Why You’ll Love this Recipe

• Kid-approved and activity-friendly — children will enjoy assembling and decorating the spiders.
• Perfect for Halloween parties, classroom treats, or a seasonal dessert platter.

Ingredients You’ll Need

• 1 cup oat flour — acts as the binder; you can make your own by pulsing rolled oats in a blender until fine.
• 1/2 cup peanut butter — creamy natural peanut butter works well; swap for any other nut or seed butter if preferred.
• 1/4 cup honey — a natural sweetener; sub with maple syrup if desired.
• 1 teaspoon vanilla extract — for extra flavor depth.
• 9 oz dark chocolate chips — for coating; choose a lower-sugar variety if you prefer.
• 2 teaspoons coconut oil — optional; helps create a glossy, hard chocolate shell.
• 30–36 thin pretzels — broken into pieces to form spider legs.
• 36 candy eyes — small candy eyes to complete the spider faces.

How to Make Chocolate Peanut Butter Balls

1. Prepare the dough. In a bowl combine the oat flour, peanut butter, honey and vanilla. Mix until smooth and evenly combined. Cover and chill for 30–60 minutes to firm up the mixture so it’s easier to shape.
2. Form the balls. Use a small cookie scoop or a spoon to form 1-inch balls. Place them on a baking sheet lined with parchment paper. This recipe yields about 18 balls.
3. Melt the chocolate. Melt the chocolate chips with the coconut oil in a double boiler or a heatproof bowl set over simmering water, stirring until smooth. Alternatively, microwave in 30-second bursts, stirring between intervals, until melted.
4. Coat and chill. Dip each peanut butter ball into the melted chocolate, fully coating it. Lift out with a fork or dipping tool and return to the parchment-lined sheet. Freeze or refrigerate for about 30 minutes until the chocolate shell sets.
5. Decorate as spiders. Break pretzels into small pieces for legs (you’ll need six legs per spider). Transfer any remaining melted chocolate to a small piping bag or plastic bag with a tiny corner snipped off. Pipe a small dab of chocolate onto each pretzel end and attach three legs to each side of the ball. Use a dab of chocolate to attach two candy eyes on each ball.
6. Serve or store. Serve chilled or store in the fridge or freezer. Keep them cold to prevent the peanut butter filling from becoming soft and melty.

Tips for Success

• Swap the peanut butter for almond, cashew, or sunflower seed butter to suit allergies or taste preferences.
• If you don’t have oat flour, pulse rolled oats in a blender until they form a fine flour. Other flours or even protein powders can work as binders, but textures will vary.
• Add mini chocolate chips or chopped nuts to the peanut butter mixture for extra texture.
• Use a cookie scoop for uniform-sized balls so they set and decorate evenly.
• Chill the dough well before rolling and chill the coated balls before decorating for cleaner results.
• Reserve some melted chocolate to “glue” on pretzel legs and candy eyes rather than using a separate adhesive.

Prepping and Storage

To store: Keep the spider balls refrigerated in an airtight container for up to 1 week. Lining the container with parchment paper prevents sticking.

To freeze: These treats freeze well for up to 3 months. Remove from the freezer and allow to thaw for about an hour before serving; they thaw quickly and remain delicious.
