Three ingredients, one bowl, one pan, and under 40 minutes: that is all it takes to produce a batch of lemon bars that serves up to 12 people. Built around sweetened condensed milk, lemon juice, and yellow cake mix, this recipe skips eggs, oil, and water entirely — and still delivers a melt-in-your-mouth result. At a total cost of under $6, it is one of the most budget-friendly desserts a home baker can keep in rotation.
