Prep Time: 15 minutes | Cook Time: 15-20 minutes | Total Time: 35 minutes | Makes: 18-20 treatsGooey vegan sweet potato brownies with chocolate chips stacked on a plate, healthy dessert option, gluten-free, plant-based indulgent treat, Waggy Chef.


Ingredients

Scale
  • 1 can (3.75 oz) sardines in water, drained (plain sardines with no added seasonings)
  • 1 cup cooked sweet potato, mashed (roasted until fork-tender, completely cooled)
  • 1/2 cup oat flour (store-bought or homemade from ground oats)
  • 1 egg (fresh, room temperature preferred)

Instructions

  1. Preheat your oven to 350°F and line a baking sheet with parchment paper—essential for preventing fish-based treats from sticking.
  2. Mash sardines with a fork in a large bowl until broken up but still textured, then add mashed sweet potato, oat flour, and egg.
  3. Mix until well combined into this gorgeous orange mixture flecked with sardine pieces that looks absolutely premium.
  4. Roll mixture into walnut-sized balls and place on your prepared baking sheet, then flatten with a fork for even baking.
  5. Bake for 15-20 minutes until firm and golden, creating gourmet-looking treats that smell like a high-end seafood restaurant.
  6. Let cool completely before serving—this ensures perfect texture and safe serving temperature.

Notes:

  • Always let cool completely before serving—hot treats can burn your dog’s mouth
  • Amber goes absolutely crazy for these omega-3 powerhouses
  • Use only plain sardines in water with no added seasonings for safety

Storage Tips:

  • Keep in an airtight container in the refrigerator for up to 5 days
  • The sardine content requires refrigeration to prevent spoilage
  • Freeze individual treats for up to 3 months (perfect for portion control)
  • Toss if you see any mold or if they smell fishy rather than fresh

What Makes This Recipe Special:

These treats combine heart-healthy omega-3 fatty acids from sardines with fiber-rich sweet potato, creating nutritionally complete treats that support cardiovascular health, brain function, and digestive wellness. The small fish provide concentrated nutrition while sweet potato adds natural sweetness that balances the oceanic flavors perfectly.

Mix It Up (Dog-Safe Variations):

Joint Support: Add a tiny pinch of turmeric for anti-inflammatory benefits that complement the omega-3s—perfect for senior dogs like my 8-year-old Amber.

Omega Boost: Include a tablespoon of ground flaxseed for even more omega-3 fatty acids and fiber benefits.

Garden Fresh: Mix in finely diced cooked carrots for extra beta-carotene and satisfying crunch that complements the fish beautifully.
