Why You’ll Love These Chocolate Peanut Butter Magnum Bars

That shell. That crack. Chocolate and coconut oil set up into a thin, snappy coating that shatters the second you bite in.
Creamy, not icy. The peanut butter keeps the center soft and scoopable even straight out of the freezer.
Two bases, both winners. Greek yogurt goes tangy and light. Blended cottage cheese goes richer and denser. So which one are you making first?
Loaded with protein. Around 17 grams per bar. Yes, really!
No ice cream maker, no churning, no oven. Whisk, pour, freeze, dip. That’s the whole thing.

Ingredients for Chocolate Peanut Butter Magnum Bars

Short list, big payoff. Everything gets whisked in one bowl, and the chocolate shell is just two ingredients plus peanuts.

Yield: 5 to 6 bars

Base (Choose One)

1 ½ cups vanilla Greek yogurt or 1 ½ cups blended cottage cheese (extra protein)
¼ cup cocoa powder for deep chocolate flavor.
½ cup creamy peanut butter to keep the bars soft and scoopable when frozen.
2-3 tablespoons honey or agave to sweeten and keep the texture creamy.
1 teaspoon vanilla extract because chocolate and peanut butter both love it.
Pinch of salt. Don’t skip it! It wakes the whole thing up.

Chocolate Shell

2 cups milk chocolate chips for that classic sweet Magnum-style coating.
2 tablespoons coconut oil to thin the chocolate so it sets thin and snappy.
½ cup crushed or chopped peanuts for salty crunch in every bite.

I like using a full-fat cottage cheese here and blending it until there is not a single curd left. Take it further than you think you need to. And if you want a darker, less sweet shell, swap in semi-sweet chips. Both are delicious!

Step-By-Step Guide How to Make Chocolate Peanut Butter Magnum Bars

Mix the base. Whisk 1½ cups Greek yogurt or blended cottage cheese with ¼ cup cocoa powder, ½ cup creamy peanut butter, ¼ cup honey, 1 teaspoon vanilla, and a pinch of salt until completely smooth and creamy.
Fill the molds. Spoon the mixture into ice cream molds, tapping the molds gently on the counter to knock out air pockets.
Freeze 40 to 50 minutes. You want the mixture just firm enough to hold a stick upright.
Add the sticks. Insert a popsicle stick into each bar, then slide the molds back into the freezer.
Freeze 4 to 6 hours. Freeze until the bars are rock solid. This is what lets them release cleanly.
Make the chocolate coating. Melt 2 cups milk chocolate chips with 2 tablespoons coconut oil in 20 second bursts, stirring between each, until glossy and smooth. Then stir in ½ cup crushed peanuts.
Dip the bars. Unmold the frozen bars and dip each one, letting the extra chocolate drip off for a second or two.
Freeze to set. Set the dipped bars on a parchment-lined tray and freeze until the shell is firm, about 10 minutes.

My Best Tips for the Creamiest Magnum Bars

Let the chocolate cool a little before dipping. This is the trick that changes everything. Piping hot chocolate melts the surface of the bar and slides right off. Let it sit 3 or 4 minutes first.
Bars must be frozen solid. Rock hard. If there is any give at all, they’ll slump the moment they hit the warm chocolate.
Blend that cottage cheese longer than you think. Thirty seconds is not enough. Go a full minute or two until it’s silky, or you’ll taste the curds.
Work fast, one bar at a time. Keep the rest in the freezer while you dip. Trust me on this one.
Warm the molds for 10 seconds. A quick dunk of the outside of the mold in warm water and the bars slide right out. No wrestling.

Magnum Bar Variations to Try

Dark chocolate shell: Use dark or semi-sweet chips for a shell that’s less sweet and a little more grown up.
Crunchy peanut butter: Swap the creamy for crunchy and get peanut bits in the center too.
Almond or cashew butter: Both work beautifully. Top with chopped almonds instead of peanuts.
Salted caramel drizzle: Drizzle a little caramel over the set shell and hit it with flaky salt.
Snickers style: Press a few chopped peanuts into the center before freezing. Also try these No-Bake High Protein Snickers Bars while you’re at it!
Extra protein: Stir a scoop of chocolate protein powder into the base and add a splash of milk to loosen it back up.

How to Store Chocolate Peanut Butter Magnum Bars

Store the bars in the freezer in an airtight container for up to 2 months. Wrap each one in parchment or wax paper first so the chocolate shells don’t stick together, then stack them in a freezer bag or container.

Freezer: Up to 2 months, wrapped individually.
Before serving: Let the bars sit out for 3 to 5 minutes. The center softens and the shell cracks better.
Don’t refrigerate: These need to stay frozen. The fridge turns the center to pudding.

Chocolate Peanut Butter Magnum Bars FAQs

Can I Make Magnum Bars Without Ice Cream Molds?

Yes. Line a loaf pan with parchment, spread the base about an inch thick, freeze until solid, then slice into bars and insert sticks. Dip them the same way. They won’t have the rounded Magnum shape, but they taste identical. A silicone popsicle mold also works well.

Do Cottage Cheese Magnum Bars Taste Like Cottage Cheese?

Not at all, as long as you blend it completely smooth. The cocoa powder and peanut butter cover any tang, and the texture reads as rich and creamy. Blend the cottage cheese by itself first until it looks like a thick pudding, then whisk in everything else.

Why Did My Chocolate Shell Crack or Slide Off?

Chocolate that’s too hot is usually the culprit. It melts the surface of the bar and slips off before it can set. Let the melted chocolate cool for a few minutes so it thickens slightly. Also make sure the bars are frozen completely solid, and don’t skip the coconut oil, because it keeps the shell thin instead of thick and brittle.

How Much Protein Is in These Magnum Bars?

Around 17 grams per bar with either base. Greek yogurt and blended cottage cheese land in a similar range, though cottage cheese usually edges it out by a gram or two. The peanut butter and peanuts add a few more grams on top.

Nobody is going to guess these started with a tub of yogurt. The shell snaps, the center is thick and creamy and full of peanut butter, and the whole batch lives in your freezer waiting for a hot afternoon. Pull out your molds, melt that chocolate, and go make a batch. Happy freezing!
