Before anything else, I preheat my oven to 350°F (175°C). Then, I prepare the Bundt pan by greasing it well with butter and dusting it with flour, or using a nonstick baking spray that contains flour. Don’t skip this step — Bundt pans can be tricky, and proper greasing ensures the cake releases cleanly.
Next, I place the freeze-dried strawberries in a zip-top bag and use a rolling pin to crush them into fine crumbs. You can also pulse them in a food processor if you prefer. This adds intense strawberry flavor and beautiful specks of red throughout the batter.
In a large mixing bowl, I combine the strawberry cake mix, vanilla pudding mix, crushed freeze-dried strawberries, milk, vegetable oil, and eggs. Using an electric mixer on medium-high speed, I beat everything together for about 2 minutes, or until the batter is smooth and well incorporated. It should be slightly thick, rich, and beautifully pink.
I pour the batter into the prepared Bundt pan, smoothing out the top with a spatula. Then, I gently tap the pan on the counter once or twice — this helps eliminate any large air bubbles that could create gaps in the finished cake.
Bake the cake in the center of the oven for 40 to 45 minutes, or until a toothpick inserted into the thickest part comes out clean. Your kitchen will start to smell like strawberries and vanilla — absolutely irresistible!
Once baked, I let the cake cool in the pan for 10 minutes before inverting it onto a wire rack. Cooling in the pan allows the structure to firm up slightly so it holds its shape. After that, I let it cool completely on the rack before moving on to the glaze.
