Literally anyone who knows me knows I’ll take any excuse to add peanut butter to my meals. This healthy and balanced breakfast tastes just like dessert, and it’s packed with protein to fuel your day. The cake is soft and fluffy, layered with creamy vanilla yogurt, rich chocolate ganache, and topped with a swirl of peanut butter and mini Reese’s cups. It’s indulgent yet macro-friendly, and I hope you try it and enjoy!
