"The cookies use both malted milk powder and Whoppers for a double hit of malt. Matled milk powder is typically sold near sweetened condensed milk, evaporated milk, hot chocolate mix, pancake syrup, etc. in most grocery stores. I bought the 12-ounce 'carton' size of Whoppers that's sold in the candy aisle and used about half. The Whoppers turn extra crunchy (but not in a tooth-breaking way) and create a fabulous texture dichotomy. The buttery soft, tender, creamy cookie dough that's studded with big chunks of crispy Whoppers is so addictively good. Semi-sweet chocolate chips balance the milk chocolate Whoppers, and two kinds of chocolate are always better than one. The cookies are very soft, but also very chewy. If you like chewy cookies that you can really sink your teeth into, combined with all that crispy texture from the Whoppers, you'll love these. Chilling the dough before baking is essential so cookies don't spread too much...."
