These easy 5-ingredient brownie bites are fudgy, gooey, and packed with a swirl of peanut butter and a boost of protein. Perfect for snacking, lunchboxes, or a healthy dessert that feels indulgent but is secretly wholesome.
Do not overmix the batter for best fudgy texture. Swirl peanut butter gently for pretty ribbons. Start checking for doneness at 10 minutes—overbaking leads to dryness. For vegan, use flax eggs and plant-based protein powder. Store in airtight container at room temp for 3 days, refrigerate for up to a week, or freeze for 2 months.
