1-First Step: Mise en Place Gather all tools: donut pan for baking, or heavy pot and thermometer for frying. Preheat oven to 425°F if baking, or heat oil to 375°F if frying. Measure ingredients precisely for perfect texture in your homemade blueberry cake donuts.

2-Second Step: Mix Dry Ingredients In a large bowl, whisk 2 cups flour, 3/4 cup sugar, 2 tsp baking powder, 1 tsp nutmeg, and 1/2 tsp salt. This base creates the signature cakey crumb. Sift if lumps appear for even rising.

3-Third Step: Combine Wet Ingredients In another bowl, beat 2 eggs, then add 3/4 cup buttermilk, 1/4 cup melted butter, and 1 tsp vanilla. Stir until smooth. Buttermilk tenderizes the batter for moist results.

4-Fourth Step: Fold in Blueberries and Batter Pour wet into dry, stirring gently until just combined. Avoid overmixing to keep donuts tender. Fold in 1 cup fresh blueberries coated in flour. Batter should be thick like muffin mix.

5-Fifth Step: Shape and Cook For baked wild blueberry donuts: Grease donut pan, pipe batter 3/4 full. Bake 10-12 minutes until springy. Cool 5 minutes. For frying: Drop spoonfuls into hot oil, fry 1-2 minutes per side until golden. Drain on paper towels. Inspired by professional techniques.
