Why It Works

  • Allowing the peanut butter filling to ripen for a few days results in a stronger, richer flavor.
  • Adding the final coat of chocolate conservatively and allowing it to settle keeps the candy molds from overflowing.

Here's a question I ask each year when Easter candy hits the shelves: why are regular Reese's peanut butter cups gluten-free but the seasonal shapes, like eggs, not gluten-free? While I'm sure it has something to do with how the seasonal items are shaped, the whiny part of me just wants to say, "Whhhhhhhy?!?!" Because even though I can count on one hand how many times I eat peanut butter cups during the year, I love those peanut butter-filled eggs.

So, instead of whining and spending yet another Easter without one of my favorite candies, I decided to make a batch myself. It may not be quite as easy as picking up an egg or two at CVS, but the process isn't hard—it just requires the right tools and a little time.

Unlike homemade peanut butter cups, which can be made in a muffin pan, homemade peanut butter eggs require a candy mold. This doesn't need to be an expensive investment; the mold I used cost about three dollars. After selecting your mold—a harder process than you'd think, there are lots of choices!—select your chocolate. I like milk chocolate, but dark or white works well, too. And if you don't want to temper chocolate, select a high-quality confectionery coating. Some coatings, like the ones sold at craft stores, taste waxy and aren't gluten-free. Merckens' coatings, my preferred brand, taste very similar to a Hershey's kiss-level chocolate.

After you've selected your chocolate and egg mold, you're ready to make a batch! Er, almost. The filling, a dough made with peanut butter, confectioner's sugar, and butter, tastes better after ripening for about two days. So stir the filling together, throw it into the refrigerator, and forget about it. Okay, fine. Maybe sample it before you throw it into the fridge. You'll notice it's a little sweet. After the ingredients have a chance to mingle for two days, the sweetness settles down and the filling tastes very similar to a Reese's peanut butter cup.

Finally, it's time to make some candy! Here's how to make the eggs:

A piping bag full of tempered chocolate is held above an egg-shaped candy mold.

Line a rimmed baking sheet with parchment paper. Set the candy mold inside the pan. Don't grease the mold. Next, place your tempered chocolate or melted confectionery coating into a pastry bag and fill each cavity about 2/3 of the way with chocolate.

The chocolate-coated mold is inverted over the lined baking sheet and excess chocolate is allowed to drip off.

Turn the mold over onto a parchment-lined baking sheet. Shake and rotate the mold. The melted chocolate should coat each cavity. After shaking out the excess chocolate, inspect each cavity. If there are any bare spots, dot a little melted chocolate onto them with either a small brush or your fingertip.

Excess chocolate has been swept away from the mold.

Quickly sweep a metal spatula across the mold. This clears excess chocolate from the edges of the mold. After you do this, the mold might look smeared with chocolate. That's fine. The thin chocolate breaks easily away from the finished eggs. Allow the chocolate to set up, but don't refrigerate it to speed the process. The finished chocolate looks flat and almost fudgy.

Pat your filling into the cavity; the amount will depend on the size of your mold. To prevent it from sticking to your finger, dip your finger into a little powdered sugar beforehand. You want the peanut butter filling to be about 1/8-inch below the edge of the mold. If the peanut butter filling sits too high, it's hard to seal the mold, so you're better off having too little filling than too much.

Place more chocolate into your piping bag. Cap each mold. The easiest way to do this is to go slow, using a zigzag pattern. STOP before the mold is fully capped. When you tap the mold, the small space you left will fill in. If it doesn't, just go back and add more chocolate. If you overfill, though, the chocolate will ooze past the edges of the mold.

Chill for about 10 minutes and carefully remove the eggs from the mold. They usually fall out pretty easily.

Don't whack the mold or you'll break the egg, like I did here! (Cook's treat, right?)

Homemade Peanut Butter Cup Eggs Recipe

Prep 25 mins

Total 48 hrs 35 mins
Makes 12 chocolate eggs
Cook Mode (Keep screen awake)

Ingredients

  • 1/2 cup creamy peanut butter (see note)
  • 1 cup sifted confectioner's sugar
  • 2 tablespoons butter, melted (use coconut oil if dairy-free)
  • 1 pound chocolate, tempered or candy coating (see note)

Directions

  1. In a small bowl, stir together peanut butter and confectioner's sugar until smooth. Add melted butter. Stir until incorporated. Cover bowl. Chill for two days.

  2. Line a baking sheet with parchment paper. Place tempered chocolate (or melted confectionery coating, see note) into a pastry bag fitted with a small piping tip, or a disposable plastic bag with the end snipped off. Fill each egg cavity about 2/3 of the way with chocolate.

    The egg molds are partially filled with tempered chocolate.

  3. Turn mold over onto prepared baking sheet. Shake and rotate the mold. The melted chocolate should coat each cavity. After shaking out the excess chocolate, inspect each cavity. If there are any bare spots, dot a little melted chocolate onto them with either a small brush or your finger.

    Quickly sweep a metal spatula across the mold. This clears excess chocolate from the edges of the mold. After you do this, the mold might look smeared with chocolate. That’s fine. The thin chocolate breaks easily away from the finished eggs.

    Allow the chocolate to set up. Don’t refrigerate.

  4. Fill each cavity with peanut butter filling until it's about 1/8th-inch below the edge of the mold. Amount varies depending on the size of your mold.

  5. Cap each mold with melted chocolate. Use a zig zag or circular pattern to close each cavity. When the cavity is almost closed, stop. Tap the mold gently. The chocolate should flow a little and close the mold. If it doesn't, pipe a little extra chocolate into the mold to close.

  6. Chill for about 10 minutes. Invert mold. Tap gently. Eggs should come out easily. If they don't, the chocolate might not be set. Return to the refrigerator for a further 15 minutes and try again until they all come out cleanly. Set peanut butter eggs on a wire rack set in a rimmed baking sheet and drizzle with more chocolate if desired. Finished eggs can be stored in a sealed container at room temperature for up to 2 weeks.

Egg-shaped candy mold, pastry bag and small piping tip (optional), metal spatula

Make-Ahead and Storage

Finished eggs can be stored in a sealed container at room temperature for up to 2 weeks.

Notes

Be sure to select commercial peanut butter for this recipe. Natural peanut butter, which just contains peanuts and sometimes salt and sugar, makes a filling that's too runny.

Select either dark, milk, or white chocolate. If you don't want to temper your chocolate, use a high-quality confectionery coating. If you plan to use confectionery coating, here's how to melt it: Place confectionery coating in a microwave-safe bowl (I recommend a glass 2-cup measure.) Heat the coating for 30 seconds. Remove the cup from the microwave and stir. Repeat this process, removing the coatings every 30 seconds from the microwave and stirring, until fully melted.
