½ cup (113g), softened to 65°F (18°C) - Light corn syrup: ½ cup (120ml), nice and clear Heat caramel until 240°F (116°C) for a soft, stretchy pull
- For The Crunchy Top: - Butterfinger bars: 2 cups (200g), smashed into chunks about a quarter-inch big Let the topping chill around 65°F (18°C) so it grabs on well
How To Pull It All Together
- Get Your Space Ready
- Start by heating your oven to 350°F (175°C) and double-check with another thermometer if you can. Set your rack in the middle. Grab a 9x13 pan, cover it with parchment, and leave a couple-inch edge you can grab later.
- Build The Bottom Layer
- Stir together your melted butter with brown sugar, then slowly add in the flour until it looks like damp sand. Press it hard into your pan so you get about a quarter inch thick everywhere. Slide it into the oven and bake around 10–12 minutes, aiming for light golden color (think Pantone 7508 C).
- Create The Caramel
- Dump all the caramel stuff in a heavy pot, and set it over medium (about 325°F/163°C). Keep stirring nonstop. You’ll hit thread stage at 230°F (110°C), and not much later, it'll reach that soft-ball stage at 240°F (116°C). You’re looking for a deep amber shade (Pantone 7509 C).
- Layer It Up
- Pile the hot caramel right on the baked base (keep it about 240°F/116°C). Smooth it out. While it’s still steamy, sprinkle your crushed Butterfinger bits over, pressing lightly so they stick.
- Let Everything Set
- Let it sit out at room temp (68–72°F/20–22°C) for about an hour or stick in the fridge for half an hour. The caramel should be set but give a little if you press it.
Ways To Make It Your Own
Take it up a notch—drizzle some melted chocolate swirled to 88–90°F/31–32°C right on top. Or toss some chopped pecans (a half cup or 57g) straight into the caramel. Want a sweet and salty fix? Shake a pinch of flaky sea salt (about a quarter teaspoon or 1.5g) on the Butterfinger layer before the bars cool down.
How To Keep And Serve Them
Stash your bars in something airtight:
- Leave ’em out at room temp (68–72°F/20–22°C): good for 5 days
- Fridge (40°F/4°C): stick around for 2 weeks
- Freezer (0°F/-18°C): lasts up to 3 months
Let them warm to room temp before you dig in for the best chew and flavor.

Common Questions
- → Is it okay to swap in regular caramels instead of caramel bits?
Yep, just use regular caramels and chop them up so they melt faster and easier.
- → What's making my caramel get tough?
The milk keeps things soft, so don't leave it out. Also go easy on microwaving or you'll wind up with a hard mess.
- → What's the best way to keep these bars fresh?
Stick them in a sealed container in your fridge. They'll stay good for a week. Sit them out for a bit before eating so they're not too cold.
- → Can I swap out the Butterfingers for another candy bar?
Totally. Try tossing in Snickers, Heath, or any crispy, chocolatey candy you love instead.
- → How can I get my chocolate drizzle to stay nice and smooth?
Microwave the chocolate in short bursts, giving it a little stir now and then. Overheating makes it thick or gritty, so keep an eye on it.
