Use a high-quality chocolate protein powder and sift it with the cocoa powder to prevent clumping and ensure a smooth, fudgy texture throughout your overnight oats.

Heat your dark chocolate ganache to just 110-115°F before topping to achieve that silky, pourable consistency while keeping it warm enough to partially set the sprinkles.

Use a 1:1.25 ratio of oats to non-dairy milk to account for absorption overnight—this prevents a too-thick porridge while maintaining the creamy brownie batter texture.

Whisk your nut butter with a splash of hot milk before adding to the oat mixture to fully incorporate it and eliminate any separated oil pockets for uniform richness.

Add sprinkles just before eating rather than during assembly to preserve their vibrant color and prevent dye bleeding into the oats overnight.
