This moist nectarine cake with blueberries is my go-to for summer gatherings or cozy afternoon treats. The recipe brings together juicy nectarines and burst-in-your-mouth blueberries, all nestled in a soft and tender crumb with a crunchy almond streusel topping. Whether you serve it for dessert or sneak a slice for breakfast, this cake always leaves guests asking for the recipe.
The first time I baked this, I had a basket of overripe nectarines to use up and some leftover blueberries from pancakes. Now it is a staple in my summer baking routine because my friends ask for it by name.
