Heat your oil to 350°F before frying the biscuit dough—too hot and they'll burn outside while remaining raw inside, too cool and they'll absorb excess oil and become greasy.

Gently warm the peanut butter mixture before dipping to achieve a smooth, pourable consistency that coats evenly without pooling.

Dip donuts in glaze, let it set for 30 seconds, then dip again for a luxurious double layer that prevents glaze from sliding off.

Lightly toast the crushed peanuts in a dry skillet for 2-3 minutes before sprinkling to intensify their flavor and add a subtle crunch that elevates the entire donut.

Ensure your peanut butter, milk, and vanilla extract are at room temperature when mixing the glaze to prevent lumps and create a silky, homogeneous coating.
