Butterfinger Bars are incredible tasting, crisp, buttery oat bars, topped with a creamy milk chocolate/peanut butter icing. This easy recipe makes 24!
Preheat oven to 425°F.
Mix oats, brown and granulated sugars with melted butter in a large mixing bowl. Stir well, until fully combined. Lightly coat a 9x13 baking pan (bottom and sides) with non-stick spray, then pour oat mixture into dish. Spread mixture over bottom of the pan. Use the back of a large spoon to firmly press the ingredients together. When done, you should have a very firmly compacted oat mixture base.
Bake at 425°F for 10-12 minutes. When done, they will be crisp, golden brown around the edges. Transfer pan to a wire rack to cool.
Make the frosting while the bars are cooling. Melt milk chocolate chips (or 12 oz. milk chocolate Hershey bar) in a double boiler, along with the peanut butter. (See blog post for info on double boiler). Bring lower pan with water to a gentle boil, while stirring the chocolate chips and peanut butter in the pan above. Continue to stir until frosting is smooth and creamy, then remove from heat. TIP: For this recipe, it is best to NOT use all natural peanut butter. Once bars have cooled to room temp, they're ready to frost. Pour frosting over bars, and spread, to cover the entire surface. Let bars rest, so frosting can firm up, before attempting to cut or serve.
To slice: Run a butter knife around edges of the pan, and then use a sharp knife to cut the pan of bars down the middle in half. Lift an entire half of the bars from pan. They are so crisp they should hold together well. Cut this half into three equal sized long slices. Now slice each third into 4 pieces, using a sharp knife to make the cuts. Repeat with remaining half of the bars, and you will have 24 square bars, ready to eat. Store leftovers in an airtight container. Enjoy!
TIP: If substituting a Hershey large milk chocolate bar for the chocolate chips, be sure to break it into smaller chunks before melting it with the peanut butter! It will melt a LOT faster that way!
