Why Brioche Has More Calories Than Regular Bread
Brioche is an enriched dough. Along with flour, yeast, and water, it contains butter, eggs, and sugar, which give it its soft, golden crumb and rich flavor. Those extras raise the calories to about 350 to 380 per 100g, compared with roughly 265 for white sandwich bread. Brioche slices are also often cut thicker. The result is that one slice of brioche can have one and a half to two times the calories of a slice of regular bread.
Brioche vs Other Breads (Per Slice)

Fitting Brioche Into a Balanced Day
Brioche is delicious for French toast, sandwiches, and burger buns, and one slice fits easily into most eating plans. The calories add up quickly with toppings, though: a grilled cheese on brioche with two slices of cheese and butter can reach 500 calories or more. If you're tracking intake with a plan like the 1500 calorie meal plan, choose one slice instead of two, or save brioche for weekend breakfasts. Stale brioche also makes excellent breadcrumbs for French toast casseroles and coatings.
