To properly cool your mini bundt cakes, transfer the pan to a wire rack immediately after baking. Give them about 10-15 minutes to cool down – just enough time for the cakes to firm up for easy removal without falling apart. Howvere, you need to be cautious not to leave them in the pan too long, as they can become overly moist and stick to the pan. This sweet spot in cooling time ensures your cakes are perfectly shaped and moist.
