Try this Churro Bars recipe
Unsalted butter performs the heavy lifting in this recipe. Melting and heating the dairy fat drives off water content and toasts the milk solids until amber colored. This process concentrates flavor through the Maillard reaction. Cooling the fat for twenty minutes prevents premature egg coagulation when the wet ingredients are combined.
Proper flour incorporation dictates the final density of the baked pan. Overmixing activates gluten networks, producing a tough crumb instead of a tender bar. Stop stirring the all-purpose flour the moment dry streaks disappear from the bowl. Lining the nine-by-thirteen-inch baking dish with foil ensures clean extraction after the treats cool completely on a wire rack.
