Ingredients
Peanut Butter Bars
8 tablespoons salted sweet cream butter softened
3 cups creamy peanut butter
2 teaspoons pure vanilla extract
4 cups powdered sugar
Chocolate Ganache
12 ounces semi-sweet chocolate chips
2 tablespoons vegetable oil
Instructions
Peanut Butter Layer
Line a 9×13-inch baking dish with parchment paper. Set it aside.
Using either a stand mixer or a medium-sized mixing bowl and a handheld mixer on medium-high speed, beat the softened butter for 1 minute until smooth.
Add the peanut butter and vanilla. Continue mixing for 1 minute until smooth.
Lower the mixer speed to medium-low and add the powdered sugar 1 cup at a time, mixing well after each cup. Increase the mixer speed to medium-high and continue mixing until completely incorporated.
Using either a silicone spatula or an offset spatula, evenly spread the peanut butter mixture in the bottom of the prepared baking dish.
Chocolate Ganache
Add the chocolate chips and oil to a small microwave-safe bowl. Heat for 1 minute, stir, and continue to mix in 15-second intervals until the mixture is completely smooth.
Using a silicone spatula or an offset spatula, evenly spread the chocolate over the peanut butter layer. Cover and chill in the refrigerator for 15 to 20 minutes.
Remove the baking dish from the refrigerator.
Carefully slice the buckeye bars into 15 (2½-inch x 3-inch) pieces.
Cover the baking dish and return the bars to the refrigerator to continue chilling for an additional 1 hour and 45 minutes.
Remove the bars from the dish by the parchment paper.
You may need to carefully re-slice the bars.
Serve immediately”
